Abstract

The invention discloses negative plate lead paste for a lead-acid battery. The negative plate lead paste comprises the following components in percentages by weight: 75-80% of lead powder, 2-6% of lead oxide, 0.05-0.1% of conductive fiber, 1.2-3% of potassium sulfate, 7-10% of deionized water, 0.1-0.3% of bismuth meal and 7-10% of a sulfuric acid solution with the mass percent concentration of 45%. The cycle life of the lead-acid storage battery prepared by using the negative plate lead paste disclosed by the invention is obviously prolonged, the low temperature discharge performance of the lead-acid storage battery is obviously improved, the high current discharge performance is basically the same, the cost is not increased, and the negative plate lead paste is very suitable for industrial production and wide in application.

Description

technical field [0001] The invention relates to the technical field of storage battery production, in particular to a lead paste for a cathode plate of a lead-acid battery. Background technique [0002] Batteries for hybrid electric vehicles are a huge new market for the battery industry. Lead-acid batteries have great advantages when used in hybrid electric vehicles and electric vehicles. They are low in price, stable in voltage, high in safety performance, and have a good manufacturing base. The core component of the battery is the pole plate, which is composed of a grid and lead paste, so the performance of the pole plate directly depends on the grid and lead paste, and the quality of the lead paste depends on the lead powder used in the paste and sulfuric acid and additives used. The current polar plates still have the problems of low mechanical strength and poor electrical performance. Contents of the invention [0003] The object of the present invention is to pro...
