The present disclosure relates to novel compositions, electrodes, electrochemical storage devices (batteries) and ionic conduction devices that use cubic ionic conductor ("CUBICON") compounds, such as 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, a net charge of +n. The framework of this class of compounds can accept excess ions.
