Abstract

The patent of the present invention relates to a method for manufacturing a lead-carbon battery for a micro-hybrid electric vehicle, which is characterized in that it includes the following steps: step 1), the polyurethane sponge is degreased, roughened, neutralized, pre-soaked, activated, Electroless silver plating is finally electroplated with lead to obtain foamed lead material; step 2), cutting the above-mentioned foamed lead material into shape, coating the negative electrode active material, adding carbon black as an additive to the active material; step 3), the negative plate is cured, After drying, it is assembled with the positive plate made by ordinary gravity casting method to form a finished battery. The method of the invention can greatly improve the performance of the lead-acid battery.

Description

Technical field [0001] The patent of the invention relates to a manufacturing method of a lead-carbon battery for a micro-hybrid vehicle. technical background [0002] The Ministry of Industry and Information of China pointed out in the "Energy-saving and New Energy Vehicle Industry Development Plan (Draft)" that by 2015, micro-hybrid vehicles should be industrialized. The micro-hybrid system with automatic start-stop function has become the standard configuration of passenger cars. A micro-hybrid vehicle is a new type of energy-saving and environmentally-friendly vehicle product that automatically turns off the engine when the vehicle is stopped intermittently and reduces the fuel consumption and emissions of the engine at idle speed. It is equipped with a belt-driven starter-generator integrated motor on the traditional engine. When the car is started, the battery provides energy to start the car. [0003] The price of traditional lead-acid batteries is lower than that of lithi...
