EV solid battery, Korea-Japan-Germany ‘3 leaders’

The battle for development of a "solid-state battery" among Korean, Japanese and German automakers is getting fierce.
Toyota Motor Corp. will open its first electric car with a solid-state battery by the early 2020s. Here, Hyundai Motor and BMW are challenging the development of all-solid-state batteries that can prevent the explosion. Alliances between major automakers and chemists and electronics companies and start-ups are also gaining momentum in order to take the lead in the solid-state battery field, which will become the `game changer` in the electric car market.
All solid-state batteries are solid-state, so it is the next-generation battery that can solve the danger of ignition and explosion of Li-ion battery using liquid electrolyte.
According to industry sources and the Nihon Keizai Shimbun on December 20, Toyota is expected to invest JPY 1.5 trillion (about KRW 14.5 trillion) in battery development and production of electric vehicles by 2030. Besides, Panasonic, which is a leader in the field of electric car batteries, has decided to speed up the development of all-solid-state batteries, the next generation of batteries. Toyota Akio President Toyoda and Kazuhiro Tsuga, president of Panasonic Corporation, announced on the 13th that they will develop the entire solid-state battery technology in Tokyo and manufacture the world`s top-quality `square battery`. This is because Toyota is behind in the development of EVs, so it is expected to create a new market with a square-shaped battery technology that differentiates it from a cylindrical battery. Using a square battery makes it easier to design an electric car and produce a variety of models. Toyota and Panasonic also decided to work on building a stable resource procurement system for batteries. We are also considering a wide range of collaboration including battery recycling and recycling.
BMW also competed in the development of a solid-state battery. BMW today announced that it has decided to jointly develop a next-generation all-solid-state battery with a longer life span and shorter charging time than a lithium-ion battery in partnership with US startup Solid Power. Solid Power is a battery specialist with a core team at the University of Colorado`s Boulder campus, and is now producing highly efficient lithium-ion batteries. BMW has partnered with SolidPower to accelerate the commercialization of solid-state batteries.
Domestic battery companies such as LG Chem and Samsung SDI are nervous about investment in aggressive pre-solid battery of Japan and Europe. Hyundai Motor is also raising its solid-state battery technology at its battery development team at the Namyang R & D Center. We are strengthening research and development to bring all solid-state batteries with charging time shorter than today`s lithium-ion batteries and 40-50% improvement in mileage by 2022. "We are developing lithium-ion lithium-sulfur batteries that have more than double the life of a lithium-ion battery," said Lee Ki-sang, chief executive officer of Hyundai Motor Environmental Technology Center. "This technology is in its infancy and it will be commercialized."
Meanwhile, a solid battery can be used as a pure battery space for battery cooling and securing safety, as well as short charge time and long mileage.
