An electrode active material comprising a compound of the formula A a+x M b P1-x Six O4 wherein (a) A is selected from the group consisting of Li, Na, K, and mixtures thereof, where 0 < a < 1 and 0 <= x <= 1; (b) M is M1e M2f M3g, wherein: a. M1 is a +2 oxidation state transition metal, where e > 0; b. M2 is a +2 oxidation state non- transition metal, where f > 0; c. M3 is a +3 oxidation state non-transition metal, where g > 0; and d. e + f + g = b. |
