  • Patent number: 11870052
    Abstract: A rechargeable lithium-ion (Li-ion) battery employs a low temperature approach to battery manufacturing that forms charge material from kinetic energy of high velocity particles impelled into an aggregation such that bombardment of the particles against other particles in the aggregation forms a charge conveying structure. High velocity bombardment from a carrier gas nozzle accumulates an active charge material in a layered arrangement for the finished battery. Preparation of the particles, such as by ball milling or spraydrying, arranges particle agglomerations. The particle agglomerations, when impelled against other agglomerations or a current collector, forms a layer of cathodic, anodic or electrolytic battery material. The metallic binder conveys charge for mitigating or eliminating a need for a planar current collector underlying the sprayed layer. The resulting layers are suitable for battery operation, and are manufactured in an absence of any solvent drying or disposal.

  • Patent number: 11476541
    Abstract: A power supply device includes secondary battery cells disposed adjacent to each other and a separator that is interposed between the secondary battery cells adjacent to each other. The separator is made of a flexible material that has both a heat insulating property and restoring force such that the separator deforms when being pressed by each of the secondary battery cells and recovers an original shape of the separator. This configuration provides an improved heat insulating property between the secondary battery cells and prevents thermal propagation caused by thermal runaway. At the same time, this allows the separator to adapt to deformation of a secondary battery cell that has thermally swelled. In response to contraction of the swelled battery, the separator recovers its original shape to maintain a mechanical pressing force. This allows the power supply device to provide increased mechanical stability and maintain resistance to vibration and impact.

    Abstract: An assembly structure of a cover and a terminal for a power battery, including a cover and a terminal. The terminal includes a base and a post extending downwards from the base. The cover is provided with a mounting hole through which the cover is inserted against the terminal. A high-temperature resistant component is provided between the base and the cover, and a conductive block is riveted to a lower end of the terminal. A sealing member is provided between the conductive block and the cover. Different from the existing terminals, the present terminal is T-shaped. Therefore, current carrying area and capacity of the upper surface of the terminal are increased. Further, the riveting structure is provided at a bottom of the terminal, which can avoid the inaesthetic appearance of the terminal caused by soldering. The reliable assembly structure can avoid the terminal loosening and short circuit of the cell.
