Problems solved by technology

[0004] On the basis of studying the respective characteristics of the above two kinds of storage batteries, the present invention aims to solve the problem of large capacity and short service life of plate storage batteries, and small capacity and long service life of tubular storage batteries, and comprehensively utilizes the strengths of the two storage batteries. The thickness of the grid has been improved, and the composition of the battery alloy and the composition of the active material have been improved at the same time to produce a long-life plate-plate lead-acid battery
Alloys have their own advantages, but they still need to be improved in terms of corrosion resistance, high strength, and uniform distribution of elements.

Abstract

The invention discloses a power lead-acid storage battery, which comprises a positive grid alloy, a negative grid alloy, a positive active material and a negative active material. Metal Na and metal Sn are added to the grid alloy of the lead-acid storage battery for power in the invention, which effectively improves the binding ability of the grid and the active material, prolongs the service life of the battery, and does not greatly change the corrosion resistance at the same time.

Description

technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to a power lead-acid battery and a manufacturing method thereof. Background technique [0002] The production process of plate-type lead-acid batteries is relatively simple: because the plate coating machine is used for fast coating, less pollution, and easy processing, and the plates can be made very thin, so that the instantaneous discharge of the battery is large. Therefore, plate-type lead-acid batteries are the first choice for automobile starting batteries, and are also the most widely used battery production method in the production of spare valve-regulated batteries. [0003] However, in the production of electric vehicles, due to the special requirements of electric vehicles on the power supply, such as: long-term rate, long life, and large capacity, currently all manufacturers basically use tubular plate lead-acid batteries. The feature of the tubular plate le...
