Abstract
A metallic nanodendrite electrode and methods are shown. In one example, the metallic nanodendrite is coated with ruthenium oxide and is used as an electrode in a capacitor.
Claims9
An electrode, comprising:
- a mat of branched metal nanofibers on a nickel foam substrate;
- and
- a ruthenium oxide coating on an outer surface of the branched metal nanofibers.
A method of forming an electrode, comprising
- forming nickel nanowires on a nickel foam substrate;
- etching the nickel nanowires to form branched nickel oxalate structures;
- reducing the branched nickel oxalate structures to form branched nickel structures;
- and
- coating the branched nickel structures with ruthenium oxide.
