Lithium batteries comprising: (a) an electrode comprising a material of the formula AaMb(XY4)cZd, wherein (i) A is an alkaline metal and 0 < a <= 9; (ii) M comprises a transition metal, and 1 <= b <= 3; (iii) XY4 is X'O4-XY'X, X'O4-y,Y''2y, X"S4, or mixtures thereof, where X' is P, As, Sb, Si, Ge, V, S, or mixtures thereof; X" is P, As, Sb, Si, Ge, V, or mixtures thereof; Y' is halogen, S, N, or mixtures thereof; 0 <= x < 3; and 0 < y <= 2; and 0 < x <= 3; and (iv) Z is OH, halogen, or mixtures thereof, and 0 <= d <= 6; and (b) a counter-electrode; and (c) an electrolyte comprising an alkyl and/or alkylene carbonate and a cyclic ester. Preferably, M additionally comprises at least one non-transition metal. Preferred embodiments include those having an olivine structure, where c = 1, and those having a NASICON structure, where c=3. |
