MULTI-LAYER BATTERY CONFIGURATIONS

Abstract:

Rechargeable battery cells according to embodiments of the present technology may include a housing including a first conductive segment operable at anode potential, and a second conductive segment operable at cathode potential. The housing may include a gasket positioned between the first conductive segment and the second conductive segment and configured to hermetically seal the housing. The battery cells may also include an electrode stack. The electrode stack may include a cathode current collector having a cathode active material extending across a first surface of the cathode current collector. The cathode current collector may be characterized by at least two pleats. The electrode stack may also include an anode current collector having an anode active material extending across a first surface of the anode current collector. The anode current collector may be characterized by at least two pleats.
