The invention discloses negative electrode lead paste suitable for high and low temperature environments, and a preparation method thereof, and a lead-acid storage battery. The formula of the negativeelectrode plate lead paste comprises the following components in parts by weight: 100 parts of lead powder, 8-11 parts of sulfuric acid, 7-10 parts of deionized water, 0.04-0.06 part of high-strengthshort fiber, 0.1-0.2 part of lignin, 0.1-0.25 part of granular carbon black, 0.65-0.95 part of nano barium sulfate, 0.4-0.6 part of humic acid, 0.25-0.45 part of a surfactant, 2-4 parts of a carbon nanotube solution and 0.10-0.25 part of a hydrogen evolution inhibitor. According to the lead-acid storage battery produced by adopting the negative electrode plate lead paste formula, the high-temperature and low-temperature performances of the lead-acid storage battery are comprehensively improved, and the lead-acid storage battery has the advantages of long high-temperature service life and goodlow-temperature large-current discharge performance.

Description

technical field [0001] The invention belongs to the technical field of accumulators, and in particular relates to a negative lead paste, a lead-acid accumulator and a preparation method which are suitable for both high-temperature and low-temperature environments. Background technique [0002] With the rapid development of lead-acid batteries and the automotive industry, users have increasingly stringent requirements on the performance of batteries, and higher requirements on the environmental adaptability of batteries. The application range of traditional automotive lead-acid batteries is between -30°C and 60°C, and the battery life decays quickly when used at too high or too low ambient temperature. In the prior art, although there have been some studies on batteries used in low-temperature environments, there have been no batteries that meet the requirements of high-temperature and ultra-low-temperature environments. Long-distance commercial vehicles have a long mileage ...
