Abstract

The invention discloses storage battery positive electrode lead paste, which is prepared from the following raw materials in parts by weight: 60 to 70 parts of lead powder, 15 to 28 parts of regenerated lead powder, 13 to 19 parts of deionized water, 7 to 12 parts of sulfuric acid solution, 1 to 2 parts of polyester staple fiber, 3 to 6 parts of pure graphene, 1 to 2 parts of stannous sulfate, 2 to 4 parts of polyaniline nanometer solution, 0.5 to 1 part of rare-earth elements, 0.3 to 0.7 part of humic acid, 1 to 2 parts of sodium sulfate, 2 to 4 parts of acetylene black and 1 to 3 parts of dispersing agents. The storage battery positive electrode lead paste can effectively solve the problem of fast attenuation of the circulation service life due to insufficient charging and low discharging volume of an existing lead storage battery for an electric bicycle under the low-temperature condition.

Description

technical field [0001] The invention belongs to the technical field of storage batteries, and particularly relates to a positive electrode lead paste of a storage battery and a preparation method thereof. Background technique [0002] At present, lead-acid batteries for electric vehicles are the core components of electric vehicles. It is a high-rate deep-cycle battery with reasonable design requirements and strict process control requirements. At present, this kind of battery has been produced for many years, and there is a problem that is constantly emerging, that is, the discharge capacity of the battery in winter is obviously low, and some can only reach 60% of the rated capacity, resulting in the driving mileage reaching the original. Half of consumers are very eager to drive the same mileage in winter as in spring and autumn. In winter, because the battery capacity decays quickly and the life is short, it is caused. SUMMARY OF THE INVENTION [0003] The invention ...
