Title: External short-circuit protection device for lithium ion battery
Inventor: SHEN BINGJIE
IPC: H01M50/581
Filed: 2020-07-28
Abstract: Provided is an external short-circuit protection device for a lithium ion battery. The device comprises a cell and a busbar. A conductive tab is provided on the cell and adjacent to the busbar. Under the action of an external force, the busbar and the conductive tab come into contact or are separated, so as to establish or disconnect an electrical connection therebetween. The busbar is provided with an elastic bending portion. Under the action of a cover plate, the elastic bending portion of the busbar and the conductive tab come into contact or are separated, so as to establish or disconnect an electrical connection therebetween. The present invention uses a cover plate engagement post made of a heat-sensitive material to apply a pressure on the conductive tab and the busbar, so as to create a contact and an electrically connected circuit. Upon an external short circuit of a battery, the temperature at a pressure region rises rapidly, the engagement post softens or decomposes, eliminating the pressure, such that the conductive tab and the busbar are separated such that the circuit is disconnected, thereby cutting off the external short circuit of the battery, and protecting the battery so that it is safe to use.
