    Abstract: An electrochemical storage cell (300) comprises a core and a rectangular shell (305) that receives the core (200) snugly therein. The rectangular shell (305) has first and second open ends. A first end cap (335) is used to close the first open end. An anode terminal extends through the first end cap (335) from an interior portion of the electrochemical storage cell (305) to an external portion thereof. A first gasket (1405) is secured within the rectangular shell (305) between the first end cap (335) and the core (200) to resiliently hold the core (200) away from the first end cap (335). A second end cap is used to close the second open end. A cathode terminal extends through the second end cap from an interior portion of the electrochemical storage cell to an external portion thereof. A second gasket is secured within the rectangular shell between the second end cap and the core to resiliently hold the core away from the second end cap.

    Abstract: A stacked lithium-ion rechargeable battery comprises a plurality of stacked positive and negative electrode couples forming a battery core, each of said couple having a negative electrode, a positive electrode, a separator, and non-aqueous electrolyte, all encased in a battery case. The core is secured by a clamp case and said clamp case is encased in a battery shell. There are thin neck parts (or conducting tabs) extending from the base plates of the positive and negative electrodes to form the current collectors of the positive and negative electrodes. The positive electrodes and negative electrodes are arranged such that the two current collectors are located on the two opposite ends of the core. The current collector at each end of the core is clamped by a clip and connecting to the respective positive and negative terminals. This stacked lithium-ion rechargeable battery has a relatively low impedance, high discharge rate and high safety performance. The reusable rate of this battery is high after the battery short-circuits.
