Abstract
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.
