Abstract

The invention relates to the field of battery preparation and discloses a high-efficiency container formation method for a 20Ah lead-acid storage battery. The method comprises the following steps of (1) adding acid to a 20Ah lead-acid storage battery and then standing for 1-1.5h; (2) charging at current of 1A for 1-2h; (3) charging at the current of 2A for 1.5-2h; (4) charging at the current of 3Afor 3-3.5h; (5) charging at the current of 5A for 7-7.5h; (6) charging at the current of 2.5A for 6-6.5h; (7) charging at the current of 3A for 1-2h; (8) charging at the current of 3.7A for 2h; and (9) charging and / or discharging at the current of 0-10A for multiple times separately, wherein each charging and / or discharging time is 0.25-4h. According to the high-efficiency container formation method, the charging / discharging time, sequence and current magnitude at an early stage of container formation of the battery are adjusted, and the formation time is controlled within 2d, so that the formation effect is good and the cost is low.

Description

technical field [0001] The invention relates to the field of battery preparation, in particular to a high-efficiency internalization method for a 20Ah lead-acid battery. Background technique [0002] Electric bicycles have become very popular in recent years, and their main power source is lead-acid batteries. There are two main formation methods of lead-acid batteries: one is the external formation of batteries, and the polar plates are formed and assembled into batteries to supplement electricity, and the other is For the internal formation of batteries, the raw plates are directly assembled into finished batteries, and then formed; while the external formation discharges more acid, sewage and dust than the internal formation, seriously polluting the environment, so the internal formation process has certain advantages. [0003] The Chinese patent application number 201410541611.7 discloses a multi-stage charge-discharge internal formation process for lead-acid batteries. ...
