Lithium secondary battery and method for manufacturing the same

A lithium secondary battery comprising a positive electrode, a negative electrode and a nonaqueous electrolyte, including:

• a negative electrode current collector;
• and
• a negative electrode active material layer disposed on the negative electrode current collector and containing negative electrode active material particles, negative electrode conductor particles, and a negative electrode binder,
• wherein the concentration of the negative electrode conductor particles in a surface layer of the negative electrode active material layer facing away from the negative electrode current collector is higher than the concentration of the negative electrode conductor particles in a center of the negative electrode active material layer, and
• wherein the difference between the concentration of the negative electrode conductor particles in the surface layer of the negative electrode active material layer facing away from the negative electrode current collector and the concentration of the negative electrode conductor particles in the center of the negative electrode active material layer is larger than the difference between the concentration of the negative electrode binder in the surface layer of the negative electrode active material layer facing away from the negative electrode current collector and the concentration of the negative electrode binder in the center of the negative electrode active material layer.
