Abstract

The invention belongs to a rapid curing drying method for an energy source battery positive electrode plate. According to the method, a multi-section low-temperature and high-temperature mixing curing method is used for a storage batter positive electrode plate, wherein the low temperature-high temperature is used for the electrode plate curing drying environment at the early stage of the curing drying, the high temperature-high temperature is used for the electrode plate curing drying environment at the middle stage of the curing drying, and the uniform dewatering is used for the electrode plate curing drying environment at the late stage of the curing drying. According to the present invention, with the method, the rapid curing drying time of the positive electrode plate can be substantially reduced, and the advantages of simple, practical and convenient process, production time saving, cost saving, good practical effect, energy saving, consumption reducing, production efficiency improving, high battery cycle life, and good product quality.

Description

[0001] technical field [0002] The invention belongs to a method for fast curing and drying of an energy battery positive plate. Background technique [0003] Battery technology belongs to the new energy industry, and it is developing very rapidly in our country. The core that affects battery life is the battery plate, and the quality of the plate depends on the process control of the plate during the curing and drying process. The curing and drying of the plate is to put the paste-coated wet plate in a special curing room, and to cure and dry it under certain temperature and humidity conditions, so that the residual free lead in the lead paste is further oxidized into lead oxide and lead. Form basic lead sulfate; at the same time, the surface of the grid is corroded, and lead oxide is formed on the surface of the grid to combine with the lead oxide in the lead paste, thereby improving the bonding force and strength of the grid and the active material. [0004] The tra...
