In the ten years since Apple launched its first iPhone, mobile devices have gotten bigger screens, more features, and more powerful processors – all of which translates into bigger batteries.

For consumers, battery life remains a top priority. A quick search online brings up thousands of articles written on how users can improve the battery life of their phones, tablets, and wearables, even though most of these articles offer tips and tricks that only are marginally beneficial at best.

The rechargeable batteries used in smartphones, laptops, and now electric vehicles, are made from lithium. Traditionally, lithium carbonate is extracted from brines gathered in salt-rich lakes. This method is extremely time consuming, taking anywhere from 12-18 months, and also inefficient with a low extraction rate. Since 2010, POSCO has been working to develop new technologies for more efficient, more eco-friendly lithium extraction methods. Earlier this month POSCO announced the opening of its lithium extraction plant, PosLX, in Korea that is able to extract lithium from recycled batteries. In addition, while working on the traditional extraction methods from saline lake water, POSCO has also found a way to reduce extraction time from 12 months to less than one day.

If MWC is any indication, mobile device manufacturers are going to continue to need more lithium-ion batteries, and POSCO is now well positioned to be a leader in providing lithium carbonate. In the gallery below, we take a look at some of the improvements made by the leading mobile device manufacturers.

Samsung Galaxy Tab S3

Even though Samsung is waiting until March to unpack its new Galaxy S8 smartphone, they used the opportunity at MWC to unveil the update to their popular Galaxy Tab series. The new Galaxy Tab S3 improves upon many of the features in the S2 and now comes equipped with Samsung’s S Pen Stylus. However, the 10” model includes just a 6000mAh battery. While this is a modest improvement over the Galaxy Tab S2’s 5870mAh, it pales in comparison to some other tablets like the 9243mAh battery included in Google’s Pixel C.

LG G6

LG announced its new flagship device, the LG G6, in Barcelona on Sunday. Having ditched the rather unpopular design of the G5, LG went in a completely new direction with the G6. It features a large, nearly bezel-free display, water & dust proofing, and three cameras. Last year, LG was one of few remaining manufacturers to still include a removeable battery when it launched the G5, but this year’s device drops that distinction and sees LG follow suit with a non-removable battery. To do this, LG increased the battery size from 2,800mAh to 3,200mAh, includes quick charge capabilities, and wireless charging (US models only).

Huawei P10

In 2015, Huawei’s P9 was released to generally favorable reviews. It included powerful specs with an elegant, minimalist design – and it was placed at a price range that was more affordable than many of its competitors. This year, Huawei has launched its P10 model that carries over many of the same features found on its P9. Huawei’s P9came in two sizes, one that included a 3000mAh cell and a larger one with a 3200mAh. The P10 also comes in two sizes but Huawei has decided to upgrade the size of both batteries to 3200mAh and 3750mAh respectively.

BlackBerry KeyOne

Blackberry continues to stand out as the one major manufacturer still using a physical keyboard with its new KeyOne. In efforts to extend the phone’s running time, BlackBerry included a power-efficient Snapdragon 625 processor in addition to a fairly large 3505mAh battery. Both of these together should see the KeyOne hold up against BlackBerry’s first Android phone, the Priv which included a 3410mAh battery and was listed at 22.5 hours of mixed usage.

Nokia 3310

Nokia brought some nostalgia to its announcement by releasing an update of the wildly popular 3310 phone that first debuted in September 2000. As a basic feature phone, it comes with an Opera browser, but not much else. With limited resources being used by apps and operating systems, the battery on the Nokia 3310 gives it a standby time of 31 days with a talk time listing of 22 hours.

Consumers expect to be able to go a full day without worrying about charging their phone. However, advancements in mobile technology also require more resources – forcing manufacturers to constantly find a balance between slimmer phones and an increasing drain on batteries.

As seen at MWC, the demand for lithium continues to increase, and it is expected to skyrocket as other industries, such as electric vehicles, grow. POSCO’s work on lithium extraction technology is important because we have found a way to extract lithium in an eco-friendly way that also significantly reduces time. These improvements will create a notable impact moving forward as global consumer needs for lithium-ion batteries continue to rise.

GM plans to launch its plug-in hybrid car (PHEV) “Bolt” during the second half of this year. PHEV is a hybrid car that runs on an electric motor, which can be recharged by plugging it into an electrical power source. It switches to run on the combustion engine when the batteries are depleted.

