The EV Battery Supply Chain Has a Well-Kept Secret

Scientists are now playing with battery architecture and chemicals to make ambitious bets on what may ultimately lead to a more realistic path to mass electrification.

A futuristic bet?

Everyone is looking for new ways to get a piece of the global electric vehicle value chain. It’s no longer just car companies or battery firms, it’s the entire range of parts that make up batteries — from the chemicals that form each component to the wiring and everything in between. With all the noise around battery technology, though, it’s hard to wade through the futuristic bets to find the realistic ones. There is one country that could prove to be a happy hunting ground: South Korea.

While companies there took an early lead in cutting-edge EV battery technology, they were quickly overtaken, mainly by Chinese competitors that outdid them on scale and size. The likes of LG Chem Ltd.’s LG Energy Solution and Samsung SDI Co. have all shown promise but their global market share has waned. They may be set for a comeback.
