Abstract
A solid oxygen-redox nanocomposite material including an alkali metal oxide, peroxide, or superoxide, or alkaline earth metal oxide, peroxide, or superoxide core, and a catalytic nanoshell or skeleton surrounding the cores, as well as methods of manufacture, are described. Additionally, sealed electrochemical devices including a solid oxygen-redox nanocomposite are also described.
Claims28
An electroactive nanocomposite material comprising:
- an electroactive core comprising at least one of an alkali metal oxide, peroxide, or superoxide, or an alkaline earth metal oxide, peroxide, or superoxide;
- and
- a nanoshell or skeleton surrounding the core.
A method of preparing an electroactive nanocomposite material, the method comprising:
- placing core particles in a solvent, wherein the core particles comprise at least one of an alkali metal oxide, peroxide, or superoxide, or an alkaline earth metal oxide, peroxide, or superoxide;
- placing a transition metal salt in the solvent;
- and
- precipitating a nanoshell or skeleton comprising a transition metal onto the particles to form a nanocomposite.
