Abstract

A lead paste composition of a lead-acid battery anode relates to the technical field of a storage battery and is composed of following components based on weight percentage: 0.06-0.1 percent of tetroxide three lead, 0.04-0.09 percent of linear polyethylene, 10-10.5 percent of deionized water, 0.2-0.6 percent of grapheme, 0.6-2 percent of tertiary butanol, 4.5-8 percent of sulfuric acid and the balance of lead powder. Lead paste prepared according to a lead paste formula and a preparation method has high initial capacity and long cycle life after being prepared into the battery, and the over-discharging resistance performance and charging capability of the battery are far higher than standard requirement.

Description

technical field [0001] The invention relates to the technical field of storage batteries, in particular to a positive lead paste composition for lead-acid storage batteries. Background technique [0002] Lead-acid batteries have a history of 130 years. They have the advantages of reliable performance, mature production technology, and lower cost than nickel-metal hydride batteries and lithium batteries. The vast majority of current electric vehicles use sealed lead-acid batteries. The sealed lead-acid battery is to stack the positive and negative plates in the battery box, and the positive and negative plates are separated by insulating separators. When the electrolyte is charged into the battery box, the electrolyte and the positive and negative plates lead chemical reaction. When the battery is charged, the lead on the positive and negative plates that become lead sulfate releases the sulfuric acid component fixed in it into the electrolyte, and turns into lead and lead ...
