| 摘要 |
Electrode active material of the invention is mainly an amorphous transition metal complex represented by AxMPyOz (where x and y are values which independently satisfy 0<=x<=2 and 0<=y<=2, respectively, and z=(x+5y+valence of M)/2 to satisfy stoichiometry; also, A is an alkali metal and M is a metal element selected from transition metals), and has a peak near 220 cm-1 in Raman spectroscopy. Applying the electrode active material of the invention to a nonaqueous electrolyte secondary battery increases the capacity of the nonaqueous electrolyte secondary battery.
