Problems solved by technology

Lead-acid battery is a kind of equipment that continuously converts electrical energy and chemical energy. The number of conversions is directly related to the quality of the lead paste. This frequent start-stop working condition has a negative impact on the cycle life of the supporting battery.
However, the quality of the lead paste is affected by its preparation process, and the uneven mixing of the raw materials of the lead paste affects the quality of the lead paste, thereby reducing the service life of the battery

Abstract

The invention discloses a preparation process of lead plaster of a lead-acid storage battery, which comprises the steps of separately preparing positive electrode lead plaster and negative electrode lead plaster, and mixing raw materials by using a mixing and stirring device. The preparation process of the positive electrode lead paste comprises the steps of S11, selecting raw materials includingdilute sulfuric acid, deionized water, polyester staple fibers, lead powder and modified graphene of the positive electrode lead paste, respectively putting the polyester staple fibers, the lead powder and the modified graphene into a crusher to be crushed, sieving with a 200-400-mesh sieve, and weighing 8-12 parts by weight of dilute sulfuric acid, 7-10 parts by weight of deionized water, 0.1-0.15 part by weight of polyester staple fiber, 65-80 parts by weight of lead powder and 1-1.7 parts by weight of modified graphene for later use; The raw materials of the lead plaster are easy to obtain,and the lead plaster is prepared under conventional process conditions, so that implementation is easy.

Description

technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to a preparation process of lead paste for lead-acid batteries. Background technique [0002] Most of the power supplies for communication base stations and outdoor integrated cabinets are lead-acid batteries. Since the vast majority of communication base stations are built in the wild or in the suburbs of cities, these remote places or urban-rural fringe areas are limited by geographical conditions, and the city power supply is not normal enough, and there are occasional power outages. Lead-acid battery is a kind of equipment that continuously converts electrical energy and chemical energy. The number of conversions is directly related to the quality of lead paste. This frequent start and stop condition has a negative impact on the cycle life of the supporting battery. However, the quality of the lead paste is affected by its preparation process, and the uneven mixing ...
