Beschreibung
Zusammenfassung:	This negative electrode for a lithium secondary battery is provided with a coating material in which a negative electrode active material layer and a current collector layer are joined, the negative electrode active material layer comprising aluminum, the current collector layer comprising a metal foil, and the negative electrode active material layer satisfying the following (1) and (2). (1) The average voltage of the negative electrode active material layer for a lithium alloying reaction measured using a lithium metal as a counter electrode of the negative electrode active material layer is 0.05 V or more, (2) the average voltage of the negative electrode active material layer for a lithium alloying reaction measured using a lithium metal as a counter electrode of the negative electrode active material layer is higher than the average voltage of the current collector, and (3) the average voltage of the negative electrode active material layer for a lithium alloying reaction measured using a lithium metal a
