Abstract

The invention provides negative lead plaster of a lead-carbon battery and a preparation method thereof, a negative polar plate and a lead-carbon battery, which belongs to the field of the preparation of a lead-acid battery, and aims at solving the problems of the existing lead-carbon battery that the hydrogen evolution over-potential is low and the dehydration of the battery is severe in the circulating process. A hydrogen evolution inhibitor is added into the negative lead plaster of the lead-carbon battery, and the lead-carbon battery adopting the negative lead plaster as a raw material solves the problems of the short cycle life caused by low hydrogen evolution over-potential of the lead-carbon battery and the severe dehydration of the battery in the circulating process.

Description

technical field [0001] The invention relates to the field of lead-acid batteries, in particular to the negative electrode paste of lead-carbon batteries and [0002] Its preparation method, negative pole plate, and lead-carbon battery. Background technique [0003] With the increasing shortage of global oil resources and the large amount of greenhouse gas emissions causing adverse effects on the environment, countries around the world are vigorously developing new energy vehicles to solve this global problem. The specific energy and cycle life of lithium-ion batteries and nickel-metal hydride batteries can meet the requirements of power vehicles, but they are limited by safety and price factors, and it is difficult to apply them on a large scale in the short term. Traditional lead-acid batteries have good safety and low price, and have the prospect of large-scale application in new energy vehicles. However, due to the poor high-current performance and low specific energy of...
