Embodiment 1

[0035] Add 83.5kg of lead powder (containing 75% by mass of PbO) into the paste mixing machine. Add 0.08Kg of short fibers, 0.25Kg of carbon material, 0.67Kg of barium sulfate, and 0.42Kg of composite additives into the lead powder, stir and mix evenly, then quickly add 7.58Kg of RO water into the paste mixing machine, and mix with the lead powder Carry out wet mixing evenly, and then pour in slowly with a density of 1.35g / cm 3 (25ºC) sulfuric acid solution 7.5Kg, vacuumize during the mixing process, control the temperature of the mixing paste at 60ºC, stir evenly, cool down to 40ºC, and get the low temperature resistant high rate AGM start-stop battery negative electrode lead paste when the paste is released.

Embodiment 2

[0037] Add 83.7kg of lead powder (containing 79% by mass of PbO) into the paste mixing machine. Add 0.08Kg of short fiber, 0.17Kg of carbon material, 0.67Kg of barium sulfate, and 0.46Kg of composite additives into the lead powder, stir and mix evenly, then quickly add 7.75Kg of RO water into the paste machine, and mix with the lead powder Carry out wet mixing evenly, and then pour in slowly with a density of 1.35g / cm 3 (25ºC) sulfuric acid solution 7.17Kg, vacuumize during the mixing process, control the temperature of the mixing paste at 60ºC, stir evenly, cool down to 40ºC, and get the low temperature resistant high rate AGM start-stop battery negative electrode lead paste.

Embodiment 3

[0039] Add 83kg of lead powder (containing 76% by mass of PbO) into the paste mixing machine. Add 0.05Kg of short fiber, 0.25Kg of carbon material, 0.69Kg of barium sulfate, and 0.65Kg of composite additives into the lead powder, stir and mix evenly, then quickly add 8.21Kg of RO water into the paste machine, and mix with the lead powder Carry out wet mixing evenly, and then pour in slowly with a density of 1.35g / cm 3 (25ºC) sulfuric acid solution 7.15Kg, vacuumize during the paste mixing process, control the temperature of the paste to 60ºC, stir evenly, cool down to 40ºC, and get the low temperature resistant high rate AGM start-stop battery negative electrode lead paste when the paste is released.

Abstract

Low temperature-resistant high-rate AGM start-stop battery anode lead plaster and a preparation method thereof. The lead plaster includes: 83-85% of lead powder, 7-7.5% of a sulfuric acid solution, 6-8.5% of water, 0.04-0.08% of short fibers, 0.17-0.34% of a carbon material, 0.6-0.85% of BaSO4, and 0.15-0.65% of a composite additive. The anode lead plaster can improve dynamic receiving feature andcycle performance of an AGM start-stop battery on the basis of the advantages of long service life and durable cycle performance of the AGM battery assembled with the lead plaster, thereby greatly improving the comprehensive performance of the battery. The lead plaster can satisfy high-rate, long-life and charge / discharge performances of an automobile under partial charge status during start andstop, especially a brake energy recovery function for the automobile, thus reducing sulfation of interior of the battery and improving charge receiving capacity. The lead plaster greatly improves low-temperature start capability of the AGM storage battery and increasing cold-start power and improving the charge receiving capacity of the battery.

Description

technical field [0001] The invention belongs to the technical field of lead storage batteries, and in particular relates to a low-temperature-resistant high-rate AGM start-stop battery negative lead paste and a preparation process. Background technique [0002] Energy and the environment are major issues facing the current society. The demand for energy in various countries is increasing day by day. At the same time, the use of energy, especially oil, will greatly damage the ecological environment. Especially today, with the gradual popularization of automobiles, the pollutants carbon hydroxide (HC), carbon monoxide (CO), tiny particles and nitrogen oxides emitted by motor vehicle internal combustion engines seriously endanger the living environment of human beings, so reducing automobile exhaust emissions has become a The current common understanding of the economies of various countries. [0003] At present, the batteries in automobiles are mainly flooded start-up batteri...
