There are already solid state batteries available. But nobody buying it as lithium ion has surpassed it in terms of performance and power density.
Solid state battery is rapidly improving and catching up with lithium ion in terms of charging time, density and range. The Chinese and Japs (NIssan) are in the lead but the Chinese will hit the market first.

The EV revolution is nearer than you think
Six months ago I
wrote about the progress towards solid state batteries for cars. A lot has happened in six months, and its good news for those considering an EV.

The race is on
Every indication is that China car manufacturers will come to market first, even this year. With such a dramatic change in range, power and charging times, nobody can afford to come far behind. Chinese startup Farasis Energy, founded in Ganzhou, China, in 2009, is collaborating with Mercedes-Benz to commercialize advanced batteries. U.S. startup QuantumScape says the solid-state lithium metal batteries it’s developing will offer an energy density of around 400 Wh/kg. They say that its cells eliminate the charging bottleneck that occurs in conventional lithium-ion cells. QuantumScape’s advanced batteries will allow fast charging from 10 to 80 percent in 15 minutes. That’s still a far way off, but the Silicon Valley-based company announced in March that it had begun shipping its prototype Alpha-2 semi-solid-state cells to manufacturers for testing.
Solid Power, it’s also solid-state or bust. Solid Power, which aims to commercialize a lithium battery with a proprietary sulphide-based solid electrolyte, has partnered with major automakers Ford and BMW.
