Description

technical field [0001] The invention belongs to the technical field of lead-acid batteries, and in particular relates to a lead-carbon battery negative electrode paste, a preparation method thereof, a lead-carbon battery negative plate and a lead-carbon battery. Background technique [0002] Energy and the environment are two major problems facing society today. In order to alleviate the energy and environmental crisis, my country is vigorously developing renewable energy such as solar energy and wind energy. However, the output power of this type of clean energy is intermittent and fluctuating, which cannot meet the load. With the help of battery energy storage technology, these deficiencies can be effectively made up for. At present, electrochemical energy storage is mainly divided into several types such as lead-acid batteries, nickel-metal hydride batteries, lithium-ion batteries and supercapacitors. Among them, lead-acid batteries have the advantages of rich raw material...
