Problems solved by technology

[0003] The present invention mainly provides a valve-controlled sealed lead-acid battery production process that can improve the hydrogen evolution overpotential of the negative plate, reduce water loss, and prolong the service life of the battery. The antimony in the grid will be transferred to the surface of the negative grid, resulting in a decrease in the hydrogen evolution overpotential, leading to technical problems such as a decrease in battery performance

Embodiment 1

[0016] A kind of valve-controlled sealed lead-acid storage battery production technology of the present invention, comprises following sequential steps:

[0017] 1) Insert the unformed positive electrode plate into the formation tank, and use a pure lead plate of the same area as the corresponding negative electrode (the pure lead plate can be used permanently), perform external chemical conversion treatment on the positive plate, and wash the formed positive plate with water dry.

[0018] 2) Insert the unformed negative electrode plate into the formation tank, and use a pure lead plate of the same area as the corresponding positive electrode (the pure lead plate can be used permanently), and perform external chemical formation treatment on the negative plate.

[0019] 3) Carry out protective discharge treatment on the formed negative electrode plate (or not perform protective discharge treatment), and carry out water washing and anti-oxidation treatment after the negative ele...

Abstract

The invention discloses a valve-controlled sealed lead-acid battery, and provides a new valve-controlled sealed lead-acid battery production process that can increase the hydrogen evolution overpotential of the negative plate, reduce water loss, and prolong the service life of the battery. During the charging process of the existing plates, the antimony in the positive plate grid will be transferred to the surface of the negative plate grid, resulting in a decrease in the hydrogen evolution overpotential and a decrease in battery performance. A good positive plate and an unformed negative plate are assembled into a battery, and then internalized into a negative plate.

Description

technical field [0001] The invention relates to a valve-controlled sealed lead-acid battery, in particular to a valve-controlled sealed lead-acid battery production process capable of increasing the hydrogen evolution overpotential of the negative plate, reducing water loss and prolonging the service life of the battery. Background technique [0002] Lead-acid battery is a traditional chemical energy storage device, which occupies an important position in the national economy. According to the statistics of the International Lead Association in 2015, the total amount of secondary chemical power sources in the world in 2014 was 68 billion US dollars, of which lead-acid batteries accounted for 68%. It has the advantages of low price and easy recycling, so it is widely used. Lead-acid batteries are divided into two types: flooded lead-acid batteries and valve-controlled sealed lead-acid batteries. Traditional flooded lead-acid batteries mainly use high-antimony and medium-antim...
