The reversible electrochemical intercalation of lithium occurs readily for a number of materials that act as positive electrodes, but the main choice for negative electrodes that act through intercalation has been graphite. Souza et al. (p. 2012) now report the low-potential, reversible intercalation of lithium into MnP4 at room temperature. Unlike other materials, the redox reaction occurs at the anionic site through the breaking and reforming of a P-P bond.
