Cooling treatment process after solidification of raw plate of lead-acid battery

Abstract

The invention discloses a cooling process for a green pole plate of a lead-acid storage battery after curing, and aims to overcome the defects that the cooling time is long after the pole plate of the storage battery is cured and a lattice structure between an active substance on a surface of the pole plate and a grid is not stable so as to improve defective rate of the pole plate, and the surface of the pole plate is easy to carbonize so as to improve the formation difficulty of the pole plate and reduce the capacity and the cycle lifetime of the battery. The cooling process comprises the following steps of (a) placing the green pole plate which is cured just now in a curing chamber under a normal-temperature environment for normal-temperature cooling for 0.5-1.5 hours; (b) performing temperature reduction on the curing chamber placed with the green pole plate, adjusting a temperature to 5-10 DEG C, simultaneously blowing air by a fan, and controlling time for 2-3 hours; and (c) placing the green pole plate in the curing chamber under a room-temperature ventilation environment for 0.5-1 hour, wherein pole separation and brush can be performed.

Description

technical field [0001] The invention relates to a production technology of battery pole plates, more specifically, it relates to a cooling treatment process after solidification of lead-acid battery raw pole plates. Background technique [0002] At present, lead-acid batteries are used in a wide range of fields, such as electric vehicles, electric road vehicles, telecommunications, electric power, portable equipment, energy storage, medical equipment and other fields. The pole plate is an important part of the lead-acid battery. In the current production process of the pole plate, especially in the process of sorting, weighing, and wrapping, it will cause the scrapping of the pole plate and a large amount of lead powder on the surface. The utilization rate of the pole plate increases the difficulty of job defense. After the battery plate is coated, it needs to be acid-drenched and rolled, which can increase the amount of lead paste on the plate, increase the strength of the...

Problems solved by technology

However, if the cured plates are not handled properly during the summer, the amount of dust in the actual production workshop will increase, and the scrap rate of the plates will remain high, whether it is the difficulty of the dust affecting the occupational defense or the scrap rate of the plates. The high level is an urgent problem to be solved at the present stage, especially in the high temperature and high humidity environment in summer, a small amount of lead carbonate particles are formed on the surface of the reaction surface between the plate and carbon dioxide in the air, which affects the battery formation process, making the formation of the plate more difficult. Large, the battery capacity is reduced, resulting in the performance of the battery product not meeting the requirements

Eventually lead to a series of problems such as poor consistency and short life of the battery
