| 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. |
