Are electric car batteries liquid cooled?

With developing technology, solid-state batteries might become the preferred battery in electric vehicles. They are preferred for their rechargeability and safety.

Lithium-ion batteries are commonly used to build electric vehicles, but some automakers like BMW and Mercedes-Benz are starting to focus on solid-state technology.

Lithium-ion batteries run the EV market nowadays, but what are our other options? Nuclear energy could be one. Though there are issues to work out, nuclear energy could certainly be a viable way to power cars, with very little fuel required to produce huge amounts of power.
