Abstract
A battery and a method of fabricating a porous membrane are disclosed. The battery includes an anode, a cathode, and a battery separator. The battery separator is positioned between the anode and the cathode and includes a macroporous substrate and a mesoporous silica thin film (MSTF) with perpendicular mesopore channels. The MSTF is positioned on the macroporous substrate. The method includes the following steps. A polymer film is formed on a marcoporous substrate. A MSTF with perpendicular mesopore channels is grown on the polymer film. The polymer film is removed to form the porous membrane.
