Abstract
The invention relates to electrodes that contain active materials of the formula: NaaXbMcM′d(condensed polyanion)e(anion)f; where X is one or more of Na+, Li+ and K+; M is one or more transition metals; M′ is one or more non-transition metals; and where a>b; c>0; d≧0; e≧1 and f≧0. Such electrodes are useful in, for example, sodium ion battery applications.
