Problems solved by technology

During the process of loading and unloading or waiting for people, the vehicle generally chooses to turn off the engine and use the on-board lead-acid battery to supply power for entertainment equipment, air conditioners, etc., resulting in deep discharge of the battery. After the vehicle is started, it will recharge due to the condition of the battery Insufficient battery capacity, resulting in long-term battery loss and shortened service life

Abstract

The invention relates to the technical field of a lead-acid battery, particularly relates to a high recharge rate lead-acid battery negative lead paste, a battery negative plate and a high recharge rate lead-acid battery and has properties of good charge acceptance after deep discharge and long cycle life. The lead paste formula includes 100 parts of lead powder, 0.06-0.12 parts of short fiber, 0.5-1.5 parts of ultra-fine barium sulfate, 0.1-0.25 parts of carbon black, 0.05-0.12 parts of indulin, 8-12 parts of sulfuric acid and 9-13 parts of deionized water.

Description

technical field [0001] The invention belongs to the technical field of lead-acid batteries, and in particular relates to a lead-acid battery negative paste with a high recharge rate, a battery negative plate and a lead-acid battery with a high recharge rate. Background technique [0002] 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 demand of customers, businesses are increasingly installing entertainment equipment, air conditioners, electric blankets, etc. on vehicles in order to increase the selling points of vehicles. During the process of loading and unloading or waiting...
