Five-charge three-discharge storage battery container formation method

Abstract

The invention relates to a five-charge three-discharge storage battery container formation method. The method is characterized by adopting a five charging steps and three discharging steps to complete the container formation and comprising the following steps of first-time charging: charging the storage battery for 3min through the current of 1.8A, and standing for 2h; second-time charging: charging the storage battery for 3h through the current of 1.8A, then charging the storage battery for 14h through the current of 2.4A, and charging the storage battery for 5h through the current of 1.2A; first-time discharging: discharging the storage battery for 2h through the current of 3A; third-time charging: charging the storage battery for 12h through the current of 2.4A, and then charging the storage battery for 5h respectively through the currents of 1.8A and 1.2A; second-time discharging: discharging the storage battery for 2h through the current of 3A; fourth-time charging: charging the storage battery for 10h through the current of 2.4A, then charging the storage battery for 5h respectively through the currents of 1.8A and 1.2A, and standing for 2h; third-time discharging: discharging the storage battery to 10.5V through the current of 6A; and fifth-time charging: charging the storage battery for 4h through the current of 2.4A, charging the storage battery for 5h through the current of 1.8A, charging the storage battery for 5h through the current of 1.2A, charging the storage battery for 3h through the current of 0.1A, and finally extracting the acid. The method is simple in process, a great amount of working hours and energy can be saved, and the economic benefit of enterprises can be improved.

Description

technical field [0001] The invention belongs to the technical field of accumulator manufacturing, and in particular relates to a process of internal formation, especially a method for internal formation of accumulators using a method. Background technique [0002] The formation power of the battery is one of the main factors affecting the formation of the battery. The formation power is too low, the active material is not fully converted, and the content of lead dioxide is low, which leads to poor initial performance of the battery, and the high formation power increases the energy loss. In addition, the temperature rise in the formation process is not easy to control, and the impact of the gas on the plate is also large, which will affect the battery life. Therefore, the formation process of the battery is very important. For the formation of small and dense batteries, the previous technology used three The process of charging and discharging for formation often takes u...
