Abstract

The invention discloses a negative electrode plate material of a tubular lead-carbon battery. The negative electrode plate material is prepared by mixing the following raw materials in parts by weight: 100 parts of lead powder, 8-14 parts of sulfuric acid, 0.7-1.8 parts of barium sulfate, 0.5-10 parts of nano capacitance carbon, 0.1-1 part of nano conductive carbon fibers, 0.5-5 parts of graphene, 0.1-5 parts of expanded graphite, 0.1-2 parts of humic acid, 0.1-1 part of polyester fibers, 10-20 parts of water, 0.1-2 parts of lignin and 0.1-1 part of barium stearate. The negative electrode plate material has the technical effects that the conductive carbon fibers dispersed in a negative electrode plate play a role in a conductive framework; the activated carbon is introduced into the negative electrode plate, so that the sulfation phenomenon of the negative electrode plate is suppressed; meanwhile, a super capacitor is formed in the battery, so that the circulating performance of the battery is greatly improved. In a conclusion, the specific energy of the battery is greater than 45Wh / kg, and 80 percent of the DOD can be recycled by over 1400 times under normal temperature.

Description

technical field [0001] The invention relates to a lead-acid battery. Background technique [0002] As the national environmental protection requirements become more and more stringent, our demand for clean energy is also increasing. Tubular battery is a new type of green power battery. The positive plate adopts tubular plate, which can effectively prevent the active material from falling off. The power is more than 20% larger than that of conventional lead-acid batteries, and the life is generally about twice as long as that of conventional lead-acid batteries. The high temperature and low temperature characteristics are much better. However, the negative plate of the traditional tubular battery uses a paste plate, and its cycle life cannot match the cycle life of the positive plate of the tubular battery. At the same time, the negative plate has a poor ability to accept high-current charging. Contents of the invention [0003] The object of the present invention is to p...
