  • BATTERY WITH IMPROVED ENERGY DENSITY
    Publication number: 20240387959
    Abstract: The present disclosure is directed to a battery including an anode and a cathode. The anode may include an anode current collector and anode active material disposed on the anode current collector, the anode active material forming an anode body and an anode neck extending from an anode surface of the anode body. Moreover, the anode current collector may include an anode current collector tab extending away from the anode neck. The cathode may include a cathode active material disposed on a portion of a cathode current collector, the cathode active material forming a cathode body and a cathode neck extending from a cathode surface of the cathode body. The cathode neck may overlap with the anode neck.
