Toyota is one of several mainstream car makers investing in the development of SSB technology, which has long been viewed as a crucial next step for electric vehicle development, with its potential to significantly reduce the weight and size of battery packs while increasing performance.

 

SSBs are much more energy dense than the lithium ion batteries widely used in EVs today so allow for much longer ranges while occupying the same physical footprint - and are therefore key to reducing the height of EVs.
