Toyota wants to be the first automaker to offer a solid-state battery (SSB) in a production car. Many companies claim to be close, and some have even started real-world testing, so the race appears neck-and-neck. Toyota says its production application of SSBs could arrive in 2027, although 2028 sounds more likely, and it may be deployed in a high-power sports car, possibly an electric successor to the Lexus LFA.
