"Toyota's next-generation electric vehicle batteries could vastly improve the driving range and charging speeds compared to today's packs. The company is reportedly working on cells that can last four decades and be reused multiple times during that period. The aging will happen with minimal energy degradation, the company claims. Writing about solid-state batteries feels like waiting for a train that's always five minutes away, but it never actually arrives."
"At the recently concluded Japan Mobility Show, Toyota said that its solid-state batteries are designed to last 40 years. If that's true, that would be about 2.7 times the average age of a passenger vehicle in the U.S. as of 2025, which now stands at 14.5 years according to the Bureau of Transportation Statistics. Keiji Kaita, the president of Toyota's Carbon Neutral Advanced Engineering Development Centre, explained these goals to the Australian news outlet Car Expert."
Toyota is developing next-generation solid-state batteries intended to last about 40 years while retaining roughly 90% capacity, far exceeding current lithium batteries targeted at about 10 years and 90% capacity. The cells are described as reusable multiple times with minimal energy degradation and could improve driving range and charging speeds. Upfront costs may be higher, but longer lifespan could offset lifecycle expenses. A 40-year battery would outlast the average U.S. passenger vehicle age by roughly 2.7 times. Solid-state commercialization has lagged industry promises, and real-world mass-market applications remain limited despite recurring bold claims.
