Problems solved by technology

However, lead batteries have the fatal flaws of poor low-temperature performance and short life. With the further maturity of lithium-ion batteries and metal hydride nickel battery technology and the further reduction of product prices, lead-acid batteries are likely to gradually fade out of electric drive vehicles. market
The key to the above-mentioned defects of lead batteries lies in the imperfect and unreasonable composition and ratio of the active material of the battery plate, which urgently needs to be researched and improved.

Abstract

The invention discloses an active material of a lead storage battery plate. An anode active material comprises the following components by weight: 100kg of lead powder, 0.01 to 2kg of conductive fiber, 0.1 to 5kg of metallic oxide, 0.1 to 2kg of conductive carbon material, 0.01 to 1kg of sodium carboxymethyl cellulose and 1 to 15kg of diluted sulfuric acid; and a cathode active material comprises the following components by weight: 100kg of lead powder, 0.01 to 2kg of conductive fiber, 0.1 to 5kg of conductive carbon material, 0.1 to 0.6kg of barium sulfate, 0.2 to 1kg of humic acid, 0.01 to 0.1kg of lignin and 1 to 15kg of diluted sulfuric acid. The components and ratio of the active material are improved and optimized, and the active material comprises various carbon materials, so a super lead storage battery consisting of the plate made of the active material has high low-temperature performance, high rate charge and discharge performance and long charge and discharge cycle life, and particularly has strong market competition advantages when applied to electrically-driven vehicles.

Description

technical field [0001] The invention relates to an active material of a pole plate of a super lead storage battery, which belongs to the field of pole plates of a lead storage battery. Background technique [0002] In recent years, as the price of oil has risen again and again. The boom in the development and use of electric vehicles has become unstoppable. At present, it is actually used as the core component of the driving vehicle-batteries include lithium-ion batteries, metal hydride nickel batteries, lead-acid batteries, etc. Among them, lead-acid batteries with mature technology and moderate prices occupy an absolute proportion. However, lead batteries have fatal defects of poor low-temperature performance and short life. With the further maturity of lithium-ion batteries and metal hydride nickel battery technology and the further reduction of product prices, lead-acid batteries are likely to gradually fade out of electric drive vehicles. market. The key to the above...
