Problems solved by technology

[0006] (3) Irreversible sulfation: When the battery is over-discharged, stored for a long time after discharge or stored in a discharged state, the plate will generate a coarse lead sulfate that is difficult to accept charging under the action of dissolution and recrystallization of lead sulfate Crystallization, this phenomenon is called irreversible sulfation, which will lead to electrode failure and failure to charge in severe cases
If the alloy of the busbar electrode is impro

Embodiment Construction

[0014] The present invention is further described in detail through preferred embodiments below.

[0015] In the container, prepare the components together by conventional production methods in the following table 1 to form a lead paste, the apparent density of the lead paste is 4.34±0.05g / cm 3 . The lead paste is very beneficial for filling and coating some thin polar plates, and just meets the requirements of the polar plates of motorcycle batteries.

Abstract

The invention discloses a battery and a cathode composition thereof. The composition comprises the following components in percentage by weight: 80.8-82.6 percent of lead powder, 0.13-0.17 percent of carbon black, 0.06-0.1 percent of sodium lignosulfonate, 0.39-0.43 percent of humic acid, 0.1-0.13 percent of oxygen resistant agent, 0.32-0.5 percent of barium sulfate, 0.03-0.05 percent of short fiber, 7.1-8.0 percent of sulfuric acid and 8.9-9.9 percent of pure water. In the invention, the battery has high over-charge and over-discharge resistance and prolonged service life, and reserves simultaneously the advantages of high capacity, good large-current discharge performance, good low-temperature characteristic, and the like.

Description

technical field [0001] The invention relates to the technical field of mobile power supply, in particular to a battery and a negative electrode composition thereof. Background technique [0002] Motorcycles, automobiles, and ship engines are mainly powered by lead-acid batteries. At the same time, lead-acid batteries can also be used as power sources for lighting, horns and other facilities. Due to the uneven quality of vehicles and their wide range of uses, especially for passenger vehicles, batteries are required to have higher resistance to overcharge and overdischarge. However, the existing lead-acid battery products are only implemented according to national standards, and cannot meet the higher performance requirements of overcharge and overdischarge resistance. The actual service life often fails to meet the expected one-year requirement, and can only maintain 6 8 months. [0003] The premature termination of battery life is generally considered to have the followin...
