According to one embodiment, a nonaqueous electrolyte battery includes a positive electrode (3), a negative electrode (4), and a nonaqueous electrolyte. The positive electrode (3) includes at least one oxide selected from the group consisting of a first oxide having a spinel structure and represented by Li x Ni 0.5 Mn 1.5 O 4 , a second metal phosphate having an olivine structure and represented by Li x Mn 1w Fe w PO 4 , and a third oxide having a layered structure and represented by Li x Ni y Mn z Co 1-y-z O 2 . The nonaqueous electrolyte includes a first solvent. The first solvent includes at least one compound selected from the group consisting of trimethyl phosphate, triethyl phosphate, tripropyl phosphate, tributyl phosphate, and fluorinated phosphate ester. |
