a current collector; and
an electrode active layer on the current collector;
wherein the electrode active layer comprises at least one compound selected from the group consisting of compounds of formulae (I), (II), (III) and (IV):
Liy(M1)3-x1In2(PO4)3  (I)
wherein x1 is a number from greater than 0 to less than 3, y is a value such that charge neutrality of the formula is obtained, and M1 is at least one element different from Li selected from elements of groups 1, 2, 13 and a transition metal;
LiyIn2-x2(M2)x2(PO4)3  (II)
wherein x2 is a number from greater than 0 to less than 2, y is a value such that the formula (II) is charge neutral, and M2 is at least one element different from In selected from elements of groups 3, 5, 6, 8, 9, 11, 13, 16 and 17;
LiyIn2P3-x3(M3)x3O12  (III)
wherein x3 is from greater than 0 to less than 3, y is a value such that the formula (III) is charge neutral, and M3 is at least one element different from P selected from elements of groups 2, 3, 4, 5, 6, 7, 8, 9, 10, 14, 15 and 16;
LiyIn2P3O12-x4(X)x4  (IV)
