Abstract

The invention discloses a production process of a temperature-resistant lead-acid storage battery. The production process comprises the following steps of: S1, putting a plurality of cork blocks into the side wall and the bottom of a battery protection shell mold, and manufacturing a battery protection shell through an injection molding process; S2, putting at least one cork block is into a battery protection cover mold, and manufacturing a battery protection cover through an injection molding process; S3, putting a battery into the battery protection shell; S4, adding cork powder into the battery protection shell and compacting the cork powder; S5, installing the battery protection cover on the battery protection shell in a sealed mode through epoxy resin glue, and manufacturing a temperature-resistant lead-acid storage battery through drying and hardening. Aiming at the technical problems of insufficient discharge capacity and short service life of an existing lead-acid storage battery, the invention provides the production process of the temperature-resistant lead-acid storage battery, which can increase the impact strength of the battery shell and improve the internal heat preservation effect of the lead-acid storage battery in extremely severe environments (high temperature and low temperature).

Description

technical field [0001] The invention relates to the technical field of accumulators, in particular to a production process of a temperature-resistant lead-acid accumulator. Background technique [0002] At present, most lead-acid batteries in the industry use battery shells made of PP, PE or ABS materials, which have low impact strength and are greatly affected by high and low temperatures. The equipment is easy to cause harm; the current lead-acid batteries are generally used in the environment of -20-50 ℃, when the ambient temperature is lower than -20 ℃, the discharge capacity and charging capacity of the battery are obviously insufficient; with the passage of time, the battery The side walls and the top will gradually expand, and the expansion will be more serious in a high-temperature environment, resulting in shortened battery life. [0003] The main defect of existing scheme is: [0004] 1) When the lead-acid battery is used at low temperature, the discharge capacit...
