Abstract

The invention relates to a container formation technology of a valve-closed charging type valve controlled sealed lead-acid battery. The technology comprises the following steps: adding acid into a valve controlled sealed battery, cooling off the battery in a water bath, allowing the battery to stand still for 2 to 4 hours, then covering the safety valve, binding the battery cover, and connecting the battery to a charging machine, wherein the battery container formation technology is divided into three phases. During the battery container formation process of the lead-acid battery container formation technology, acid is quantitatively added, so no acid is left after the container formation process, and thus the process of extracting acid from the lead-acid battery is saved. During the battery container formation process, a one-way valve is adopted to control the discharging of acid smog, and the acid extracting process after the battery container formation is also saved, so the environmental influence of the acid smog and processing of the extracted excess acid is reduced. The container formation technology simplifies the operation, reduces the production cost, does not generate wastewater due to electrode plate formation, reduces the environmental pollution, and improves the production efficiency.

Description

technical field [0001] The invention relates to the field of storage batteries, in particular to an internal formation process for lead-acid storage batteries that improves production efficiency and is environmentally friendly. [0002] Background technique [0003] 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 large amount of acid mist is generated, which affects the environ...
