Abstract

The invention relates to an electrode plate solidification technology for lead-acid battery. The solidification technology comprises a moisture retention phase, a thermal insulation solidification phase, and a drying phase. In the moisture retention phase, a low-temperature solidification treatment is carried out at first, the temperature in the low-temperature solidification treatment is 40 to 45 DEG C, then a high-temperature solidification treatment is carried out, and the temperature in the high temperature solidification treatment is 75 to 85 DEG C. In the thermal insulation solidification phase, the relative humidity is gradually reduced during the solidification process. Electrode plates that are produced through the solidification technology are assembled into batteries. The floating charging resistant performance of the battery is prominently improved, and thus the service life of the battery is prolonged. The primary capacity of the battery is large, and the service life is 5 years or more. The electrode plate solidification technology is an ideal solidification mode for lead-acid battery for communication.

Description

technical field [0001] The invention relates to the field of accumulators, in particular to a curing process for polar plates suitable for lead-acid accumulators which improves the service life of the lead-acid accumulators. [0002] Background technique [0003] Lead-acid battery (Lead-acid battery) electrodes are mainly made of lead and its oxides, and the electrolyte is a battery of sulfuric acid solution. Since the French G.Plante invented the lead-acid battery in 1859, it has experienced nearly 150 years of development. Great progress has been made, whether it is in transportation, communication, electric power, military or in various economic fields of navigation and aviation, lead-acid batteries have played an indispensable and important role. In recent years, with the acceleration of urbanization and the expansion of city limits, the traffic flow has increased dramatically. Although automobiles and other means of transportation are developing rapidly, due to t...
