Abstract

To provide an electrode and a secondary nonaqueous electrolyte battery by using the electrode active material whose cycle property is improved. SOLUTION: Vanadium-phosphorous composite compound with ω -VOPO4 crystal structure is used as the electrode active material for the secondary nonaqueous electrolyte battery. The vanadium-phosphorous composite compound is shown on the basis of the composition of VOPO4 by general formula (I). AXV1-y My O1+δ 1 P1-z Qz O4+δ 2 (I) (A is at least an element selected from alkali metals and alkali earth metals that is preferably lithium. X corresponds the amount of an element A inserted in an lithium site. M is at least one element selected from a group consisting of Al, Fe, Ga, Bi, Sn, Cr, Cu, Zn, Mg, Ti, Ge, Ta, Mo, W, Nb, Ni, Mn and Co. Q at least one element selected from a group consisting of S, As, Si and Ge.).
