Abstract

The invention provides a formula and preparation method of a high energy storage lead-acid battery lead paste and relates to the technical field of lead-acid batteries. The formula of a positive plate lead paste comprises the following raw materials: 7-8.5% of dilute sulphuric acid, 10.2-10.8% of deionized water, 0.2-0.4% of colloidal graphite, 0.8-2% of red powder, 0.06-0.09% of stannous sulfate, 0.05-0.08% of polyester staple fiber and the balance of lead powder; the formula of a negative plate lead paste comprises the following raw materials: 6.8-7.5% of dilute sulphuric acid, 9.8-10.8% of deionized water, 0.2-0.4% of acetylene black, 0.2-0.3% of humic acid, 0.8-1.0% of barium sulfate, 0.08-0.1% of barium stearate, 0.15-0.18% of sodium lignosulphonate, 0.06-0.09% of polyester staple fiber and the balance of lead powder. The battery prepared by the lead paste has the advantages of high initial capacity and long cycle life; and the overdischarge resistance and charge acceptance of the battery are higher than the standard requirements.

Description

technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to a formula of lead paste in the manufacture of pole plates of lead-acid batteries for electric bicycles and a preparation method thereof. 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 c...
