Abstract: A packing device for electrode sheets is provided in the present disclosure. The packing device is used for pasting tapes on a stack structure consisted of the electrode sheets to packing the stack structure. The packing device is included of a tape fetching mechanism, a couple of claws, a carrying mechanism and a positioning mechanism. The tape fetching mechanism is used for moving a tape and putting on the claws. The claws are arranged at interval and a gap is thereby formed between the claws. Each claw is included of a chamfer surface, and the chamfer surfaces are arranged at opposite sides of the gap. The carrying mechanism is used for loading the stack structure. The positioning mechanism is used to drive the claws and the carrying mechanism move related to each other.

Abstract: An electrolyte storage structure for a lithium battery made of a battery core having a stack with positive electrode plates, negative electrode plates and separating films, a battery core positive electrode welded with the positive electrode plate, a battery core negative electrode welded with the negative electrode plate, electrolyte, and a cup for receiving the battery core, positive electrode plate, the negative electrode plate and the electrolyte. The cup has a receiving space for accommodating the electrolyte core, the positive electrode plate and the negative electrode plate, and the electrolyte is disposed separately from the battery core. The electrolyte is released and flows into the receiving space for infiltrating the battery core before the battery is set to use. The battery core is infiltrated and saturated with the electrolyte. Then the saturated lithium battery undergoes following procedures of charging and activation to generate a finished lithium battery.

Abstract: A battery apparatus with a heat absorbing body includes a casing, a cell and a heat absorbing body. The casing includes a containing space, an anode and a cathode disposed at the exterior of the casing, and a cell and a heat absorbing body installed in the containing space. The cell includes an anode handle and a cathode handle connected to the anode and cathode respectively. The heat absorbing body is attached onto a surface of the cell and includes an upper soft film and a lower soft film sealed with the upper soft film, and a phase change material is filled between the upper and lower soft films, such that the phase change material can absorb or release large amounts of heat in a phase change process to maintain the cell operated at a lower and more stable operating temperature and extend the life of the battery apparatus.
