Samsung solid-state EV battery release date set to match Toyota's

Samsung's SDI division that is in charge with development and production of EV batteries, has created a dedicated team for solid-state battery commercialization. The scheduled launch appears to match Toyota's self-imposed solid-state battery release deadline of 2027 when the first electric Lexus with solid-state battery should hit the showroom floors.

The manufacturing advantages that Samsung banks on to achieve 2027 solid-state battery commercialization are numerous, as it has years of experience in manufacturing multi-layer ceramic capacitors (MLCC), which are now in high demand thanks to EV applications. This know-how has helped it produce solid oxide at high temperatures, whose stability makes it a prime candidate to serve as the oxide electrolyte used in solid-state batteries instead of the flammable liquid one in current EV batteries.

Samsung touted its solid-state battery as capable of "a longer battery life achieved by the company’s proprietary solid electrolyte and anode-less technologies." It now claims that it will be able to achieve over 900+ Wh/L by adopting sulfide-based electrolyte technology, the same approach that Toyota will take to bring its own solid-state battery to market.

Coincidentally, Samsung is gunning for the same 2027 commercial solid-state battery release, apparently buoyed by the results from a pilot production line it established at the Suwon research center earlier this year. Samsung's dedicated "dream" solid-state battery team is headed by Go Joo-young, a VP in its EV battery department, with the goal to "accelerate project speed with customers and expedite the commercialization of ASB through the new organization."

Speaking of customers, Samsung supplies EV batteries to juggernauts like General Motors, Stellantis, or BMW, and Hyundai will be getting its prismatic cells. While its partnership with Rivian fell through on industrial espionage worries, Samsung SDI scouted locations in Michigan and Illinois for a joint 40 GWh battery factory with Stellantis.

A true solid-state battery will be a game changer for the EV industry if it is made affordable, and the more competition form the ranks of Samsung and Toyota, the merrier.
