Problems solved by technology

The current internal formation process requires acid pumping after charging is completed, and then rests for 24 hours to ensure battery voltage stability and eliminate concentration polarization. The resting time of this process is too long to meet production needs, so this problem is solved. it becomes very necessary

Abstract

The invention aims to provide a free-standing internal formation charging process for a storage battery. Through the adoption of the internal formation process in which charging is performed for six times and discharging is performed for four times, an original acid extraction step is advanced to the time after the fifth charging, so that the storage battery is unnecessary to stand for 24 hours, battery quality is guaranteed while production efficiency is improved, in addition, concentration polarization can be eliminated, and voltage stability can be ensured.

Description

technical field [0001] The invention relates to the field of accumulator manufacturing, in particular to a process for charging an accumulator without static internalization. Background technique [0002] Compared with tank formation, battery formation has many advantages. Its technological process simplifies the processes of plate washing, drying, battery replenishment, and tank formation, such as loading, welding, and sheet removal. A lot of man-hours and energy are saved, and there is no need to purchase formation tank equipment and acid mist prevention equipment, and the battery cost can be reduced to a certain extent. Moreover, the plate is not easily polluted by impurities, which can reduce battery self-discharge, and the battery quality can be better controlled. Therefore, battery formation is worth promoting, and formulating a reasonable battery formation process is the key to battery formation. The formation power is one of the main factors affecting the battery fo...
