Abstract

PURPOSE:To improve the voltage characteristic of an alkaline storage battery during high-rate discharge by using as a core member for a porous nickel base plate, a punched metal which has a mean porosity of within a specified range and in which holes of two or more different sizes are provided in such a manner that holes nearer the lug are larger and holes more distant from the lug are smaller. CONSTITUTION:A punched metal which has a mean porosity of 30-55% and in which larger holes 2 are provided near a lug 1 and smaller holes 2 are provided distant from the lug 1, is used as a core member. As a result, the discharge voltage of an alkaline storage battery during high-rate discharge can be increased.

過言ではない。In general, sintered alkaline M batteries are widely used in many fields because they have a long life, high rate charging and discharging characteristics, and low-quality discharge characteristics. These characteristics are brought about by the porous nickel substrate (hereinafter referred to as the "substrate"), which has a high porosity of 75 to 85%, a large surface area, and is a good conductor as an active material holder. It is no exaggeration to say so.

The current collecting ability is better when the core material has a small porosity, and the bonding strength of the active material is stronger when the porosity is large.The current collecting ability and the bonding strength of the active material are contradictory.

。The object of the present invention is to create a punching metal used as the core material of the board by adjusting the pore area so that the holes closer to the ears are larger and the holes closer to the 11th part are smaller. By having pores with two or more levels of pores, the bonding strength and current collecting ability of the active material can be improved. The electric current at the time of discharge (1
The object of this invention is to further improve the voltage characteristics during discharge at a higher level than conventional alkaline M-electromagnets.
