RESISTIVE POLYMER MEMBRANES FOR ENERGY STORAGE DEVICES

Systems and methods are disclosed for a battery that includes an anode, a separator between the anode and the cathode, a cathode, and a membrane coupled to the separator having a mixed electronic conductor and ionic conductor. A method may include casting a membrane onto a surface, dispersing carbon nanotubes in acetone to form a dispersion, adding a powder and dibutyl phthalate to the dispersion to form a polymer, and mixing the polymer. Another method may include casting a sheet of a composite, removing the sheet, and rinsing the sheet. Another method may further include casting a film, evaporating to form a dry film, and casting a mixture onto the dry film to form a bilayer membrane. Another method may further include casting a cathode, casting a CNT mixture onto the cathode, evaporating the cathode, and rinsing the cathode in ether.
