Abstract

The invention discloses a positive pole and paste of a long-service-life power lead-acid storage battery. Raw materials of the positive pole and the paste of the long-service-life power lead-acid storage battery consist of, by weight, lead powder 80-85%, sulfuric acid 6-9%, stannous mono-sulphate 0.1-0.2%, conductive fiber 0.05-0.07%, colloidal graphite 0.2-0.3%, cerium oxide 0.05-0.09%, 4BS seed crystal 0.8-1.0% and the balance deionized water. By adopting the positive pole and paste of the long-service-life power lead-acid storage battery, the matching relationship of the existing battery capacity and the service life can be effectively solved, the battery capacity is improved, and the service life is prolonged. In addition, the consistency of a pole plate is improved remarkably, and accordingly the problems including uneven formation and the like are effectively solved.

Description

technical field [0001] The invention relates to the technical field of lead-acid batteries, in particular to a positive electrode and paste of long-life power lead-acid batteries. Background technique [0002] Ordinary batteries are also called lead-acid batteries. Its electrodes are composed of lead and lead oxides, and the electrolyte is an aqueous solution of sulfuric acid. The main advantages are stable voltage and low price; the disadvantages are low specific energy (that is, the electric energy stored per kilogram of battery), short service life and frequent daily maintenance. Old-fashioned ordinary batteries generally have a lifespan of about 2 years, and it is necessary to regularly check the height of the electrolyte and add distilled water. However, with the development of technology, the life of ordinary batteries has become longer and easier to maintain. [0003] Lead-acid batteries have been widely used in various low-speed vehicle markets, and a lot of resear...
