Abstract
An electrode configuration for a battery cell includes a positive electrode, a negative electrode, and a separator interposed between the positive electrode and the negative electrode. The separator includes an electrically conductive protrusion inhibiting layer and a first insulating layer interposed between and electrically insulating the protrusion inhibiting layer from one of the positive and negative electrode.
