Abstract

The invention relates to a lead-acid battery negative electrode additive, in particular to a lead-acid battery negative electrode composite additive and its preparation and use method, which is prepared from the following raw materials in terms of mass percentage: 5% to 15% of rubber bowl extract, wood Sodium Sulfonate 4-8%, Humic Acid 5-15%, Carbon Black 5-10%, Barium Sulfate 20-30%, and Tetrabasic Lead Sulfate 30-40%. Mix all components into a ball mill during preparation Medium grinding for 2 to 4 hours, and put into use according to 2 to 3% of the weight of lead powder when used. The advantages of the invention are: (1) the tetrabasic lead sulfate is used as the negative electrode paste additive, thereby comprehensively improving the performance of the negative electrode lead paste of the lead-acid battery, improving the charging acceptance capacity and low-temperature discharge performance of the battery, and prolonging the service life; (2) Various additives are optimized and compounded to form a "one package" composite additive, which is easy to use and avoids production operation errors.

Description

technical field

[0001] The invention relates to a lead-acid battery negative electrode additive, in particular to a lead-acid battery negative electrode composite additive and its preparation and use methods. Background technique

[0002] Additives are an important component of lead-acid batteries and have an important impact on the performance of batteries. Additives added to lead-acid batteries are generally divided into: plate additives and electrolyte additives. Plate additives are added when mixing the paste. For the negative plate, the main function is to resist shrinkage, also known as expansion agent; for the positive plate, it mainly increases the strength of the plate, prevents softening, falling off, and increases conductivity. The electrolyte additive is added when the electrolyte is prepared, and its main function is to increase the charge and discharge performance of the battery and slow down grid corrosion.
