Ion exchange membranes as electrolyte to improve high temperature capacity retention of LiMn2O4 cathode lithium-ion batteries

A LiMn2O4 cathode lithium-ion battery using lithiated ion exchange membranes swollen with organic non-aqueous solvent as the electrolyte to overcome capacity fading at high temperature is first demonstrated, and shows very good capacity retention compared with conventional lithium-ion batteries using liquid electrolyte.
