The Evolution of EV Batteries

Before diving into the juicy details, it’s always helpful to cover the basics. Batteries are made up of 3 main components. The anode, or negative electrodes, the cathode, or positive electrodes and some type of electrolyte through which the electrodes travel to release chemical energy.

The first rechargeable battery, lead-acid battery, was invented in 1859 by a physicist named Gaston Plante. Lead dioxide was the cathode material used, and lead was the anode material with a liquid solution of sulphuric acid and water as the electrolyte. The materials were affordable and the battery was applied to many early models of EVs, including early models of the Tesla Model S.

Another widely used battery that came after the lead-acid battery is the nickel-metal hydride (NiMH) battery developed at the Battelle-Geneva Research Center in 1967. Nickel hydroxide was used as the cathode material while a hydrogen-absorbing alloy was used as the anode material. A liquid solution served as electrolytes. The research for NiMH batteries was extensive, and funded jointly by Daimler-Benz and Volkswagen AG. The batteries were also applied to many EV models such as the Toyota Prius, prior to 2015.

The Advent of Lithium-Ion Batteries

The introduction of lithium-ion batteries was a game-changer. Sony first introduced them in 1991, and today, most EVs have them, including the Tesla Model 3. The batteries consist of lithium-cobalt oxide cathodes, graphite anodes and the electrolyte is usually a solution of lithium salt and an organic solvent, though some automakers are experimenting with solid-state electrolytes.

Compared to its predecessors, lithium-ion batteries have the highest amount of stored energy and specific power, which is kind of like horsepower for electric cars. As a result of improved technology and lower costs, lithium-ion batteries are projected to make up 70 percent of the total rechargeable battery market by 2025, which will be worth roughly USD 112 billion.

Good as Gold

It is estimated that every 1 percent increase of EVs in the auto market will result in an additional 70,000 tons of lithium demand LCE per year.

In 2016, Australia topped the list for the most lithium produced with 14,300 metric tons. China and Zimbabwe are also top contenders producing 2000 and 900 metric tons in 2016, respectively. Then, there are the South American countries of Argentina, Chile, and Bolivia, also referred to as the “lithium triangle,” and home to 75 percent of the world’s lithium supply.

Does that mean the world has enough lithium to fuel the cars of tomorrow? The answer is yes, but there aren’t enough mines to produce them. In order to prevent environmental damage and the exploitation of unprotected workers, lithium producers have to get smart about lithium mining and production.

POSCO’s Lithium Production  

Starting in 2010, POSCO and the Research Institute of Industrial Science & Technology (RIST) teamed up to develop a chemically based lithium extraction technology. The innovation cut down extraction time from up to 18 months down to between 8 hours and 1 month, delivering a purity rate of 99.9 percent. The recovery rate of lithium also increased to over 80 percent. POSCO is the world’s first corporation to commercialize the technology.

It’s also at the heart of the lithium triangle. POSCO currently operates facilities in Chile’s Maricunga Salt Lake, Argentina’s Cauchari Salt Lake and Argentina’s Pozuelos Salt Lake, which alone will boost POSCO’s annual lithium production to 2,500 tons. POSCO also opened its first battery production plant in Korea earlier this year.  

The future of EVs is promising thanks to advancements being made in electric batteries, and there’s a lot at stake for the health and well being of future generations. Increasingly, the availability and costs of EV battery materials will play a vital role in market outcomes and widespread EV adoption. It is vital for companies like POSCO to provide abundant, sustainable and cost-friendly EV battery materials so automakers can continue to enhance the batteries of tomorrow’s cars.

Why Should People Care About Autonomous Transportation?

Autonomous transportation is emerging across the world, from personal vehicles to Tesla’s proposed semi trucks that drive in convoy with a lead vehicle handling autonomous follow trucks. Intel is also planning to test a fleet of one hundred autonomous cars and Hyundai’s planning to showcase its self-driving technology at the biggest winter sports event of 2018.

While many have heard of self-driving cars and other road-based vehicles, it may come as a surprise to learn just how far technology has advanced in autonomous transportation. The Swiss bank UBS, suggests that autonomous airplanes could be in place by 2025, a feat that would save airlines $35 billion a year. Clearly, the benefits are drastic and it is becoming essential for companies to invest in making autonomous travel work.

Even further into the future, companies like Next Future Transportation are envisioning pod travel, through which individual vehicles will autonomously transport people from point A to point B.

No matter the type, the economic impact of autonomous transportation technology is unavoidable. Boston Consulting Group expects that the driverless car market will be worth $42 billion by 2025 and $77 billion by 2035, and IHS suggests driverless car ubiquity will hit around 2050.

In terms of what these automated vehicles offer to the public, the Eno Centre for Transportation reports that if 90 percent of American roads were autonomous, accidents would drop from 6 million a year to 1.3 million; deaths would fall from 33,000 to 11,300. Add in better traffic conditions, higher fuel efficiency and extra time gained from not driving, and it’s easy to see why companies are taking notice of this tech sector.

Who is Investing in Autonomous Transportation?
Autonomous transportation entails investment from various industries from materials to technology, and major players are making early moves. Tesla is a good example of a specialty vehicle company determined to see autonomous transportation become a worldwide reality.

Big names in traditional transportation are also jumping aboard. General Motors purchased Cruise Automation, and Ford has invested in an AI startup, Argo AI. Audi has created a subsidiary, the SDS Company, focused on self-driving technology, and BMW has formed an alliance with Intel and Mobileye.

There are also auto suppliers getting into this market, such as Magna, a supplier that is manufacturing vehicles as well as providing the parts to help more traditional companies jump into automated vehicles.

Tech giants like Microsoft are getting involved, too, collaborating with automakers to include their own technology in self-driving vehicles, as well as to research and develop automated transportation technology.

Whether companies are involved in creating the actual vehicles that will be automated, providing security and safety features, pursuing further research, or providing the materials needed to create these vehicles of the future, it is safe to say that this industry is growing rapidly.

Autonomous Transportation and the Steel Industry
A shift toward autonomous transportation is good news for the steel industry. At first glance, it seems steel consumption will decrease as fewer car accidents will lead to less demand for repair parts and more room to use other materials for aesthetic purposes. However, demand for high-strength, premium steels that are highly sought after in traditional cars will continue to increase.

Materials like POSCO GIGA STEEL provide greater strength and safety for automated vehicles, an important consideration when one considers a road full of cars driving themselves. While people may no longer be behind the wheel, they will want to know that their cars, and the cars around them, are made to the highest safety standards. Safety regulations for traditional cars are only getting tougher, and that won’t change with autonomous vehicles.
