Problems solved by technology

If these entertainment devices are used improperly, the life of the battery will be shortened. When the vehicle is loading and unloading or waiting for people, it will generally choose to turn off the engine, and use the on-board lead-acid battery to power the entertainment device, air conditioner, etc., resulting in deep discharge of the battery. , after the vehicle is started, there is a phenomenon that the recharge capacity is insufficient due to the limitation of the battery itself, and then the battery loses power for a long time, and the service life is shortened

Abstract

The invention relates to a storage battery with recharging performance under the condition of power shortage and green plate lead plaster. The storage battery green plate lead plaster is composed of positive plate lead plaster and negative plate lead plaster, and the positive plate lead plaster is prepared from the following raw materials in parts by weight: 80-90 parts of lead powder, 2-5 parts of titanium black, 1-2 parts of calcium hydrophosphate, 2-4 parts of modified carbon nanotubes, 0.5-1 part of hydrofluoric acid, 0.5-1 part of fumed silica, 5-8 parts of ultrapure water and 6-9 parts of sulfuric acid. The negative plate lead plaster is prepared from the following raw materials in parts by weight: 75-82 parts of lead powder, 0.2-0.6 part of superfine barium sulfate, 1.5-2.5 parts ofxylene, 6-10 parts of acetylene black, 4-6 parts of fullerene, 3-5 parts of modified carbon nanotubes, 5-7 parts of ultrapure water and 6-9 parts of sulfuric acid. The storage battery with the recharging performance under the condition of power shortage, which is prepared from the lead plaster of the green plate, has the advantages of higher recharging rate, namely good charging acceptance afterdischarging and long deep cycle life.

Description

technical field [0001] The invention belongs to the field of accumulators, and in particular relates to an accumulator with recharging performance under power loss and a lead paste for a raw electrode plate. Background technique [0002] The storage battery was invented by Plante in 1859 and has a history of more than 100 years. Lead-acid batteries have become one of the battery varieties with the largest output and widest uses in the world since they were invented, especially lead-acid Applications of batteries in the automotive industry. During the starting process of the car, the lead-acid battery is discharged, the battery is in a state of floating charge, and the discharge depth is shallow, and the battery is a shallow cycle battery. [0003] Now, with the increasing demands of customers, automakers are increasingly installing entertainment equipment, air conditioners, electric blankets, etc. on vehicles in order to make cars more attractive. If these entertainment d...
