Punched metal with a two-dimensional structure, expanded metal with a three-dimensional structure, metal mesh, foamed nickel or nickel fiber mat, etc. are used.
二次元構造のパンチングメタルの場合、その集電効率は
高く、又取り扱いも便利であるが、保持体の高多孔度化
を図ると金属支持体が二次元構造のため焼結基板の機械
的強度が極端に低下してしまうといった問題があった。In the case of punched metal with a two-dimensional structure, its current collection efficiency is high and it is convenient to handle, but if the holder is made to have a high porosity, the mechanical strength of the sintered substrate will be reduced because the metal support has a two-dimensional structure. There was a problem in that the amount of water was extremely low.

体を充填し焼結するといった方法も考えられていた。Further, in the case of foamed nickel or the like having a three-dimensional structure, it is excellent as a material for the active material holder in terms of high porosity and weight efficiency. However, it is not possible to connect the current collector when the battery is left in its original state, and therefore, a portion of the filled active material has generally been removed. Alternatively, a method has been considered in which metal powder is filled in predetermined locations of a foamed nickel holder and sintered in order to directly form a portion that will serve as a current collector terminal on the nickel foam holder.

った。However, if a part of the filled active material is removed in order to weld the current collector terminal, the current density becomes non-uniform and the current collection efficiency decreases, resulting in a decrease in the electrode plate utilization rate. Moreover, it was also inconvenient to handle during the manufacturing process.

。Furthermore, in a method of filling a predetermined portion of the holding body with metal powder, it is difficult to sufficiently fill the inside with metal powder, resulting in a decrease in electrical conductivity in this portion. The decrease in electrical conductivity has caused serious performance defects such as insufficient electrochemical reaction of the active material, leading to a decrease in the utilization efficiency of the active material, or poor charge/discharge characteristics.

填してなることを特徴とするものである。The present invention was invented in view of the above-mentioned problems, and it has good current collection efficiency at the welded part of the current collector as when using a metal support with a two-dimensional structure, and is easy to handle. The aim is to manufacture electrode plates for alkaline storage batteries that are convenient for use in sintered substrates and electrode plates while also maintaining three-dimensional structural strength. The metal support is rolled into a predetermined width and then sintered in a reducing atmosphere to form a sintered substrate, and the rolled portion of the sintered substrate is the welded portion of the current collector. In addition, the sintered substrate is filled with an active material.

構造の強度を維持していることが可能である。(2) Once the method described above is applied, the rolled portion of the sintered substrate becomes highly densified with nickel, and can be regarded as approximately equivalent to a nickel plate. Therefore, sufficient welding strength of the current collector can be obtained, and the current density will not become uneven even in the welded part of the current collector, and the strength of the three-dimensional structure of the electrode plate can be maintained. It is possible.

ている。In this embodiment, an expanded metal (of which the diagonal length of the hole is 2 cranes and 5 cranes, respectively) is used as the metal support.

Rolling is carried out at u (the rolled part 2 is shown with diagonal lines in Figs. 1 and 2), where the pressure for rolling is 3 ton/
CD was set because if the pressure is less than 2 tons/-, the welding part of the current collector to be obtained is unsatisfactory due to insufficient rolling.In other words, the rolled part 2 will not be in the shape of a nickel metal plate, This is because pores are generated and these pores are filled with active material in a later step, making it impossible to effectively weld the current collector. On the other hand, if the pressure is 5 tons/- or more, the expanded metal 1 will be distorted or cracked due to excessive pressure.

In the case of an anode, the anode is filled with nickel active material by sintering in a reducing atmosphere, followed by heat treatment in air, then immersed in an aqueous nickel nitrate solution, dried, and then treated with alkali. On the other hand, when used as a cathode, it is impregnated with cadmium salt. Next, the expanded metal 1 is cut along the boundary between the rolled portion 2 and the normal thickness active material holding portion 3 to obtain a scraper plate 4 as shown in FIG.
