Abstract

The invention discloses an anode lead paste for a power lead-acid storage battery. The anode lead paste comprises the following constituents by mass: 1,000 parts of lead powder, 90-110 parts of deionized water, 70-100 parts of sulfuric acid solution with mass percentage of 50%, 0.6-0.9 part of synthetic fiber, 10-30 parts of barium sulfate, 0.5-3 parts of lignin, 0.5-2 parts of tin sulfate, 0.5-3 parts of lignin sulfonic acid and 5-20 parts of polyaniline. The invention simultaneously discloses a preparation method of the anode lead paste for the power lead-acid storage battery. By the anode lead paste for the power lead-acid storage battery and the preparation method thereof, the low-temperature performance of the power lead-acid storage battery can be effectively improved, and the problem of a short cycle life at a low-temperature state is solved.

Description

technical field [0001] The invention relates to a negative electrode paste of a power lead-acid battery and a preparation method thereof, belonging to the technical field of power lead-acid battery production and manufacturing. Background technique [0002] According to information released by the China Bicycle Association in 2012, the social ownership of electric vehicles in my country has increased to 142 million, and the number of electric vehicles per 100 households in developed cities has exceeded 30. The survey shows that more than 95% of electric vehicle power sources use lead-acid batteries . Lead-acid power batteries are regarded as the "heart" of electric vehicles and have become the focus of attention in the electric vehicle industry. There are problems with the safety and cost performance of lithium batteries. Power lead-acid batteries will remain the best for a long time in the future. The position of the power source. [0003] The power lead-acid battery is a ...
