Solid-state battery

Solid-state batteries are currently seen as a promising successor to the lithium-ion battery in electric vehicles. The idea is to replace the liquid electrolyte, which acts as the conducting medium between the two electrodes in a lithium-ion battery, with a solid one.

By eliminating the battery fluid, the cooling system is no longer necessary. Therefore, solid-state batteries are lighter and more compact than lithium-ion batteries and can have a higher energy density. This in turn promises a greater range.

The risk of fire in electric cars would also be reduced with the solid-state battery because the battery fluid in particular is highly flammable. A burning lithium-ion battery is difficult to extinguish.
