These seem like ones tested by GreatScott 7 years ago: https://youtu.be/kJXRyWQgOY4

    Same company, their newest cells are based on that tech, but with 7 years of advances, so 360Wh/kg. Which is about the same as most other top end Lithium-ion batteries, just solid-state rather than a liquid electrolyte.

    There is some specific reason why we don't use it? Or they last too long so companies don't want to sell them?

    They're brand new at that energy density. They just haven't made their way into many products.

    ProLogium is building a gigafactory in France.

    The newest batteries also seems to solve the charging issues, which was rather slow.
