Abstract

The invention discloses a formula of a polar plate lead plaster with high energy storage capacity, long service life and low temperature resistance, relating to the technical field of lead plasters of storage batteries. The polar plate lead plaster comprises the following components in parts by weight: 90-110 parts of lead powder, 0.5-0.7 part of precipitated barium sulphate, 0.2-0.3 part of sodium lignosulfonate, 0.2 part of carbon black, 0.05 part of chemical staples, 10-11 parts of sulfuric acid and 9-11 parts of pure water and is characterized by comprising 0.2-0.3 part of rare earth and 0.5-1 part of potassium bromide. According to the formula, the rare earth and the potassium bromide are added, so that the processed lead plaster is high in activity, rapid in charging and capable of improving the energy storage capacity and low temperature resistance of a storage battery.

Description

Technical field: [0001] The invention relates to the technical field of lead paste for batteries, in particular to a formula of lead paste with high energy storage, long life and low temperature resistance. Background technique: [0002] Lead paste is the matrix of the active material of the plate. It is a paste-like substance with certain plasticity formed by mixing lead powder with a certain degree of oxidation and apparent density with water and sulfuric acid through mechanical stirring; the role of lead paste in lead-acid batteries It is mainly to provide and store the substances required for electrochemical reactions. In the prior art, the lead paste used on the positive electrode and the negative electrode has different formulations. One type of lead paste used on the negative electrode has a better energy storage effect, but sometimes the charging is slow and takes a long time to charge. , poor low temperature performance. Invention content: [0003] The technical...
