A composite solid electrolyte ( 100 ) for lithium batteries can include a solid polymer ( 110 ), phyllosilicate nanoparticles ( 120 ) distributed in the solid polymer, and a lithium salt ( 130 ) distributed in the solid polymer. In one example, the composite solid electrolyte can be used in a solid state lithium battery cell ( 400 ) made up of composite solid electrolyte, an anode ( 420 ) containing lithium in contact with a first surface of the composite solid electrolyte, and a cathode ( 430 ) in contact with a second surface of the composite solid electrolyte. |
