Ultimately, there probably will never be one battery technology used in all EVs, GM spokesperson Phil Lienert said. The type of batteries will be matched to the vehicle and the specific market where it’s sold. It’s similar to how automakers use different engines in various models and in different markets.
Then there might be improved lithium-ion batteries, maybe using silicon anodes or rocksalt cathodes, for mid-range vehicles, or perhaps solid-state lithium batteries will take over that class. Then there might be LiS or even lithium–air cells for high-end cars — or flying taxis. But there’s a lot of work yet to be done.
As energy shortage, climate change, and pollutant emissions have posed significant challenges to the sustainable development of the world automotive industry, the development of new energy vehicles, represented by electric vehicles (EVs), has received considerable attention from various countries and has gradually become a worldwide consensus .
The EV power battery system consists of hundreds or thousands of cells. The battery packing theory and structural integration, management systems and methods, and safety management and control technologies for power batteries are the keys to the application of EVs. 3.2.1. Power battery packing theory and structural integration
There’s a revolution brewing in batteries for electric cars. Japanese car maker Toyota said last year that it aims to release a car in 2027–28 that could travel 1,000 kilometres and recharge in just 10 minutes, using a battery type that swaps liquid components for solids.
Actual cars powered by solid-state batteries seem to be perpetually on the horizon: Toyota’s original target date for commercializing them in the early 2020s has now slipped to the late 2020s, for example. When it comes to batteries, “Toyota has said a lot of things in the last ten years, none of which have come through,” cautions Ceder.
