classification Material examples Performance
Polymer material Polyethylene oxide (PEO) based, polyvinylidene fluoride (PVDF) based, polyacrylonitrile (PAN) based, polymethyl methacrylate (PMMA) based, polyethylene (PE) based Good conductivity, light weight, good elasticity, easy film formation, to a certain extent, in line with the development trend of light, safe, efficient and environmentally friendly chemical power, but low ionic conductivity at room temperature
Inorganic material Traditional lithium phosphorus oxygen ( Li-PON) type solid electrolyte Good ionic conductivity (2 × 10-6S/cm), low electronic conductivity (< 102S/cm), excellent electrochemical stability
Inorganic material New: LISICON, perovskite, sodium superionic (NASISON), garnet-like, Li 3 N and derivatives, oxide glass, sulfide glass, Li 3 InX 6 Li 4 SiO 4 type The electronic conductivity is extremely low; the Li+ conductivity is good at the working temperature; the grain boundary resistance is very small or almost no; the chemical reaction with the electrode material does not occur, the chemical stability is good; the thermal expansion coefficient is comparable to that of the electrode material; High (>5. 5 V); not easy to deliquesce, environmentally friendly, easy to prepare and cheap
