Abstract
A three-dimensional nanobattery formed by individually wiring nanostructured electrodes and combining them with an electrolyte. Short, capped nanotubes termed ‘nanobaskets’ are formed by sputtering coating onto nanoporous templates. Metallic nanowires are grown by electrochemical deposition from the nanobaskets and through the template, making electrical contact with each nanobasket electrode. The same procedure can be used to fabricate both a battery anode and a battery cathode. A thin layer of electrolyte is placed between the two nanobasket electrodes, and electrical contact is made through the nanowires.
Claims29
A three-dimensional nanobattery, comprising:
- nanoporous substrates having a plurality of pores through said substrates, said pores having an edge at a surface of said substrates;

- a plurality of individually wired nanowires each passing through said pore of said substrate and into said internal cavity of said nanobasket respectively;
- and
- a layer of electrolyte intermediate of and in contact with external surfaces of said capped ends of said nanobaskets.
A three-dimensional nanobattery, comprising:
