Embodiment Construction

[0007] When preparing the electrolyte, the additives in the electrolyte should be prepared first, and the powders of sodium lignosulfonate, humic acid, tetrabutylammonium bromide, polyoxyethylene sorbitan monolaurate, and CoSO4 in the additives should be calculated. Mix the weighed various powders evenly, add a small amount of deionized water to wet the slurry, then add an appropriate amount of deionized water as a solvent, and stir the mixed solution for 10 minutes with a high-speed dispersing device. At this time, you can The uniformly stirred mixed solution is used as an additive of the electrolyte.

[0008] Slowly add the prepared additive to the weighed sulfuric acid, mix and stir evenly, and finally use deionized water to fine-tune the mixed solution to 100% by weight to obtain the required battery electrolyte.

Abstract

An electrolyte formula of waterless internalized formation battery and a preparation method thereof are disclosed, and relate to the field of storage battery. At present, formation of the battery production process often adopts the water bath temperature reduction internalized formation method at present in domestic, but the method wastes and pollutes water resources and affects the shell appearance aberration of the battery outer shell. The electrolyte formula of waterless internalized formation battery is characterized by comprising following components in percentage by weight: 0.2 to 0.75 wt% of sodium lignosulfonate, 0.25 to 0.75% wt% of humic acid, 1.5 to 2 wt% of tetrabutylammonium bromide, 1.5 to 2 wt% of polyoxyethylene sorbitan monolaurate, 0.05 to 0.25 wt% of CuSO4, 90 to 95 wt% of sulfuric acid, and the rest is deionized water. The method has the advantages of no need of water bath temperature control, energy conservation and environmental-friendliness.

Description

technical field [0001] The invention relates to a storage battery, in particular to an electrolyte formula for an anhydrous internalized storage battery and a preparation method thereof. Background technique [0002] At present, the formation method in the domestic battery production process generally adopts a water bath to cool down and internally form, that is, to adjust the reaction temperature inside the shell when the battery is internally formed by circulating water, but this method not only wastes and pollutes water resources, but also damages the shell of the battery shell. The color difference in the appearance of the body has an impact. Contents of the invention [0003] The object of the present invention is to provide an electrolyte formula for an anhydrous internalized storage battery and a preparation method thereof, which can overcome the problems of water waste, pollution and color change of the shell, and has the characteristics of no need for water bath t...