POSCO ICT plans to build EV-charging stations at 120 key locations as the business partner of GM Korea and will also implement a related membership program.

As POSCO ICT has been selected as the producer of EV chargers for GM Korea, it plans to provide charging services with public charging stations at 120 key locations. Locations will include after-sales centers, GM sales stores, and big marts.

On top of public stations, it is building home charging stations for drivers of GM’s EV and is also implementing a membership program. Through this program, drivers can use the existing charging stations available at big marts, cinemas, and department stores across the country in addition to newly built stations.

 Expansion of the facility to 300 stations to become largest privately-owned infra

Apart from the 120 stations to be built under the deal with GM, POSCO ICT will increase the number of its own stations from 250 to 300 by the end of the year, making it the owner of the largest privately-owned EV charging infra.

It will build and run the infra by targeting the facilities that drivers visit often and spend time at. Drivers will be able to charge their car by driving only 4 to 5 km each time.

The Ministry of Trade, Industry and Energy recently announced that it would build high-speed charging stations, one within each 2-km radius, at key locations such as petrol stations, large supermarkets and parking lots in Seoul and Jeju by the end of this year. A total of 490 charging stations will be established. Since the Ministry will also build a total of 30,000 slow chargers at 4,000 apartment complexes across the country, the spread of electric vehicles in Korea is likely to be accelerated.

The interest in the electric vehicle is increasing due to climate environmental issues and the strive towards energy reduction. POSCO ICT will further expand its cooperation with electric car manufacturers in order to grow the charging infrastructure, no longer hindering the spread of electric vehicles within the country.

The use of lithium is soaring. It’s gone from 70,000 tons in 2002 to 170,000 tons in 2014, and some estimate that could grow to 470,000 tons by 2025. And with that surging demand, POSCO has identified lithium as a major product for the company’s future business growth.

“POSCO is accelerating the lithium material industry after lithium was selected as the new growth business that will lead the future of the company,” said CEO Ohjoon Kwon when he became the head of POSCO in 2014. “If steel is the ‘rice’ of the current industry, lithium will take on that role in the future.”

What Is Lithium?

For such a common element, most people don’t know a lot about lithium. The soft, silver-white metal is the third element on the periodic table, making it the lightest metal and least-dense solid element. It is found commonly around the Earth, but because it is highly reactive, it is rarely found in a pure, elemental form, and instead is present in very low concentrations in sea water, in rock in the Earth’s crust (especially granite), and in brines and salt lakes.

Importantly, lithium is also very energy-dense—in fact, it has twice the energy density of the next closest alternative—making it a great option for portable energy storage applications.

Lithium, however, is quite difficult to extract. In the past, it was gathered on large salt farms, and required months for the water to evaporate, leaving lithium salts behind. But in 2010, POSCO (with support from the Ministry of Trade, Industry and Energy) developed a high-efficiency technique for extracting lithium from water. Instead of a large and slow evaporation process, POSCO uses a chemical reaction to extract the lithium more quickly. It also increased its extraction capabilities to 200 tons per year.

Now POSCO is expanding its lithium processing even more, opening a cutting-edge lithium processing plant at Pozuelos Salt Lake in Argentina this year. Built high in the Argentine mountains, some 4,000 meters above sea level, the new plant had a groundbreaking ceremony on February 14, and once operational later this year it will boost POSCO’s annual lithium production to 2,500 tons.

Lithium in IT Gadgets

Lithium is a key element in lithium-ion batteries, which power many of our most popular devices, including mobile phones and laptops. Lithium-ion batteries can generate a 3 volt charge in each cell, much more than lead-acid and zinc-carbon cells, meaning it can provide more power more efficiently.

For portable devices, like mobile phones, size and weight are at a premium, so being able to contain more power means being able to create smaller and more useful mobile gadgets. Lithium-ion batteries are also commonly used in portable power tools, like drills, saws and lawn trimmers.

In addition to the success of lithium-ion rechargeable batteries, regular lithium batteries are also in high demand, often used in such devices as pacemakers, cameras and watches.

Lithium for a Green Future

Beyond gadgets, lithium-ion batteries are a big part of the future of green energy. Solar, wind and other renewable energy sources are important, but you still need an energy storage device to store that power between peaks and valleys.

