PM — Solid Electrolytes

Solid-state electrolyte can be categorized into solid polymer electrolyte (SPEs), inorganic solid electrolyte (ISEs) and composite polymer electrolyte (CPEs). SPEs are polymer matrix with Li salt dissolved. Poly(ethylene oxide) (PEO) is the most widely used SPEs.  Ion transport in PEO mainly occurs in amorphous phase, whereas the crystalline phase can be an obstacle for ion transport. ISEs have been widely used and studied for recent research. They have high ionic conductivity and mechanical strength but poor interfacial contact with electrodes.  ISEs can be classified into oxynitride (LiPON), NASICON, perovskite type, garnet type, lithium argyrodites and lithium sulfides. CPEs are composed...
