This document describes a new type of battery that is safer and longer-lasting than current lithium-ion batteries. The battery replaces the liquid electrolyte in lithium-ion batteries with a solid electrolyte made of a special type of ceramic that is non-flammable and allows ions to flow more freely. As a result, the new battery design eliminates the fire risk of traditional lithium-ion batteries and allows electric vehicles to drive longer distances on a single charge.
