All Solid-State Li-ion Batteries

Abstract

Lithium-ion batteries (LIBs) are widely used as energy storage due to their high energy density compared to lead-acid batteries and other heavy-metal batteries. However, current LIBs use flammable organic solvents and conductive salts as electrolytes resulting in safety concerns. Replacement of liquid electrolytes with inorganic solid electrolytes can address these safety issues. This technology is called an “all solid-state LIBs” and can be applied over a wide range of temperatures and voltage. Although these batteries are very safe, the performance of a particular battery depends on the type of solid inorganic electrolyte used. Each electrolyte has advantages and disadvantages. Therefore, the choice of electrolytes for all solid-state lithium-ion batteries depends on the environment in which they will operate and the specific battery requirements.
