Abstract

The invention discloses positive paste prepared from 100% alpha-PbO lead powder, and relates to the field of lead storage battery manufacturing. The positive paste disclosed by the invention comprises the following components in parts by weight: 10000 parts of alpha-PbO lead powder, 1100-2000 parts of deionized water, 300-500 parts of sulfuric acid, 10-100 parts of graphite and 5-15 parts of short fiber. According to the positive paste, the consistency of the battery positive paste can be effectively improved, and the improvement of pole plate consistency can effectively improve the consistency of the battery; and after a storage battery is manufactured, the problem of pole plate softening after the battery is used can be overcome, and the service life of the battery can be effectively prolonged.

Description

technical field [0001] The invention relates to the field of lead storage battery manufacturing, in particular to a positive electrode paste prepared from 100% α-PbO lead powder. 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 fi...
