Abstract

The invention discloses a manufacturing method of a positive plate of a fiber-type cadmium-nickel storage battery. The method comprises the following steps: (1) selecting a fiber nickel substrate; (2) preparing a nickel nitrate solution and a sodium hydroxide solution; (3) putting the fiber nickel substrate into a vacuum tank through a dipping rack, opening a vacuum pump to vacuumize the vacuum tank, opening a corresponding transfer valve to pump the nickel nitrate solution which is insulated in a dissolving tank into the vacuum tank by the vacuum pump after vacuumizing, closing a vacuum valve and opening an air inlet valve when an upper limit of the liquid level is reached; (4) closing the air inlet valve; (5) opening the air inlet valve, and introducing air into a nickel nitrate vacuum dipping tank, loosening a screw of the dipping tank, opening an upper cover, and hoisting the dipping rack; and (6) putting the dipping rack which is hoisted out from the nickel nitrate vacuum dipping tank into a mercerization tank by a crane, sequentially putting the mercerized dipping rack into four washing tanks by the crane and opening circulating water in the washing process; and (7) circulating the steps, measuring the increment in weight and finishing preparation after reaching the requirements. The manufactured positive plate has the advantages of high residual porosity, no fines removal, light weight and high charging efficiency.

Description

Technical field: [0001] The invention relates to a positive plate of a nickel-cadmium battery, in particular to a method for manufacturing the positive plate of a fiber-type nickel-cadmium battery. Background technique: [0002] Nickel-cadmium batteries can be divided into sintered nickel-cadmium batteries, bag-type nickel-cadmium batteries and fiber-type nickel-cadmium batteries according to the different forming processes of the plates. The positive plate of the existing nickel-cadmium storage battery has the disadvantages of low porosity, large weight, and low charging efficiency; and the service life is short, which is not conducive to the normal use of the nickel-cadmium storage battery. Invention content: [0003] The purpose of the invention is to design a method for manufacturing the positive plate of a fiber-type nickel-cadmium storage battery with reasonable technology and ideal use effect of the processed product. [0004] The technical scheme of the present in...
