Abstract

The name of the invention is positive electrode lead paste for a pregnant solution storage battery and a preparation method thereof, which belong to the technical field of lead-acid storage batteries,and mainly solve the problems of insufficient deep discharge cycle capability and short cycle life of the conventional pregnant solution starting type battery. The positive electrode lead paste is mainly characterized by comprising the following components in parts by weight: 70-90 parts of lead powder, 0.05-0.15 part of antimonous oxide, 0.05-0.12 part of high-strength glass fiber, 0.6-1.5 partof 4BS, 9-15 parts of red lead, 0.02-0.06 part of sodium perborate tetrahydrate, 4-8 parts of sulfuric acid and 6-12 parts of pure water. The method has the characteristics that the conductivity of the lead paste is enhanced, the deep cycle life of the battery is prolonged, and the process is simple and easy to control, and is mainly used for prolonging the cycle life of the pregnant solution storage battery and slowing down argillization failure of the positive lead paste in the use process of the pregnant solution storage battery.

Description

technical field [0001] The invention belongs to the technical field of lead-acid batteries. In particular, it relates to a positive-electrode lead paste for a liquid-rich storage battery and a preparation method thereof. Background technique [0002] With the development of the logistics industry, the use of commercial vehicles has been converted to home life, and the functional requirements for batteries are becoming stronger and stronger. The functions of conventional flooded start-up batteries can no longer meet the increasing functional requirements of customers, and need to meet more customer needs within a limited cost. [0003] The characteristics of customers' use are to use batteries to store electricity and continuously supply power to additional electrical equipment such as car refrigerators, air conditioners, and electric blankets. This requires conventional starting batteries to have strong deep discharge cycle capabilities. [0004] Through research and indus...
