Problems solved by technology

In recent years, with the rapid development of transportation, air transportation and some other industries, the demand for forklifts is also increasing. However, the existing forklifts are powered by diesel engines. Diesel engines are noisy and when diesel combustion is insufficient Heavy smog pollutes the environment and air. Using batteries as the power source of forklifts has neither noise nor smog. However, the existing maintenance-free lead-acid batteries have a maximum operating current of only a few hundred amperes, which cannot meet the needs of forklifts when they are frequently started. Thousands of Amperes Current Requirements

Abstract

Main characteristics are that changing materials of positive and negative pole plates increases working current; changing structure of positive pole plate as well as material and structure of diaphragm makes accumulator stand in rich liquid state. Thus, electrolyte can flow inside accumulator so that time of formation procedure in producing accumulator is shortened, production efficiency is raised, and production cost is reduced as well as operation requirement of large current is satisfied. Advantages are: large capacity, and power, long service life, no noise and air pollution, and satisfying power requirement of fork lift truck.

Description

technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to a battery for forklifts. Background technique [0002] The application fields of batteries are very wide. Some batteries are used as auxiliary power supply, and some batteries are used as backup power supply. The existing lead-acid batteries, no matter what their use is, their main structure basically consists of the following parts. According to the voltage The current requirements are different, and it is composed of several monomers connected in series and parallel. Each monomer is composed of a shell, positive and negative plates in the shell, a diaphragm between the positive and negative plates, and the electrolyte in the shell. As a maintenance-free For lead-acid batteries, the diaphragm is made of ultra-fine glass wool. After the electrolyte is injected into the shell, it is fully absorbed by the diaphragm made of ultra-fine glass wool, and the electrolyte will...
