1. An electrode configuration for a battery cell, comprising:
a positive electrode;
a negative electrode; and
a separator interposed between the positive electrode and the negative electrode, the separator comprising:
a protrusion inhibiting layer that is electrically conductive, the protrusion inhibiting layer comprising a lithium ion conducting material and a lithium protrusion growth inhibiting constituent interspersed within the lithium ion conducting material; and
a first electronically insulating layer interposed between and electrically insulating the protrusion inhibiting layer from one of the positive and negative electrode.
