JUST IN: A Chinese company just recharged an EV from 0 to 80% in 7.5 minutes.

Most people have no idea what this means.

Greater Bay Technology just rolled its first all-solid-state EV battery cells off a production line.

These cells hit 260-500 Wh/kg in energy density. That's about double what most EVs run on today.

And the company's targeting mass production in 2026.

Today's EV batteries use liquid electrolyte. It works. But it has limits:

- Degrades over time
- Fire risk (liquid = flammable)
- Slower charging
- Energy density caps out

This solid-state battery replaces the liquid with a solid material. Safer. Denser. Better in almost every way.

Imagine charging your car from 0 to 80% in 7.5 minutes.

By 2030 the standard global car will cost $10,000 and it will not use gas.

@FluentInFinance EV battery fires are not from the liquid. It is from thermal runaway and degradation of the lithium itself. The solid state batteries will have some similar risk if the temperature inside is not controlled.

@EricFielding @FluentInFinance The liquid electrolytes make fires worse by being very flammable. One of the reasons battery fires can be so hard to put out. That is something (some) solid electrolytes can help with.
