Container formation method of valve-regulated lead-acid battery

Abstract

The invention relates to a container formation method of a valve-regulated lead-acid battery, which is used for solving the problems of long time consumption and long production cycle of container formation of the valve-regulated lead-acid battery. The method is carried out according to the following steps: a. first charge: the charge time is 7.5h and the current is 1.7-1.9A; b. first discharge: the discharge time is 1h and the current is 1.36-1.52A; c. second charge: the charge time is 5h and the current is 1.7-1.9A; d. second discharge: the discharge time is 2h and the current is 1.36-1.52A;and e. third charge: the charge time is 6h and the current is 1.7-1.9A. The method provides the optimal mixing ratio of current strength to formation time, controls the water temperature during the process, fully forms a plate, forms the optimized container formation technology of the 12V7Ah valve-regulated lead-acid battery, shortens the formation time of the battery to one half of that of the prior art, saves energy consumption and simultaneously, greatly improves production efficiency.

Description

technical field [0001] The invention relates to a storage battery production process, in particular to a valve-regulated lead-acid battery internalization method, and belongs to the technical field of storage batteries. Background technique [0002] Lead-acid batteries have long service life, large capacity, good high-current discharge, high charge acceptance, excellent battery uniformity, small self-discharge, high reaction efficiency, and low raw materials, and have been used until now. While researching and developing new varieties, various manufacturers are constantly exploring ways to improve production efficiency. In the past, in order to shorten the formation time, various explorations have been made, such as increasing the temperature of the formation electrolyte, increasing the formation current or increasing the density of the electrolyte, etc., but the formation temperature is too high, resulting in insufficient initial capacity of the battery; increasing the form...
