The embodiment of the invention provides an integrated lithium battery and a packaging process thereof. The integrated lithium battery structurally comprises a shell of which the upper end is of an open structure; a battery cell accommodated in the shell and provided with a positive pole lug and a negative pole lug; and an injection molding part matched with the open structure and comprising a first end connected with the open structure and a second end far away from the open structure, wherein a PCM protection plate, a negative electrode cap, a positive electrode cap, a positive electrode nickel strap and a negative electrode nickel strap are packaged at the first end; the two ends of the positive electrode nickel strap are connected with the positive electrode lug and the PCM protection plate respectively, and the two ends of the negative electrode nickel strap are connected with the negative electrode lug and the PCM protection plate respectively; and one side of the positive electrode cap and one side of the negative electrode cap are connected with the PCM protection plate, and the other side of the positive electrode cap and the other side of the negative electrode cap extend to the outside of the second end. After the parts are assembled, a low-pressure injection molding process is adopted, and injection molding materials wrap the parts integrally, so that the integrated lithium battery is insulated, waterproof and sufficient in strength.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of lithium batteries, in particular to an integrated lithium battery and a packaging process thereof. Background technique [0002] As a daily necessities, AA batteries are widely used in various devices, such as toys, keyboard and mouse, remote controls, cameras, model airplanes, flashlights, electronic door locks, electronic clocks and other products. Batteries on the market mainly include disposable carbon batteries, alkaline batteries, and rechargeable nickel-manganese, nickel-chromium, and nickel-metal hydride batteries. With the increasing maturity of lithium battery technology and its advantages such as high voltage, high capacity, fast charging, recyclable use, and no memory effect, lithium rechargeable batteries gradually appear on the market and have a trend of popularity. However, due to its high energy density and its charging and discharging characteristics, lithium ba...
