Abstract

The invention discloses a lead-carbon battery anode lead paste for a hybrid vehicle. The lead paste is obtained through mixing the following raw materials, by weight, 100 parts of lead powder, 4-15 parts of sulfuric acid, 0.05-5 parts of fumed silica, 0.05-3 parts of a rare earth oxide, 0.1-10 parts of red lead, 0.1-10 parts of Hydrargyri Oxydum Rubrum, 0.1-4 parts of graphite, 0.1-2 parts of a short fiber, and 10-20 parts of water. According to the invention, the fumed silica and the rare earth oxide are added to the lead paste, and other anode additives are also added to prepare the novel lead paste, a pole plate can be coated under a routine lead-acid battery production coating facility condition, the anode is obtained after curing, and there is very good adhesion between an active substances and a plate grid, and one active substance and another active substance, so the electrical properties of the battery are excellent.

Description

Technical field [0001] The invention involves the field of battery production and specially involves a mixed -power car charcoal battery cream and its preparation method. Background technique [0002] Because the hybrid vehicle battery is in some load -long state, shallow charge, high charging and discharge frequency, and large current, it is easy to cause negative vulcanosulfate, which will fail the battery.Patent CN101969149A proposes that adhesives and carbon materials are added to the conventional battery formula's negative lead cream formula, which will significantly delay the negative electrode sulfate.Studies have found that after the above materials are added to the negative lead paste, the negative vulcanosulfate is suppressed, the battery's large current charging discharge performance is improved, and the cycle life of the hybrid vehicle operation mode is significantly prolonged.However, with the extension of the loop life of the negative plate, the battery will soften ...
