Lead-acid battery nano carbon activating agent

Abstract

This invention is a carbon active agent for the lead acid battery. The size of the particles of the carbon powder is less than 15 m. The active agent has an excellent electro-conductive property. The carbon active agent is poured into the lead battery for use, and the particles of the carbon powders are absorbed onto and osmosed into the positive electrode plate by means of the electricity to form a conductive membrane with a huge surface area and new base cores. It makes the battery (1) be charged in a large current and discharged in the current as double times or more as the nominal current with the temperature of the battery being within a standard range, (2) have decreased internal resistance, (3) prolong its using life by double times or more, (4) revive a battery if it was wasted.

Description

Technical field: [0001] The invention relates to the field of lead batteries, in particular to improving the comprehensive performance of lead-acid batteries, regenerating discarded lead-acid batteries, and reusing discarded sulfuric acid electrolytes. Pollution from waste lead batteries is reduced. That is, it protects the environment, prolongs the service life of the lead battery and saves energy, a lead-acid battery activator with carbon powder particles of <15nm. Background technique [0002] Recently, the traditional use of lead-acid batteries in my country mainly has performance problems and environmental pollution problems caused by waste batteries. In terms of battery performance, since the invention of lead-acid batteries, PbO 2 As the positive electrode, the lead is used as the negative electrode, and the basic principle of oxidation and reduction has been continued with dilute sulfuric acid electrolyte. Today's lead batteries are also based on this principle...

AI Technical Summary

Problems solved by technology

[0003] The current lead-acid batteries have the problems of corrosion of the electrode plate and the decline of the corrosion resistance and conductivity of the electrode active material, which makes the lead battery as a performance limitation in a certain sense between its superior performance and its appearance.

Cathode PbO 2 It is a kind of semiconductor material, and its electrical conductivity is extremely sensitive to temperature, especially doping. Due to the continuous doping of non-conductive lead sulfate on the positive plate during the charge and discharge process, the conductivity of the positive plate decreases sharply. It may even cause the battery to fail to be charged, leading to the scrapping of the battery or partial thermal expansion and contraction of the battery during discharge, resulting in cracking, erosion, and shedding of the positive plate, resulting in loss of function

[0004] Secondly, regarding environmental issues, traditional lead-acid batteries are scrapped after 2-3 years of use.

Due to the high cost of processing, recycling, and recycling waste materials, practitioners engaged in waste disposal have no way to deal with them, and actually pile them up and discard them in the wild
