Abstract: Systems, methods, and computer-readable media are disclosed for lithium-ion batteries with solid electrolyte membranes. In one embodiment, a battery cell may include a copper current collector, a first layer in contact with the copper current collector, the first layer comprising polyvinylidene fluoride, an anode comprising a first lithiated polymer binder configured to conduct lithium ions, where the first layer is disposed between the copper current collector and the anode, and a lithiated polymer electrolyte membrane in contact with the anode. The battery cell may include a cathode in contact with the lithiated polymer electrolyte membrane and comprising a second lithiated polymer binder configured to conduct lithium ions, a second layer in contact with the cathode, the second layer comprising polyvinylidene fluoride, and an aluminum current collector disposed adjacent to the second layer, wherein the aluminum current collector is a positive current collector.
