Abstract

The invention provides a mild condition lead-acid battery additive and a preparation method and application thereof, and relates to the technical field of lead-acid batteries. The additive for lead-acid batteries with mild conditions comprises, by weight, 8-12 parts of chitooligosaccharide stearic acid, 12-36 parts of protamine sulfate, 1-3 parts of nitric acid, 1-3 parts of sodium silicate, 2-6 parts of acetylene black, 0.2 to 0.6 part of polyvinylpyrrolidone, 0.3-0.6 part of decylethylamine hydrochloride, 0.5-1.5 parts of zwitterionic surfactant and 100-120 parts of water. The additive has reasonable formula, small amount of use and wide application range, can effectively alleviate the polarization phenomenon of an electrode, enhance the charge acceptance ability of the battery, and improve the cycling times of the battery. The service life of the lead-acid battery can be prolonged, the preparation and use of additives are simple, and the conditions of use are mild.

Description

Technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to an additive for lead-acid batteries with mild conditions, and a preparation method and application thereof. Background technique [0002] Lead-acid batteries are widely used in electric power, transportation and other fields because of their good reversibility, voltage stability, and rich sources of raw materials. They are indispensable products in social production and business activities and human life. Lead-acid batteries currently in use are mainly divided into two types: non-closed lead-acid batteries and enclosed lead-acid batteries. Due to the difficulty and cost of production of non-closed lead-acid batteries, they are less expensive than enclosed lead-acid batteries. Non-closed lead-acid batteries are the main ones, but the current non-closed lead-acid batteries have a short service life, and the phenomenon of electrode vulcanization often occurs. The lead sulfate...
