Abstract
Official abstract text for this publication.
Compositions comprising Type I clathrates of silicon (Si 46 ) or carbon (C 46 ) wherein the framework of the cage structure includes nitrogen and carbon or nitrogen and silicon or nitrogen-silicon-carbon atom type composition, with or without guest atoms in their respective cage structures. The clathrate structures are particularly useful for energy storage applications such as battery electrodes.
First claim
Opening claim text (preview).
What is claimed is: 1. A composition comprising a Type I clathrate of silicon having a Si 46 framework cage structure in the form of a battery electrode wherein the silicon atoms on said framework are at least partially substituted by nitrogen atoms, further including one or more guest atoms within said cage structure, represented by the formula A x N y Si 46−y where, A=H, Li, Na, K, Rb, Cs, Fr, Be, Mg, Ca, Sr, Ba, Ra, Eu, Cl, Br, I, and any metal or metalloid element, with 1<y<45 and x is the number of guest atoms within said cage structure wherein x has a value such that the cage structure undergoes a volume expansion of less than or equal to 50.0%. 2. The composition of claim 1 wherein A is Li. 3. The composition of claim 1 wherein said battery electrode comprises an anode electrode in a Li battery. 4. The composition of claim 1 wherein said battery electrode comprises a cathode electrode in a Li battery. 5. The composition of claim 1 wherein x is less than or equal to 200.
