Abstract
An electroactive material including an aluminum nanoparticle core and a nanoshell surrounding the aluminum nanoparticle core as well as its methods of use and manufacture are described.
Claims22
An electroactive material comprising:
- an aluminum nanoparticle core;
- a nanoshell surrounding the aluminum nanoparticle core.
A material comprising:
- a nanoshell of TiO2, wherein a maximum diameter of the nanoshell is between about 10 nm and 100 nm, and wherein a maximum thickness of the nanoshell is between about 1 nm and 10 nm.
A method comprising:
- placing an aluminum nanoparticle having an outer layer of alumina on its exterior surface in an acid bath saturated with TiO(OH)2;
- reacting the alumina present on the aluminum nanoparticle with the acid bath to produce water as a product;
- reacting the water with a titanium containing compound in the acid bath to precipitate TiO(OH)2 onto the exterior surfaces of the aluminum nanoparticle to form a nanoshell on the aluminum nanoparticle.
An electrochemical device comprising:
- a current collector;
- and
- an electroactive material electrochemically coupled to the current collector, wherein the electroactive material includes an aluminum nanoparticle core surrounded by a nano shell.
