Abstract: In an alkaline storage battery positive electrode, the surface of positive electrode active material particles is uniformly coated with a conductive agent and the alkaline storage battery positive electrode is capable of suppressing an increase in internal battery resistance. The method of fabricating includes: (A) fixing active material particles to a current collector, the active material particles containing, as a main component, nickel hydroxide coated with a conductive agent, the conductive agent containing, as a main component, at least one kind of cobalt compound selected from the group consisting of cobalt hydroxide, tricobalt tetroxide, and cobalt oxyhydroxide; and (B) reducing the cobalt atom in the cobalt compound such that the cobalt atom has an oxidation number of less than +2, by applying a reduction current in an electrolyte solution to the current collector to which the active material particles are fixed, after the step (A).

Abstract: The angular position of a notch (17) is determined on the basis of data provided by second notch detectors (24a) and (24b) and an encoder (25). A controller (38) turns a rotational arm (22) for angular displacement such that holders (26) and (27) are displaced in a circumferential direction B from the notch (17), and then the holders (26) and (27) hold a wafer (19). Since the holders (26) and (27) are in touch with edges in which the notch (17) is not formed, the first notch detector (23) is able to detect the notch (17) without difficulty. Thus the position of the wafer (19) relative to the rotational arm (22) does not need to be changed several times depending on positions at which the holders (26) and (27) hold the wafer (19), which is necessary in the prior technology. The aligner (20) touches parts, not including the notch (17), of the wafer (19) and is capable of adjusting the position of the wafer (19) in a short time.
