Positive electrode for lithium ion battery and lithium ion battery |
| abstract |
Provided is a positive electrode for a lithium ion battery that realizes an increase in energy density and is capable of improving durability. A positive electrode for a lithium ion battery ( 21 ) has a positive electrode current collector ( 21 A) and a positive electrode mixture layer ( 21 B) formed on the positive electrode current collector ( 21 A). The positive electrode mixture layer ( 21 B) contains a lithium nickel composite oxide and a metallic phosphate that coats the lithium nickel composite oxide. The lithium nickel composite oxide is represented by a chemical formula LiNi x Co y M z O 2 (in the formula, M is one or more elements selected from the group consisting of Mn, Al, Mg and W, x+y+z=1 and 0.6≤x<1.0). The metallic phosphate is one or more materials selected from the group consisting of VPO 4 , VP 2 O 7 and VPO 4 F. The mass ratio of the metallic phosphate to the lithium nickel composite oxide is 0.01 mass % or more and 20 mass % or less. |
