Abstract

The invention discloses lead acid storage battery positive electrode lead paste, and belongs to the technical field of lead acid storage battery manufacturing. The lead acid storage battery positive electrode lead paste is prepared from lead powder, sulfuric acid, water, short fiber, sodium perborate, sodium pyroantimonate, red lead and titanium black. Besides the ingredients of the lead powder, the sulfuric acid, the water and the short fiber, the lead acid storage battery positive electrode lead paste also comprises the effective ingredients of the sodium perborate, the red lead, the titanium black conducting ceramic materials and the like. The hole shape and the porosity are maintained by a lead acid storage battery assembled in such a way in the charging and discharging process; the positive electrode active ingredients have high forming performance and active ingredient utilization rate; high capacity is realized during high-rate discharging; the network structure of the positive electrode active substances is stable; the early stage capacity of the battery can be increased; the early capacity attenuation of the battery can be prevented; meanwhile, the hydrogen separation potential of the battery is obviously reduced.

Description

technical field [0001] The invention relates to the technical field of lead-acid storage battery manufacturing, in particular to a lead-acid storage battery anode lead paste. Background technique [0002] Lead-acid battery has a history of more than 150 years since it was invented by Plant in 1859. The technology is very mature and it is the most widely used chemical power source in the world. Although new batteries such as nickel-cadmium batteries, nickel-metal hydride batteries, and lithium-ion batteries have been introduced and applied in recent years, lead-acid batteries still rely on high-current discharge performance, stable voltage characteristics, wide temperature range, and large single-cell capacity. It can charge and discharge hundreds of cycles, good storage performance (especially suitable for dry charge storage), high safety, rich and renewable raw materials, low price and other advantages, in most traditional fields and some emerging fields application field,...
