Problems solved by technology

However, this method has problems such as complicated packaging process, high cost, and difficulty in controlling the final shape of the battery packaging product.
This severely restricts the promotion and replacement of secondary batteries in many application fields of primary batteries.
[0005] On the other hand, for the external packaging of the secondary battery, many auxiliary structural devices need to be installed, which takes up a large space, resulting in a significant decrease in the overall volume energy density or mass energy density of the battery plus the packaging.

Abstract

The invention provides a constant voltage output structural member. The constant voltage output structural member comprises a protection plate, a constant voltage plate, an output terminal and an insulation elastic gasket, wherein a central hole is formed in the insulation elastic gasket, and a protruding part is arranged at the edge of the central hole. The constant voltage output structural member also comprises a rechargeable battery employing the constant voltage output structural member provided by the invention, wherein a battery core is arranged in a shell, a punching groove is formed in an opening end of the shell, the constant voltage output structural member is further sealed at the opening end of the shell, a positive electrode leading-out tab of the battery core is connected to the other end which a first resistor 9R1) and a VDD port of a protection integrated circuit (IC) are connected, a negative electrode leading-out tab of the battery core is connected to a GND port of the protection IC, the protection plate is arranged blew a groove position of the punching groove in the shell, the insulation elastic gasket and the constant voltage plate are sequentially arranged above the groove position of the punching groove in the shell, and a negative electrode output end of the constant voltage plate is in close contact with the shell. The rechargeable battery is novel in structure and is convenient to fabricate, the voltage output can be limited according to demands, and the market demand can be satisfied.

Description

technical field [0001] The invention relates to a constant voltage output structural part and a rechargeable battery using the same. Background technique [0002] With the development of secondary battery technology, the performance of secondary batteries has been rapidly improved, and its cost has also been greatly reduced, especially the high energy density and recyclable characteristics of secondary batteries, so it has been increasingly The wider the application. For example, rechargeable lithium-ion batteries in secondary batteries have become the main power supply batteries for mobile phones, notebook computers, and cameras, and in many traditional application fields of primary batteries such as remote controls, flashlights, toys, etc., secondary batteries are gradually becoming more and more popular. Primary battery replacement. [0003] However, compared with the primary battery, the secondary battery still has many inconveniences in use. The primary battery does ...
