Abstract

The invention discloses a high-performance power accumulator and a preparation method thereof. Graphite is substituted by a novel conductive agent, namely, polyaniline, in the lead paste of a positive plate; the conductivity of a mixture of the polyaniline and lead dioxide is improved by 12.5 times; acetylene black is substituted by a novel conductive agent, namely, super carbon black, in the lead paste of a negative plate, the specific surface area of the super carbon black is 130-190m<2> / g, and the adsorption is high. During preparation, water is firstly added, then an additive is added, the water and the additive are mixed and then lead powder is added, while the original steps of adding the additive firstly, adding the lead powder, adding the water and then stirring are changed, so that the additive is well dispersed. According to the high-performance power accumulator and the preparation method thereof, the utilization rate of an active material is effectively improved, the consistency of the battery is improved, the discharge depth of the battery is great, and the cycle life is long.

Description

technical field [0001] The invention relates to the technical field of storage batteries, in particular to a high-performance power storage battery and a preparation method thereof. Background technique [0002] At present, electric vehicles are an environmentally friendly means of transportation in my country. Lead-acid batteries for electric vehicles are the core components of electric vehicles. They are used in large quantities. They are high-rate recyclable batteries. The design requirements are reasonable and the process control requirements are strict. The performance of lead-acid battery products is mainly reflected in: 1. charge acceptance capacity; 2. low-temperature high-current discharge capacity; 3. active material utilization rate; 4. reaction area; 5. service life. [0003] For power batteries, the depth of discharge should be deep and the cycle life should be long. The formula and manufacturing method of the positive and negative plate lead paste largely deter...
