Solid-state batteries are potentially safer, with higher energy densities. Solid-state batteries are found in pacemakers, and in RFID and wearable devices. Materials proposed for use as electrolytes include ceramics (e.g., oxides, sulfides, phosphates), and solid polymers. the mainstream type of) Li-ion batteries, such as flammability, limited voltage, unstable solid-electrolyte interphase formation, poor cycling performance, and strength.
For that reason, solid-state batteries can potentially solve many problems of liquid electrolyte (i.e. The solid electrolyte acts as an ideal separator that allows only lithium ions to pass through. Solid-state batteries can use metallic lithium for the anode and oxides or sulfides for the cathode, increasing energy density. Developments in the late 20th and early 21st century generated renewed interest in the technology, especially in the context of electric vehicles.
While solid electrolytes were first discovered in the 19th century, several issues prevented widespread application. All-solid-state battery with a solid electrolyte between two electrodes
