Abstract
A nonaqueous electrolyte battery includes a case, a nonaqueous electrolyte provided in the case, a positive electrode provided in the case, and a negative electrode provided in the case, including a negative electrode active material and an electronic conductor containing a carbonaceous material, wherein a negative electrode working potential is nobler at least 1 V than a lithium electrode potential, and the carbonaceous material has a spacing (d002) of (002) plane of 0.344 nm or more and 0.352 nm or less, and a crystallite size (Lc) in the C-axis direction of 10 nm or less.
