High-rate high-capacity extremely-simple battery sealing cover, cylindrical battery and assembly process

Abstract

The invention relates to a high-rate high-capacity extremely-simple battery sealing cover, a cylindrical battery and an assembly process. The high-rate high-capacity extremely-simple battery sealing cover comprises a cover plate, a safety valve hole is formed in one side of the cover plate, the safety valve hole is sealed by a safety valve piece, an electrode hole is formed in the center of the cover plate, a pole is arranged in the electrode hole in a penetrating mode, an insulation sealing piece is arranged between the pole and the cover plate, the pole is connected with a first electrode through a first tab, an insulation support is arranged below the cover plate, an avoiding hole matched with the safety valve hole and the center hole is formed in the insulation support, and the cover plate penetrates through the insulation support to be fixedly connected with a second electrode. According to the high-rate high-capacity extremely-simple battery sealing cover, cylindrical battery and assembly process, the positive electrode and the negative electrode are integrated at one end, structural parts are saved, the structure is simplified, the cover plate serves as one electrode, overcurrent is larger, and high-rate charging and discharging are achieved.

Description

technical field [0001] The invention relates to the technical field of cylindrical batteries, in particular to a high-rate, high-capacity minimalist battery sealing cover, a cylindrical battery and an assembly process. Background technique [0002] A battery is an energy conversion and storage device that converts chemical or physical energy into electrical energy through reactions. A battery is a kind of chemical power source, which consists of two electrochemically active electrodes with different components, which are respectively composed of positive and negative electrodes. The two electrodes are immersed in an electrolyte that can provide media conduction. When connected to an external carrier, by converting internal chemical energy to provide energy. [0003] The structure of the current battery of the same type is basically the same, usually with tabs on both sides, and the positive and negative cover plates are a separate component. The capacity of the battery is ...

AI Technical Summary

Problems solved by technology

[0003] The structure of the current battery of the same type is basically the same, usually with tabs on both sides, and the positive and negative cover plates are a separate component. The capacity of the battery is inversely proportional to the internal structure of the battery. Therefore, when powering some high-power electrical equipment, multiple batteries of the same type are required for power supply, resulting in an increase in the number of batteries used and increased expenses.

In order to solve the above problems, in the prior art, a large-capacity battery with tabs is used, which is welded in the way of energy storage, but this structure can only be used for small current discharge, and the temperature rise is high during high current discharge, which cannot be guaranteed. Current battery life and safety
