Patent ID: 7524584

Claim:
A battery, comprising: a positive electrode comprising a compound represented by the general formula: A a+b M C L I−d Z e+b+(V L )(d) , wherein: (i) A is selected from the group consisting of elements from Group I of the Periodic Table, and mixtures thereof; (ii) M includes at least one redox active element; (iii) L is selected from the group consisting of X′[O 4−x ,Y′ x ], X′[O 4−y ,Y′ 2y ], X″S 4 , [X z ′″,X′ 1−Z ]O 4 , and mixtures thereof, wherein: (a) X′ and X′″ are each independently selected from the group consisting of P, As, Sb, Si, Ge, V, S, and mixtures thereof; (b) X″ is selected from the group consisting of P, As, Sb, Si, Ge, V, and mixtures thereof; (c) Y′ is selected from the group consisting of halogens selected from Group 17 of the Periodic Table, S, N, and mixtures thereof; (d) 0≦x≦3,0≦y≦2,0≦z≦1; (iv) Z is selected from the group consisting of a hydroxyl (OH), halogens selected from Group 17 of the Periodic Table, and mixtures thereof, and V L is the oxidation state of composition variable L; and (v) a, b and e≧0,0<d<1, and c>0; (vi) wherein A, M, L, Z, a, b, c, d, e, x, y, and z are selected so as to maintain electroneutrality of the electrode active material in its nascent state; the battery further comprising a negative electrode; and an electrolyte.
