Problems solved by technology

However, from the point of view of the battery cycle life produced by the two processes, the life of the battery produced by the battery formation (internal formation) process is not as good as that of the battery produced by the groove formation (external formation) production process.
[0003] In order to solve the problem of short battery life produced by the battery formation process, it is necessary to improve the existing battery formation process to increase the battery cycle life

Abstract

The invention discloses an acid-adding charging method for prolonging the cycle life of a power valve-regulated lead-acid storage battery. The method comprises the following steps: 1, putting the valve-regulated lead-acid storage battery provided with a green plate into a vacuum acid-adding machine, and adding a low-acid-density electrolyte of which the acid amount is 50-67% of the acid amount required by the battery into the battery through the vacuum acid adding machine, and then vacuumizing to make the vacuum degree reach -0.085 MPa; 2, electrically connecting the two ends of the unformed plate of the battery with a power supply, charging for 10-20 hours, and then pausing charging; and 3, adding the high-acid-density electrolyte with the residual acid amount required by the battery into the battery on line through the vacuum acid adding machine. The technical problem that the service life of the battery produced by the battery formation process is short is solved, and the cycle life of the power valve-regulated lead-acid storage battery is prolonged.

Description

Technical field: [0001] The invention relates to the technical field of valve-regulated lead-acid battery production, in particular to an acid charging method for improving the cycle life of a power-use valve-regulated lead-acid battery. Background technique: [0002] With the strengthening of people's awareness of environmental protection, enterprises pay more and more attention to the protection of the environment in the production process. At present, the production of lead-acid batteries has basically adopted the battery formation (or internal formation) process instead of the tank formation ( That is, external chemical synthesis) production process. However, from the point of view of the battery cycle life produced by the two processes, the battery life of the battery formation (internal formation) process is not as good as that of the battery formation (external formation) production process. [0003] In order to solve the problem of short battery life produced by the...
