Solid transition metal hydroxide film, solid transition metal hydroxide production method, and solid transition metal hydroxide production apparatus,

摘要

A transition metal hydroxide film with controlled orientation is provided. One aspect of the present invention is an α-type cobalt hydroxide film formed on a substrate, wherein the c-axis of the α-type cobalt hydroxide is substantially perpendicular to the surface of the substrate. It is in α-type cobalt hydroxide film. According to this configuration, an α-type cobalt hydroxide film with controlled orientation can be obtained, and a material that can be expected to improve various characteristics can be obtained. According to still another aspect of the present invention, there is provided an α-type cobalt hydroxide manufacturing method characterized in that α-type cobalt hydroxide is formed while increasing pH by dissolving ammonia gas in a cobalt ion solution. According to this configuration, α-type cobalt hydroxide can be obtained by a simple method.
