Title:
ナノサイズの金属酸化物電極の製造方法
Document Type and Number:
Japanese Patent JP4552085
Kind Code:
B2
Abstract:
The present invention relates to a method for manufacturing a nano-structured metal oxide electrode, and in particular, to a method for manufacturing a metal oxide electrode having a few tens or hundreds of nanometers in diameter that is well adapted to an electrode of a supercapacitor using an alumina or polymer membrane having nano-sized pores as a template. Preferred methods for manufacturing a nano-structured metal oxide electrode comprises steps of preparing an alumina or polymer template having a plurality of nano-sized pores; sputtering a metal acting as a current collector with a few tens of mum of thickness in one surface of the alumina template; charging the template, after the sputtering step, by submerging it into a precipitation solution having a metal salt dissolved therein, and applying a static current or electrode electric potential thereby electrochemically precipitating a metal oxide in the nano-sized pores of the template; a step in which the composite of the alumina or polymer template and the metal oxide are contacted with a sodium hydroxide solution or other base to remove the alumina or polymer template; and an optional drying step to provide the nano-structured metal oxide electrode.
