Problems solved by technology

However, in its preparation, the capacitive electrode material must be made into particles, which not only complicates the preparation process, but also may result in inability to mix uniformly.
At the same time, the hydrogen evolution inhibitor is not added to the lead paste, and the added carbon cannot exert the characteristics of the supercapacitor, that is, it cannot guarantee that the supercapacitor will be charged and discharged first during the charging and discharging process, which will protect the battery.

Abstract

The invention discloses mixed cathode diachylon of a superbattery and a preparation method thereof. The diachylon is prepared by mixing the following raw materials in parts by weight: 100 parts of lead powder, 4-10 parts of sulfuric acid, 0.1-8 parts of organic binder, 0.1-2 parts of barium sulfate, 0.01-2 parts of hydrogen separating inhibitor, 1-7 parts of active carbon, 0.1-3 parts of heterodromous graphite, 0.05-1 part of acetylene black, 1-4 parts of humic acid, 5-15 parts of red lead, 12-21 parts of water and 0.1-0.2 part of short fiber. By adding the hydrogen separating inhibitor, the active carbon maintains high-performance capacitance characteristics, so that an electrode has high capacitance. In a part of charge state, the recycling service life of the superbattery is improved by more than 10 times compared with a common lead-acid storage battery.

Description

technical field [0001] The invention relates to the field of preparation of lead-acid storage batteries, in particular to super battery negative electrode lead paste. Background technique [0002] In the daily use of lead-acid batteries, due to improper use or charging environment that cannot meet the conditions of the battery, especially the working state of the hybrid battery, the battery will be undercharged and discharged for a long time, and the battery will eventually fail (PCL3). [0003] In order to solve this technical problem, the current lead-acid battery industry has innovatively developed the combination of supercapacitors with the advantages of existing batteries, so that the high power characteristics of supercapacitors and the high energy density characteristics of batteries can be concentrated. For example, patent application 2009102098751 discloses a supercapacitor battery. In this patent application, a granular capacitor electrode material is added to the ...
