NONAQUEOUS ELECTROLYTE BATTERY, AND METHOD FOR MANUFACTURING NONAQUEOUS ELECTROLYTE BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte battery arranged by use of a negative electrode active material which enables the suppression of the self discharge and the increase in resistance and which is capable of occluding and releasing lithium at a potential of 0.78 V (vs. Li/Li) or higher.SOLUTION: A nonaqueous electrolyte battery 1 is provided according to an embodiment. The nonaqueous electrolyte battery 1 comprises a negative electrode 5. The negative electrode 5 has a negative electrode material layer 5b including a negative electrode active material capable of occluding and releasing lithium at a potential of 0.78 V (vs. Li/Li) or higher. The negative electrode 5 has a coating film formed on the surface of at least a part of the negative electrode material layer 5b; the coating film includes a compound having a propylene glycol skeleton given by the following formula (1). The content of the compound having a propylene glycol skeleton in the coating film is 2-40 μmol per gram of the negative electrode material layer 5b.
