THE NOT SO FAR AWAY FUTURE !

In solid state batteries the liquid electrolyte is replaced by a solid electrolyte, this makes it an All-solid-state battery (ASSB). As the liquid electrolyte poses the most danger in terms of flammability, the solid-state battery is much safer. Solid electrolytes also are compatible with better performing anode materials such as silicon or lithium metal.

Lithium metal has about 10 times the specific capacity of the graphite that is typically used in lithium-ion batteries, increasing the energy density.

The three most researched solid-state batteries use electrolyte materials such as sulfide, oxide and polymers. These all have different metrics in terms of safety, production difficulty and performance.
