Abstract

The invention belongs to the technical field of lead accumulators, and specifically discloses a positive lead paste for AGM start-stop accumulators and a preparation method thereof. The positive lead paste contains the following ingredients in parts by weight: 70-90 parts by weight of lead powder, 0.01-0.1 polyester fiber, 0.01-0.1 glass fiber, 0-0.8 4BS seed crystal, 5-12 red lead, 6-8 sulfuric acid and Pure water 7-9. The positive electrode paste can greatly improve the cycle life of the AGM start-stop battery, especially the 50% DOD cycle life, and slow down the muddy failure of the positive electrode paste during the use of the start-stop battery.

Description

technical field [0001] The invention belongs to the technical field of lead storage batteries, and in particular relates to a positive lead paste for AGM start-stop storage batteries and a preparation method thereof. Background technique [0002] With the attention of various countries on climate change and the gradual improvement of people's awareness of environmental protection, the voice of reducing vehicle exhaust emissions is also getting higher and higher. Pollutants emitted by motor vehicles mainly include hydrocarbons (HC), nitrogen oxides (NOx), carbon monoxide (CO), particulates (PM) and other harmful substances, which will have a direct impact on global climate change, environmental pollution, and human health. Reducing vehicle exhaust emissions has basically become the common understanding of the world's major economies. [0003] The micro-hybrid idling start-stop car has obvious practical significance in terms of saving fuel, reducing greenhouse gas, and toxic ...
