【Abstract】 Polymer electrolytes with better performance are demanded in the development of polymer lithium ion batteries; therefore many attentions have been paid to solvent-free polymer electrolytes. There are three kinds of solvent-free polymer electrolytes: (1) coupled systems represented by the complex of modified polyethylene oxide and lithium salt; (2) decoupled systems with distinct conductive mechanisms; and (3) single-ion conductors with reduced anion mobility. Their development in recent years is reviewed, and special attention is paid to decoupled systems and single-ion conductors.更多还原
