What are Solid-State Batteries?
Traditional lithium-ion batteries rely on a liquid electrolyte to facilitate chemical reactions between the anode and cathode. However, this electrolyte can be prone to leakage, explosion, and thermal runaway, making safety a major concern. Solid-state batteries, on the other hand, replace the liquid electrolyte with a solid material, such as glass or ceramic. This design change significantly improves safety, reduces flammability, and enhances overall performance.
