    摘要： 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.

    摘要： A method and a device for controlling battery heating is disclosed. The method comprises: starting battery heating when conditions for starting battery heating are met; and stopping battery heating when conditions for stopping battery heating are met. The conditions for stopping battery heating include at least one of the following: (a) an absorbed energy Q of the battery reaching a predetermined energy QSET; (b) a time period Ti during which a discharging current I of the battery maintains constant (c) the discharging current I starting to decrease when a predetermined time period TSET is reached; and (d) a heating time period T reaching a predetermined maximum heating time period Tmax. The method and the device consider multiple conditions, for example, temperature, discharging current, battery State-of-Charge, heating time, etc. to determine when to stop battery heating, which may further enhance the operating efficiency and lifespan of the battery.

    摘要： A type of lithium ion secondary battery is disclosed; therein, the positive electrode 1 is formed by smearing an active material on the surface of an aluminum foil body, where said active material is compound oxide(s) comprising transition metals and lithium capable of absorbing and releasing lithium ions; the negative electrode 2 is formed by smearing an active material on the surface of a copper foil body, where said active material includes carbon material capable of absorbing and releasing lithium ions. Both the positive and negative electrodes have conducting strips acting as current conductors 6, 7. The positive and negative electrodes 1, 2 are in plate form and are alternately stacked on both sides of the belt-shaped separator 3 to form the electrode core 4. The separator 3 wraps around said electrode plates and separates the positive and negative electrodes 1, 2. This type of lithium ion secondary battery can effectively use the internal space of a battery shell, increase the battery's energy density, improve the large current discharge characteristic of the lithium ion secondary battery, the self-discharge ability, the battery's cycling capability and the battery's capacity.
