| 1. A method for producing an electrochemical electrode comprising a conductive substrate and an active layer formed on the
conductive substrate, wherein
(1) the active layer comprises a nickel-containing nanostructured material having a dendritic structure formed by agglomerating
a plurality of primary particles, and
(2) each primary particle comprises a core and a shell surrounding the core wherein the core is formed of a nickel nanocrystal
and the shell is formed of a nickel oxide film;
(3) the method for producing such an electrochemical electrode comprising:
Step 1 of obtaining nickel nanocrystal particles,
Step 2 of obtaining primary particles by forming a nickel oxide film on the surface of each nickel nanocrystal particle, and
Step 3 of forming a dendritic structure by agglomerating a plurality of the primary particles by depositing the primary particles
substantially perpendicular to a conductive substrate,
wherein a magnetic field is applied substantially perpendicularly to the conductive substrate in Step 3.
