Abstract

The invention belongs to the technical field of alkaline power batteries and in particular relates to a positive pole piece of a capacitance type nickel-hydrogen power battery, a preparation method of the positive pole piece and a battery prepared by the positive pole piece. Slurry of a positive pole battery is prepared from the following raw materials: zinc ball doped nickel hydroxide, ultrafine cobalt powder, titanium dioxide, PTFE (Polytetrafluoroethylene) emulsion, carbon-containing ultrafine nickel powder and an HPMC (Hydroxy Propyl Methyl Cellulose) binding agent. According to the positive pole piece provided by the invention, an oxygen evolution potential of a positive pole can be improved and the generation of oxygen is reduced; the invention further provides the preparation method of the positive pole piece and the battery prepared by the positive pole; under a normal-current charging state, the battery has no oxygen evolution and can be continuously subjected to floating charge; free maintenance of the capacitance type nickel-hydrogen power battery in a utilization process is realized; the historical technical difficulty that the service life of the battery is short, caused by zinc dendrites, is solved.

Description

technical field [0001] The invention belongs to the technical field of alkaline power batteries, and in particular relates to a positive pole piece of a capacitive nickel-hydrogen power battery, a preparation method thereof and a battery prepared by the same. Background technique [0002] In high-latitude areas, high-altitude mountainous areas or cold winters, vehicles that use lead-acid batteries as starting power often face difficulties in starting or fail to start the fire directly, and need to be heated separately to start the power supply or not turn off the standby state; while lead-acid batteries are used as vehicles. The power supply of communication base stations is often faced with freezing in winter, and the inability to work normally leads to intermittent or even direct interruption of the signal, and frequent maintenance is required, and the maintenance cost in these areas is more than ten times that of lead-acid batteries. Therefore, it is a realistic industria...
