Abstract: The present application provides a rechargeable battery including a battery case and a battery cap coupled to the battery case. The battery cap includes a conductive cap plate; a first electrode electrically connected to the cap plate; a second electrode insulatively connected to the cap plate, the second electrode being in electrical connection with one end of a conductive plate for securing the second electrode to the conductive cap plate; and a conductive turnover component in electrical connection with the conductive cap plate, the turnover component being initially separated from the conductive plate and capable deforming to contact other end of the conductive plate due to high pressure in the battery case, so as to short-circuit the first electrode and the second electrode.

Abstract: Provided is a lithium ion battery including a battery can, a battery core received in the battery can, electrolyte filled in the battery can, and a battery cover assembled to the battery can. The battery can or the battery cover is provided with a pressure relief valve, and the pressure relief valve is coupled with a mesh cover defining a number of through holes therein. According to the present invention, when thermal runaway occurs to the lithium ion battery, the pressure relief valve breaks timely. Only gases and electrolyte vapor can pass through the mesh cover. Solid particles cannot pass through the mesh cover. Therefore, ignition of the flammable gases, the electrolyte vapor and the high temperature solid particles in the surrounding air afar from the pressure relief valve is avoided and the safety performance of the lithium ion battery can be improved remarkably.
