Abstract

This invention refers to a process for making high power chargeable cell, which contains selecting material of cell, optimizing positive-negative current collection structure and improving electrode group. Said material contains negative electrode alloy powder, positive basal body material, positive electrode conductive agent, positive electrode spherical nickel hydroxide and diaphragm paper. The positive electrode current correction structure optimization is collecting current by nickel sheet and other metal net, the negative electrode current collection structure contains a round of sparkled nickel in bottom of steel shell and a O-shape rubber ring, the electrode group structure improvement is adopting holed nickel plated steel tape and holed metal net as basal body material of current collecting unit, positive electrode adopts sparkled nickel as base material.

Description

[0001] The invention relates to a manufacturing process of a high-power rechargeable battery, in particular to a manufacturing process of a high-power nickel-hydrogen rechargeable battery. 1. Background technology [0002] With the advancement of the modernization level of society, people have higher and higher requirements for rechargeable batteries, which are mainly reflected in the output of rechargeable battery power. To meet people's requirements, the internal resistance of rechargeable batteries must be reduced to achieve charging. The high current discharge of the battery, in order to achieve this performance, there are mainly the following methods: the positive and negative electrodes are surface welded with nickel sheets; the positive and negative electrodes are used for current collection; the positive electrode is surface welded, and the negative electrode is metal. The net is spot welded, etc. However, the above methods must be welded to the surface or placed on th...
