Abstract

Embodiments disclosed herein generally relate to a microporous separator with a pore geometry that creates a low or no tortuosity architecture. In one embodiment, a battery cell may comprise of an anode layer, a cathode layer, and a separator layer positioned between the cathode layer and the anode layer. The separator layer may be comprised of one or more block copolymers. The block copolymers that make up the separator layer may be materials that self-align into a vertical nanostructure. The vertical nanostructures may allow ions within the battery cell to flow in a vertical path between the cathode and anode. This vertical path my create a low or no tortuosity environment within the battery cell.
