Abstract

PURPOSE:To omit a drying process and retain the active material on a substrate by repeating a process in which nickel nitrate is melted and a porous sintered substrate is impregnated with it, then it is electrolytically reduced in an alkali aqueous solution and washed with water. CONSTITUTION:Nickel nitrate is melted at 100-110 deg.C and a porous sintered substrate is impregnated with it, then it is electrolytically reduced in an alkali aqueous solution and washed with water, and without drying it this impregnation process is repeated to produce a positive plate for a nickel cadmium storage battery. Therefore, nickel nitrate is changed to 3-hydroxide and the density is increased, thereby even though drying is not performed after the electrolytic reduction and water washing and water is contained in the porous substrate, substitution can be quickly performed and the active material can be retained, thus the process can be simplified and energy can be saved.

の製造法に関する。The present invention relates to a method for manufacturing a positive electrode plate for a nickel-cadmium storage battery using cadmium hydroxide as a negative electrode active material and an alkaline aqueous solution as an electrolyte.

結基板の多孔中に保持させる。The conventional manufacturing method for positive electrode plates is to first impregnate a sintered substrate of nickel powder with a solution of nickel nitrate, then electrolytically reduce the nickel nitrate in an alkaline aqueous solution to convert it into nickel hydroxide, and wash it with water to remove the alkaline content. Dry afterwards. This process is repeated several times as one cycle to hold a predetermined amount of live shellfish in the pores of the sintered substrate.

This is to allow the pores to be impregnated quickly with the nickel nitrate solution again. If water remains in the pores, the replacement of nickel nitrate will be slow, and even if it is replaced, the concentration of nickel nitrate will decrease due to the water in the pores. In order to quickly replace the moisture in the pores with nickel nitrate without reducing this concentration, the inclusion material Ni (N, On) y
We focused on the fact that the specific gravity of the impregnating solution should be set so as to reduce the number of moles of water hydrated in nHtO, that is, n, and to increase the difference in concentration between water in the pores and nickel nitrate.

結基板に含浸させるものである。That is, in the present invention, nickel nitrate is heated at 100 to 110°C.
It is made into a molten state (specific gravity 1.75 to 1.80) and impregnated into a porous sintered substrate.

発させることか可能である。As a result, nickel nitrate changes from the conventional hexahydrate to trihydrate and its concentration increases, so even if water is contained in the pores without drying, it can be replaced quickly (replacement is possible, and the immersion time can be reduced by drying). It is possible to use the conventional method.Since the impregnating liquid is at a high temperature, it is possible to partially evaporate the water contained in the pores in the impregnating liquid tank.

By omitting the
The industrial value of being able to reduce this to about 4 and eliminating the need for trenches and drying equipment is extremely great.
