Description

A kind of internal formation process of lead-acid battery
Technical field
The present invention relates to battery technology field more particularly to a kind of internal formation process of lead-acid battery.
Background technique
Environmental protection and labor protection policy constantly put into effect (such as: " lead-acid accumulator industry access condition " Middle regulation, internal formation process need to be used by starting within 2013 the battery manufacturers founded the factory), it is meant that lead-acid storage battery production enterprise is raw The formulation of production. art should meet environmental-friendly requirement.No matter using being internalized into or alienation during existing storage battery production At technique, the problem of chemical conversion there is opening, the chemical conversion of battery opening has meant that a large amount of acid mist generates, and influences environment.
In the manufacturing process of battery, need to swash positive and negative anodes substance inside pole plate by certain charge and discharge system It is living, it is changed into state-of-charge, improves this chemical reaction process of the comprehensive performances such as charge-discharge performance and self discharge, storage of battery Referred to as chemical synthesis technology process, container formation are that after the assembly is completed, dilute sulfuric acid, chargingization is added in green plate assembled batteries At making the conversion positive/negative plate substance of green plate.Be internalized into lead-acid accumulator all and be by the way of quantitative rich solution into Row Battery formation proposes extra free acid in the latter stage of battery charging, to prevent battery from leaking the generation of sour phenomenon.By Be in lead-acid battery used under lean solution state, once free acid excess, will result in the sour phenomenon of leakage.
Electric bicycle in recent years and it is very universal, main power source is lead-acid accumulator, lead-acid accumulator There are mainly two types of formation regime: one is battery tank formation, plates polarizing being carried out supplement electricity at being assembled into after battery, another kind is Then container formation, green plate direct-assembling are being melted at finished battery；And acid of the tank formation than being internalized into discharge Liquid, sewage and dust are relatively more, seriously pollute environment, so lead-acid accumulator is mostly using being internalized at present, however mesh Preceding existing lead-acid accumulator is internalized into that the time is especially long, charge volume is big, not only causes very big energy waste, but also pole plate Formation effect is bad, and battery with two side terminals is poor
Summary of the invention
Technical problems based on background technology, the invention proposes a kind of internal formation process of lead-acid battery.
A kind of internal formation process of lead-acid battery proposed by the present invention, comprising the following steps:
