Problems solved by technology

The disadvantage is that although the internal formation process is beneficial to environmental protection, it is not energy-saving. Compared with the external formation, the formation charging capacity is increased by more than 50%, and the quality of the plate formation is not as good as that of the external formation.

Abstract

The invention provides a method for acid-free external formation of a lead-acid storage battery and the lead-acid storage battery. During the formation, a neutral electrolyte is used instead of a sulfuric acid electrolyte, which prevents acid mist pollution and avoids the contamination of the conventional external formation plate. Lead wastewater, while the conversion efficiency and plate quality are superior to the internal conversion process, and there is no waste acid generated in the internal conversion process, so as to achieve the purpose of saving energy and reducing emissions, and improving product quality.

Description

technical field [0001] The invention relates to a lead-acid storage battery, in particular to a method for the acid-free externalization of a lead-acid storage battery with energy saving, emission reduction, environmental protection and product quality improvement and the lead-acid storage battery. Background technique [0002] The state's policies on environmental protection and labor protection are continuously introduced (for example: "Lead-acid battery industry access conditions" stipulate that battery companies that started to build factories in 2013 need to adopt internal chemical synthesis technology), which means that the production process of lead-acid battery manufacturers The formulation should meet the requirements of environmental friendliness. In the existing battery production process, no matter whether the internal formation or external formation process is adopted, there is a problem of exposure formation. The achievement of battery exposure means that a lar...
