Beschreibung
Zusammenfassung:	A composite polymer electrolyte for lithium batteries comprising ceramic particles with negative surface charge balanced by Li+ cations is disclosed herein. Optionally, the composite also contains lithium salt and/or solvent. The material is prepared by exposing oxide particles to a Li-containing solution at a pH greater than the isoelectric point of the oxide, isolating the solid from the solution, and drying.
