Solid-state cells promise faster recharging, better safety, and higher energy density. They replace the liquid electrolyte in today’s lithium-ion cells with a solid separator. Honda, Toyota, and ...

Solid-state battery technology is seen as something of a holy grail for the EV industry and the potential advance has ...

Solid-state batteries offer a lot of benefits over their liquid brethren, with some major drawbacks, but one of those drawbacks may have been circumvented.

Solid-state batteries can be fully charged more quickly. Crucially, though, solid electrolytes are less dense, so a solid-state battery can be smaller and lighter than its lithium-ion competitor.

Put simply, solid state batteries have the potential to be smaller, lighter, less volatile, and more energy-dense than existing “liquid” batteries, which has huge implications for electric cars.
