Original Abstract Submitted

a battery that cycles lithium ions includes a lithium metal negative electrode, a positive electrode, a porous separator disposed between opposing facing surfaces of the lithium metal negative electrode and the positive electrode, and a composite interlayer disposed on the facing surface of the lithium metal negative electrode, between the lithium metal negative electrode and the porous separator. the composite interlayer includes a polymer matrix phase and a lithium salt distributed phase embedded in and distributed throughout the polymer matrix phase. the lithium salt distributed phase constitutes, by weight, greater than or equal to about 10% and less than or equal to about 50% of the composite interlayer.
