    摘要: A nonaqueous electrolyte secondary battery of an embodiment includes an electrode group including a cathode collector, a cathode having a cathode active material layer formed on the cathode collector, an anode collector, an anode having an anode active material layer formed on the anode collector, and a separator placed between the cathode and the anode, an exterior member housing the electrode group, and a nonaqueous electrolyte filled in the exterior member. In the nonaqueous electrolyte secondary battery, the anode collector is at least one metal selected from among Fe, Ti, Ni, Cr, and Al, or an alloy containing at least one metal selected from among Fe, Ti, Ni, Cr, and Al. In the nonaqueous electrolyte secondary battery, a coating containing at least one metal selected from Au and Cu is formed on at least one of the surfaces of the anode collector excluding the anode active material layer.

    摘要: A nonaqueous electrolyte secondary battery of an embodiment includes an exterior member; a positive electrode housed in the exterior member, a negative electrode containing an active material and housed in the exterior member so as to be spatially separated from the positive electrode via a separator, and a nonaqueous electrolyte filled in the exterior member. The negative electrode includes a negative electrode current collector and a negative electrode active material layer on the negative electrode current collector. A tensile strength of the negative electrode is 400 N/mm2 or more and 1200 N/mm2 or less. A peel strength between the negative electrode current collector and the negative electrode active material layer is 1.5 N/cm or more and 4 N/cm or less.
