NOVELTY - The battery has a double-electrode, and an active anode formed on a surface of a metal nickel three-dimensional space structure. A layer of gel-state solid electrolyte is formed between a nickel oxide micro-electrode and a zinc micro-electrode. A polyimide material layer is formed on a surface of the structure. An active material of the anode is made of nickel oxide. A metal current collector is made of gold or nickel. A silicon substrate includes a silicon dioxide insulating layer. The electrolyte is made of potassium hydroxide, sodium carboxymethyl cellulose and polyvinyl alcohol.    USE - Three-dimensional miniature zinc-nickel battery for a micro-robot electronic intelligent system. Can also be used for a chemical sensor, baffle-field radio recognition equipment and a distribution baffle-field sensor.    ADVANTAGE - The polyimide material is formed on the surface of the metal nickel three-dimensional space structure, thus minimizing volume of the battery. The polyvinyl alcohol and the sodium carboxymethyl cellulose improve the moisture retention and mechanical performance of the polymer electrolytic film, and protect the electrolytic film from shrinkage and brittlement caused by deep dehydration. The electrolytic salt is dissolved in the electrolytic film, so as to improve the conductivity of the electrolytic film. The easy volatilization of the liquid electrolyte is prevented, and the service life of the micro-robot electronic intelligent system is improved. The battery is manufactured in a simple manner, and the productivity of the battery is improved. The battery is manufactured with high energy, better performance and wide application. The double-electrode is dipped into the compound electro-deposition reaction solution composed of nickel nitrate and nickel chloride, thus inducing steady current of the double-electrode.    DETAILED DESCRIPTION - The double-electrode is dipped into compound electro-deposition reaction solution composed of nickel nitrate and nickel chloride. An INDEPENDENT CLAIM is also included for a method for manufacturing a three-dimensional miniature zinc-nickel battery.    DESCRIPTION OF DRAWING(S) - The drawing shows a perspective view of a three-dimensional miniature zinc-nickel battery.
