Problems solved by technology

This is because the positive electrode active material, lead dioxide, has a strong oxidation ability, and it is difficult to find an oxidation-resistant and stable substance as an additive.
Secondly, the life of lead-acid batteries is often limited by the positive electrode, and the additive

Abstract

The invention discloses a formula of lead-acid storage battery positive pole diachylon. The lead-acid storage battery positive pole diachylon is prepared from the following components in percentage by weight: 70-90% of lead powder, 3-15% of sulfuric acid, 5-20% of water, 0.05-2% of short fiber, 1-20% of sodium perborate, and 0.1-10% of polytetrafluoroethylene emulsion; the sum of the weight percentage of all the components is 100%. According to the invention, by adopting the sodium perborate, the electric conductivity of active substance semi-conductors of the positive pole as well as binding force between the active substances and a grid are increased; by adding the polytetrafluoroethylene (PTFE) emulsion, the structure of the active substances during charging and discharging is ensured, softening and dropping of active substances are reduced, and thus the charging receptivity of the active substances of the positive pole is promoted and the cyclic service life of the battery is prolonged.

Description

technical field [0001] The invention belongs to the technical field of lead-acid storage batteries, and relates to a positive electrode paste formulation of a lead-acid storage battery, in particular to a positive electrode paste formulation of a paste-applied valve-controlled sealed lead-acid storage battery. Background technique [0002] From the currently recognized reaction mechanism of lead-acid batteries, it can be known that lead sulfate is converted into lead dioxide during the charging process of the positive electrode of the lead-acid battery, and lead dioxide is converted into lead sulfate during the discharge process. The structure of the porous electrode changes during the charging and discharging process. The reason is that the density and molar volume of the positive electrode active material lead dioxide and the product lead sulfate after discharge change. Theoretically, the volume change is as much as 2.6 times. The shrinkage and expansion of the volume duri...
