The major battery are frantically trying to get high-volume manufacturing of solid state batteries to work. Samsung is providing samples to car companies.[1] Volume production around 2027, probably at premium prices at first. CATL is also trying for 2027, and says that volume manufacturing is "challenging". Toyota says 2028. Many smaller companies also are making announcements.
So, not immediately, but it's past the vaporware stage.
