Abstract

The invention relates to a manufacturing method of a lead-carbon battery used for a pure electric vehicle. The manufacturing method of the lead-carbon battery is characterized in that the manufacturing method comprises the following steps: step 1) orderly removing oil of polyurethane sponge, coarsening, neutralizing, presoaking, activating, and chemically silvering the polyurethane sponge, and finally carrying out electrification and lead plating on the polyurethane sponge to obtain foamed lead material; step 2) cutting and shaping the foamed lead material, respectively coating positive and negative active materials, and adding carbon black into the negative active material to be used as an additive; and step 3), solidifying and drying positive and negative electrode plates, and then assembling the positive and negative electrode plates into a finished battery. The manufacturing method can obviously enhance the performance of the battery.

Description

technical field [0001] The invention relates to a method for manufacturing a lead-carbon battery for pure electric vehicles. technical background [0002] The development of pure electric vehicles has a long history, and it has been more than 100 years. A pure electric vehicle is a vehicle that uses a single battery as an energy storage power source. It uses the battery as a power source for energy storage, and provides electric energy to the motor through the battery to drive the motor to run, thereby propelling the car forward. However, this energy-saving and environment-friendly automobile product can only be used in certain specific ranges and occasions at present, mainly because the defects of the power supply system restrict the development of pure electric vehicles. The power sources used in pure electric vehicles, such as lead-acid batteries, lithium-ion batteries, nickel-cadmium batteries, and nickel-metal hydride batteries, are generally expensive, short in servi...
