Embodiment 1

[0013] Take a 10Ah battery for an electric bicycle as an example. After the acid filling is completed, the internalization is carried out. The specific internalization steps are as follows: 0.1A reverse charging for 20min, then forward charging, 0.8A charging for 4h, 1.8A charging for 12h, and 1.2A charging Charge for 38 hours, and charge for 6 hours at 0.6A.

Embodiment 2

[0015] Take the 10Ah battery for electric bicycle in Example 1, the specific internalization steps are as follows: 0.4A reverse charge 40min, then forward charge, 0.5A charge 2h, 0.8A charge 2h, 1.2A charge 64h, 1A charge 6h, 5A Charge for 2h, 0.6A charge for 24h.

Embodiment 3

[0017] Take the photovoltaic energy storage battery 100Ah battery as an example. After the glue is filled, the internalization is carried out. The specific internalization steps are as follows: 1A reverse charging for 30min, then forward charging, 8A charging for 4h, 18A charging for 12h, 12A charging for 38h , Turn to 6A and charge for 6h.

Abstract

The invention discloses a formation process of formation inverse charging in lead-acid batteries, which includes steps of acid filling or glue filing for the lead-acid battery. The formation process of formation inverse charging in lead-acid batteries is characterized in that after acid filling or glue filing and before charging, the battery is inverse-charged. The formation process of formation inverse charging in lead-acid batteries increases the battery formation efficiency in the lead-acid battery, and namely increases the content of PbO2 after polar plate formation, thereby resolving the hidden problems of long plate grid storage time, unstable combination process of lead paste, poor combination of the plate grid and lead paste and the like, namely increasing the conductivity between the plate grid and an active matter and further reducing the battery internal resistance.

Description

Technical field [0001] The invention belongs to the field of battery production, and specifically relates to a method for preparing a lead-acid battery. Background technique [0002] At present, the formation process of lead-acid batteries is roughly divided into external formation (plate formation) and internal formation (battery formation). The main difference between internal formation and external formation of batteries is: battery charging process. Assemble batteries with raw plates, and then charge with acid, which is called internalization into batteries; externalization into batteries means that during the construction of the battery, the batteries are put into the formation tank for charging and then the plates become cooked plates and then assembled The battery is then charged with acid. The battery obtained in this process is called externalized into a battery; externalized into a battery is currently a common charging process, in which no welding is to improve the con...
