Ito, Yasumasa; Banerjee, Sanjoy

A novel electrode current collector design that can improve performance and extend cycle life for rechargeable batteries based on metal electrodeposition is disclosed. The novel electrode current collector has a reduced effective surface area that can help to balance efficiencies between battery electrodes and to ensure non-uniform electrodeposition of metal onto the anode current collector during charge. One result is mitigation of internal short circuits that can cause a battery to fail prematurely.
