Summary:PROBLEM TO BE SOLVED: To provide: an electrode which can materialize a nonaqueous electrolyte battery showing a superior life performance even at a high temperature; a nonaqueous electrolyte battery showing a superior life performance even at a high temperature; a battery pack including the nonaqueous electrolyte battery; and a vehicle with the nonaqueous electrolyte battery installed therein.SOLUTION: An electrode is provided according to an embodiment. The electrode comprises a current collector and an electrode layer. The electrode layer is disposed on the current collector and includes a lithium fluoride. The content of the lithium fluoride to a weight of electrode layer is in a range of 0.02 wt.% or more and less than 2 wt.% in a thickness region ranging from an interface of the electrode layer and the current collector to 20% of a thickness of the electrode layer toward the inside of the electrode layer. The content of the lithium fluoride is 2-10 wt.% in a thickness region ranging from a face of the electrode layer on its backside up to 20% of the thickness of the electrode layer toward inside the electrode layer with respect to the interface of the electrode layer and the current collector.SELECTED DRAWING: None 【課題】 高温においても優れた寿命性能を示す非水電解質電池を実現できる電極、高温においても優れた寿命性能を示す非水電解質電池、この非水電解質電池を含む電池パック、及びこの非水電解質電池が搭載された車両を提供することを目的とする。【解決手段】 実施形態によると、電極が提供される。この電極は、集電体と電極層とを含む。電極層は、集電体上に配置されており、フッ化リチウムを含む。電極層の重量に対するフッ化リチウムの含有量は、電極層と集電体との界面から電極層内への電極層の厚さに対して20%までの厚さ領域においては、0.02重量%以上2重量%未満の範囲である。また、フッ化リチウムの含有量は、電極層と集電体との界面に対し、電極層の裏側にある面から電極層内への電極層の厚さに対して20%までの厚さ領域において2重量%以上10重量%以下である。【選択図】 なし
