An object of the present invention is to provide a non-aqueous electrolyte cell capable of suppressing capacity drop and cell expansion. According to one embodiment, a nonaqueous electrolyte battery is provided. The nonaqueous electrolyte battery includes a positive electrode, a negative electrode, and a nonaqueous electrolyte. The negative electrode includes a negative electrode active material containing titanium oxide and has a coating film covering at least a part of the surface of the negative electrode. The coating film contains fluorine and satisfies the following formula (1). 0.2? F1 / F2? 0.8 ... (One) In the formula (1), F1 is a ratio (%) of fluorine atoms bonded to organic atoms among the fluorine atoms contained in the coating film, and F2 is a ratio of fluorine atoms bonded to metal atoms %)to be. |
