Patent ID: 7867654

Claim:
A nonaqueous electrolyte secondary battery comprising: a lithium-transition metal compound as a positive electrode active material that is capable of intercalating and deintercalating a lithium ion and is represented by Li 1+a Ni x Co y M z O 2 (wherein M is at least one element selected from Mn, Al, Ti, Zr, Nb, B, Mg and Mo; and 0≦a≦0.3, 0.1≦x≦1, 0≦y≦0.5, 0≦z≦0.9, a+x+y+z=1); and carbon as a negative electrode active material in a negative electrode active material layer that is capable of intercalating and deintercalating a lithium ion, wherein the negative electrode active material layer contains a powder of a compound having an imide bond.
