Abstract

The invention relates to the technical field of batteries, and particularly discloses a polymer battery as well as a mold and a method for encapsulating the battery. The polymer battery comprises an electric core, a guard plate which is linked with the electric core, and injection molding adhesive which is filled between the electric core and the guard plate. The polymer battery is manufactured through the following steps: firstly, performing spot welding on the electric core and the guard plate, then pasting adhesive paper on the guard plate for insulation, putting the electric core on which the adhesive paper is pasted into the mold for low-pressure injection molding, and finally performing mold opening to obtain the polymer battery. For the polymer battery disclosed by the invention, through direct injection molding at low pressure, the guard plate of the battery is sufficiently protected and supported, and the abuse resistance of the guard plate of the battery is strengthened. Through the direct injection molding, plastic adhesive frame materials are eliminated, so that the technology is simplified, the cycle of the mold is shortened, and the material cost and labor cost are reduced. Due to mold molding, the flatness and the consistency are ensured, and the appearance performance is improved. As a plastic adhesive frame is not needed to be additionally assembled, external force is not exerted to influence and the performance of the guard plate. The blank of the direct low pressure injection molding technology of a polymer electric core is filled.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a polymer battery and a mold for packaging thereof and a packaging method. Background technique [0002] The principle of polymer lithium-ion batteries is the same as that of liquid lithium, the main difference is that the electrolyte is different from liquid lithium. The main structure of the battery includes three elements: positive electrode, negative electrode and electrolyte. The so-called polymer lithium-ion battery means that at least one or more of the three main structures use polymer materials as the main battery system. In the currently developed polymer lithium-ion battery system, polymer materials are mainly used in positive electrodes and electrolytes. The positive electrode material includes conductive polymers or inorganic compounds used in general lithium-ion batteries. The electrolyte can use solid or colloidal polymer electrolytes, or organic electrolytes. ...
