Abstract

The invention discloses a rapid curing process of a battery plate. The rapid curing process comprises the following steps: stage 1: the temperature is 60 to 65 DEG C, the humidity is 95% to 100%, and the time is 0.5h to 1.0h; stage 2: the temperature is 60 to 65 DEG C, the humidity is 90% to 95%, and the time is 0.5h to 1.0h; stage 3: temperature is 70 to 75 DEG C, the humidity is 85% to 90%, and the time is 0.5h to 1.0h; stage 4: the temperature is 80 to 85 DEG C, the humidity is 80% to 85%, and the time is 1.0h to 2.5h; stage 5: the temperature is 70 to 75 DEG C, the humidity is 85% to 90%, and the time is 0.5h to 1.0h; and a drying stage: the temperature is 80 to 85 DEG C, the humidity is 0%, and the time is 1.0h to 4.0h. The scheme of the invention greatly improves the production efficiency of plate curing and drying, realizes the continuous production of lead-acid battery plates and assembly, and the manufactured lead-acid batteries have good capacity and cycle life.

Description

technical field [0001] The invention relates to the technical field of storage batteries, in particular to a rapid curing process for storage batteries. Background technique [0002] With the intensification of the world energy crisis and the rise of a low-carbon economy, the production model of China's battery industry is undergoing tremendous transformation and upgrading. The new production technology will gradually replace the old production technology. At present, high-tech complete sets of wire mesh production lines, continuous casting and rolling production lines, and automatic material conveying systems have gradually emerged, and advanced high-automation, complete sets, and systematic production models are emerging. [0003] In the manufacturing process of lead-acid batteries, the curing of green plates is a key process, and it is also one of the processes with the longest production cycle. At present, the common curing process time is usually between 60h and 90h; t...
