Abstract

The invention provides a high-temperature-resistant lead-acid storage battery. The lead paste of the positive plate includes the following components: lead powder, red lead, short conductive fibers, nano solid solution, deionized water, colloidal graphite, crosslinking agent, diisoperoxide Propylbenzene, di-n-butyltin dilaurate. The positive plate of the high-temperature-resistant lead-acid battery in the present invention can reduce the loss of water in the use process of the lead-acid battery at high temperature, and the active material of the positive plate lead paste forms a structure similar to reinforced concrete, which improves the activity of the positive plate lead paste The binding ability and strength of the material; it inhibits the phenomenon of muddying and falling off of the active material of the positive plate at high temperature. The combination of the two makes the cycle life and high-temperature float life of the lead-acid battery significantly improved under high-temperature conditions, and the capacity decay rate is significantly reduced, making it suitable for use in high-temperature environments.

Description

technical field [0001] The invention belongs to the technical field of lead-acid storage battery manufacturing, in particular to a high-temperature-resistant lead-acid storage battery and a preparation method thereof. Background technique [0002] In the past ten years, valve-regulated sealed lead-acid battery technology has achieved great development and has been widely used in the communication industry, which plays an important role in the rapid development of the communication industry. In order to achieve a low-carbon economy and implement sustainable development, it is required to reduce the air-conditioning configuration in the computer room, reduce the frequency of air-conditioning use, increase the ambient temperature of the lead-acid battery, and reduce the pressure on the operating cost of the base station. [0003] At present, the performance of lead-acid batteries cannot meet the requirements. The energy consumption of air conditioners in communication base stat...
