[claim9]
9. In claim 8,
The description above as for the process which combines,
LiX (in formula, X displays the halogen atom.)The 1st particle which consists of and,
M [x] O [y] (in formula, M the alkaline metal atom and the alkaline earths metal atom, the transition metal, the 12th family metal, and displays 1 where it is chosen from the metal of the 13th family element kinds at least, it is 0<x<=1 and 0<y<=2.)The process which is mixed with the 2nd particle which consists of, is included, production method of the positive electrode active material for the nonaqueous electrolyte accumulator.
[claim10]
10. In claim 9,
The description above the process which is mixed is done at rpm above 100rpm, production method of the positive electrode active material for the nonaqueous electrolyte accumulator.
[claim11]
11. Claim in 9 or 10,
You can obtain the blend where mean particle diameter is 100 .micro.m or less the description above with the process which is mixed, production method of the positive electrode active material for the nonaqueous electrolyte accumulator.
[claim12]
12. Claim either 9 or 11 in 1 sections,
The aforementioned 1st particle/the aforementioned 2nd particle (mass ratio) is the 100 or less of 0.1 or more, production method of the positive electrode active material for the nonaqueous electrolyte accumulator.
[claim13]
13. Claim either 9 or 12 in 1 sections,
M [x] O [as for y], B [a] A [b] O [c] (in formula, as for A, the alkaline metal atom and the alkaline earths metal atom, the transition metal other than B, the metal of the 12th family element, and they are 1 where it is chosen from the metal of the 13th family element kinds at least, B is the transition metal, is 0<a<=1, 0<=b<=1 and 0<c<=2.)So it is, production method of the positive electrode active material for the nonaqueous electrolyte accumulator.
[claim14]
14. Claim either 9 or 13 in 1 sections,
M [x] O [as for y], B [a] A [b] D [d] O [c] (in formula, as for A, the alkaline metal atom and the alkaline earths metal atom, the transition metal other than B, the metal of the 12th family element, and they are 1 where it is chosen from the metal of the 13th family element kinds at least, B is the transition metal, D is the transition metal other than A and B, is 0<a<=1, 0<=b<=1, 0<c<=2 and 0<=d<=1.)So it is, production method of the positive electrode active material for the nonaqueous electrolyte accumulator.