In particular, they are at the heart of the latest developments in electric cars, like the very popular Tesla cars. And as an electric car usually requires around 40 kilograms of lithium for its lithium-ion battery, that adds up quickly. In fact, Goldman Sachs estimates that the amount of lithium needed for electric car batteries will go up 11-fold over the next nine years.

But the eco-friendly applications don’t stop with cars. Motorcycles, large-scale residential facilities and industrial facilities are all increasingly using lithium-ion batteries, too.

POSCO Leads the Way Toward a Lithium Future

“With the supply of electric cars and the development of smart grid technology, the market is expected to result in massive growth,” noted CEO Kwon. “In order to raise competitiveness of the domestic secondary cell industry, it is crucial to develop lithium resources along with localizing core material.”

Pozuelos Lake, where POSCO is building its new processing facility, covers 106 square kilometers, and has an estimated 1.5 million tons of lithium reserves. That’s enough for millions of large-scale lithium-ion cells, which is good news for the environment and our planet.

“We have brought our advanced and environmental-friendly technology to extract and process lithium,” said Kwon at the ceremony. “We will continue to expand our operations in Argentina and boost cooperation with our partners here to create a win-win solution for all.”

POSCO’s lithium processing plant will be located at Pozuelos Salt Lake, which rises 4,000 meters above sea level. It will have an annual processing capacity of 2,500 tons of high-purity lithium for rechargeable batteries, and will supply them to domestic and international mineral manufacturing enterprises that produce minerals for car batteries. Considering the fact that it takes an average of 40 kilograms of high-purified lithium to make a single electric car battery, this equates to about 60,000 electric cars a year.

Pozuelos Lake, which spans 106 square kilometers and is estimated to have about 1.5 million tons of lithium reserves, is considered to be an optimal location to produce lithium.

Pozuelos Salt Lake is considered to be an optimal location for producing lithium. POSCO plans to extract and process about 2,500 tons of lithium annually after completing the construction of the plant here by the end of this year.

Earlier this year, POSCO signed a supply contract with Lithea Inc. of Argentina, the company owning the mining rights of Pozuelo Salt Lake and securing the stable permissions to access the lake. POSCO also set a solid foundation for entering the lithium business through developing an independent technology that is economically-friendly.

The Pozuelo Salt Lake plant will use POSCO’s innovative and independent technology that dramatically reduces the lithium extraction period, which usually takes more than a year, through chemical reaction.

POSCO’s high-efficiency lithium extract technology, which was developed with support from the energy resource technology development project led by the Ministry of Trade, Industry and Energy in 2010, does not require a large area of salt farm compared to the conventional evaporation and extraction method, and is less affected by changes in climate. Moreover, since there is very little loss when extracting lithium, it is possible to extract the same amount of lithium, compared to the conventional process, even by using a less amount of salt water. Therefore, POSCO’s high-efficiency lithium extract technology is an economical and environmental-friendly technology.

POSCO’s lithium business is one of the main businesses that has taken the lead in developing production technologies since 2010, when POSCO CEO Ohjoon Kwon was the Director at the Research Institute of Industrial Science & Technology (RIST). Since the development of the company’s high-efficiency lithium extract technology in 2010, POSCO has been beefing up pilot production from 2 tons to 200 tons, while examining the economic viability of the technology.

The world’s lithium market has grown from 70,000 tons in 2002 to 170,000 tons in 2014, and is a promising market that is projected to grow to 270,000 tons by 2020. Of this, the lithium market for electric car batteries, which will be produced by POSCO, is expected to be 135,000 tons, accounting for half of the entire market. Nonetheless, the Korean battery manufacturers that depend entirely on lithium imports are currently suffering from unstable supplies and price hikes.

With an increase in sales of electric cars worldwide including China, which is aiming to further promote electric cars across the nation, the lithium industry is welcoming POSCO for its new lithium business. Due to the recent shortage of lithium supplies and price increases, global battery manufacturers are already starting to discuss the possibility of lithium supply contracts with POSCO.

Meanwhile, CEO Ohjoon Kwon had an exclusive meeting with Mauricio Macri, the president of Argentina, on February 15 following the ceremony marking the construction of the steelmaker’s lithium processing plant in Argentina. Kwon discussed POSCO’s excellent lithium extract technology and the technology development process. He also talked about future plans for building a consistent and cooperative relationship with Argentina for lithium development.

Thanks to the high enthusiasm and active investment on the part of POSCO and various companies in developing new business opportunities, Korea’s technology is making its way to the top.

