Separator and electrolyte composites include a porous self-supporting separator film between or adjacent one or two electrolyte films. The electrolyte films may contain a glyme or mixture of glymes, LiX salt and complexing agent, such as PEO. The porous self-supporting separator film may be used dry or wetted with a liquid electrolyte composition. Solid state batteries and electrochemical cells are disclosed that include the described separator and electrolyte composites in combination with an anode and a cathode.

Various embodiments of a battery assembly include a first housing shell, a second housing shell, an insulator and battery components. The first housing shell has a first perimeter side wall, a first housing bottom, and a first contact area on the first housing bottom. The second housing shell has a second perimeter side wall, a second housing bottom, and a second contact area on the second housing bottom. The second housing shell is disposed in the first housing shell with the second contact area opposing the first contact area. The insulator is interposed between the first housing shell and the second housing shell to effect electrical insulation between the first housing shell and the second housing shell. The battery components include an anode electrode, a cathode electrode, and a separator interposed between the cathode electrode and the anode electrode. The separator contains an electrolyte.
