Abstract

The invention provides a negative electrode formula for improving the high-temperature performance of a lead-acid storage battery. The negative electrode formula comprises the following components in parts by weight: 100 parts of lead powder, 8-11 parts of dilute sulphuric acid, 9-13 parts of deionized water, 0.06-0.14 part of short fibers, 0.10-0.20 part of lignin, 0.3-0.45 part of humic acid, 0.05-0.1 part of a synthetic tanning agent, 0.8-1.2 parts of barium sulfate, 0.10-0.15 part of carbon black, 0.04-0.08 part of high-conductivity graphite, 0.08-0.15 part of a first hydrogen evolution inhibitor and 0.05-0.1 part of a second hydrogen evolution inhibitor. The method has the advantages that the mixture of the hydrogen evolution inhibitor and the humic acid is added into the formula of the negative electrode lead paste, and a certain proportion of humic acid is added into the negative electrode of a lead-acid battery, so that the sulfation phenomenon of the negative electrode can be effectively relieved; and the hydrogen evolution inhibitor of the hydrogen evolution overpotential and humic acid are compounded and then added into a negative plate of the lead-acid battery, so that the hydrogen evolution of the negative plate of the lead-acid battery is inhibited, the water loss rate is reduced, and the high-temperature cycle life of the battery is effectively prolonged.

Description

technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to a negative electrode formula for improving the high-temperature performance of lead-acid batteries and a preparation method thereof. Background technique [0002] Lead-acid batteries are used as the power supply of electrical equipment to provide power for the normal operation of the equipment. At the same time, they can also be used as a backup power supply to maintain the normal operation of the system when the main power supply of the electrical system cannot supply power normally. The excellent cost performance, large capacity and mature technology of lead-acid batteries make them stand out among many batteries. At present, the utilization rate of lead-acid batteries in the battery market has reached more than half. In recent years, the electronic information industry has developed rapidly, and the power communication industry has developed rapidly. Lead-acid batt...