Shall we take a closer look into Korea’s globally recognized advanced materials and energy sector?

#1. Secondary Batteries

Secondary batteries are known as one of the three most significant electronics of the 21st century, along with semiconductors and digital displays. Secondary batteries can be recharged and reused unlike the generic disposable kind. Corresponding to the rising interest in eco-friendly energy such as electric cars, the lithium secondary battery market soared 20% annually over the past five years.

According to a report by B3, a Japanese market research company, this year’s lithium ion secondary battery market is expected to increase 24% compared to last year.

Secondary batteries are classified by the material used; there are Nickel, lithium ion, lithium polymer, and nickel zinc batteries. Among these, the most promising is the lithium ion secondary battery which is widely used in various appliances including mobile electronic devices.

The Advantages of Environment-Friendly Secondary Batteries

 The most important reason secondary batteries are so influential in today’s energy industry is that its impact on the environment is minimal. Unlike fossil fuel, secondary batteries do not produce harmful emissions, making it an attractive energy source for cars. Also, because it does not require an internal combustion engine, there is no need to worry about making too much noise. Isn’t that wonderful?

From Automobiles to IT: The Various Applications of Secondary Batteries

Secondary batteries are thrown into the spotlight as the key to eco-friendly growth in various fields such as the automobile, IT and energy industries.

 From various IT devices to electric cars, secondary batteries are being used more and more frequently. Recently, secondary batteries are mostly used in mobile phones because they are light and suitable for storing high amounts of power.

In the automobile industry, the development and implementation of next-generation secondary batteries for electric cars will be a truly significant feat that will change the industry forever.

Game Changer: POSCO develops revolutionary lithium extraction technology

Korea is the world’s largest manufacturer of secondary batteries, but it has also been 100% dependent on imports for the core material lithium. To solve this problem, POSCO and the Research Institute of Industrial Science & Technology (RIST) jointly developed a revolutionary lithium extraction technology.

(POSCO’s Pilot Plant (Phase 2) located at the Maricunga project near the city of Copiapó, Chile)

The lithium extraction technology was developed after the successful installment of a pilot plant (phase 2) located at the Maricunga project near the city of Copiapó, Chile.

The chemical lithium extraction technology, which was developed by POSCO’s own research unit, reduces recovery time from around 12 months to just eight hours! It also increases the lithium recovery rate from a maximum of 30% using traditional evaporation ponds to more than 80%.

In a time when secondary batteries are in the limelight, POSCO’s new technology could possibly be a game changer in various next-generation industries such as electric cars and smart grids. We hope to lead the global green industry with this awesome technology!

#2. PosMAC, the Unmeltable Steel

(The demand for highly durable and cost-efficient PosMAC is on the rise in the solar panel industry)

We usually consider steel as vulnerable to rust and corrosion over time. However, Korea’s leading steelmaker POSCO has developed a revolutionary steel by the name PosMAC. PosMAC is free from rust and corrosion for 10 to even 50 years!

The researchers at POSCO felt the need to develop a highly durable steel suitable for use in sites vulnerable to corrosion such as livestock handling facilities or coastal structures. The result was a futuristic multi-purpose steel that not only ensured long-term stability, but also added to the cleanliness and aesthetic of structures.

PosMAC is highly durable to moisture, heat and various chemicals while being affordable. PosMAC is also highly resistant to alkali and ammonia, which makes it highly suitable for use in livestock handling facilities or in situations where components are in contact with concrete tar.

We expect the corrosion-free PosMAC to be a significant contribution to the steel market in areas struggling with rusty steel!

#3. Substituting Fossil Fuel with Marine Bioenergy

Last but not least is the marine bioenergy industry. Marine bioenergy is an alternative energy produced through the refinement and fermentation of marine biomass such as seaweed. By substituting fossil fuel, bioenergy aims to narrow the gap between energy supply and demand!

Korea is currently heavily dependent on imports for energy, with 97% of the country’s energy being imported. Thus, it is crucial to reduce the dependency while finding out a way to produce energy independently. Marine bioenergy has been thrown into the spotlight as a promising new alternative energy due to Korea’s geography being suitable for development.

The advantages of marine bioenergy is that there is no need to worry about depletion. Also, it can be used continuously once developed, and large-scale development is possible. Lastly, its impact on the environment is minimal. It will be great if Korea would be able to utilize its geographical advantage as a peninsula and develop the environment-friendly alternative energy in the future!
