Problems solved by technology

[0002] Lead-acid battery is a kind of traditional product. It is widely used in the fields of standby power supply, energy storage and power supply by virtue of its excellent performance-price ratio. In the discharged state, the main component of the positive electrode is lead dioxide, and the main component of the negative electrode is lead; The main component of the positive and negative electrodes in the charging state is lead sulfate. In recent years, with the rapid development of the automobile industry, telecommunications and IT networks and other infrastructure, power vehicles and renewable energy industries, it is the preferred lead-acid battery and its battery industry. With rapid development, safe, efficient and energy-saving lead-acid batteries have received more and more attention. However, the existing lead-acid batteries on the market generally have defects such as poor cost performance and short service life, which can no longer meet the existing market demand.

Abstract

The invention discloses a power lead storage battery. The power lead storage battery comprises a positive plate and a negative plate, wherein the positive plate comprises a positive grid and positivelead plaster, and the negative plate comprises a negative grid and negative lead plaster. The power lead storage battery disclosed by the invention has the advantages that carbon nanotubes are used toreplace activated carbon and acetylene black adopted in the traditional art, so that the current density and the electrode polarization during discharging are effectively reduced, a smaller internalresistance of the battery is achieved, the lead plaster porosity is increased, and the lead plaster utilization efficiency and the charge acceptance are improved; and titanium nitride, which has a high melting point, high intensity, high hardness, high acid and alkali corrosion resistances, high wear resistance, high pyrochemical stability and excellent electricity-conducting and heat-conducting performances, is added to prevent the forming of a passivation layer between each grid and the corresponding lead plaster, so that early capacity fading of the storage battery can be avoided, and the overall service life of the storage battery can be prolonged.
