CUBICON Materials that Outperform Lithium-Ion Batteries
The present invention relates to novel compositions, electrodes, electrochemical storage devices (batteries) and ionic conduction devices that use cubic ionic conductor ("CUBICON") compounds, preferably nitridophosphate compounds. The cubic ionic conductor compound have a framework formula [MT.sub.3X.sub.10].sup.n- (1) and a general formula A.sub.xMT.sub.3X.sub.10 (2), where M is a cation in octahedral coordination, T is a cation in tetrahedral coordination, X is an anion, and the framework has a net negative charge of -n, where a variable number of potentially mobile additional chemical species, A, can fit into the open space within this framework with a net charge of +n.
