Abstract

To provide a negative electrode for a lithium ion battery having high energy density and excellent rapid charging characteristics. A negative electrode for a lithium ion battery, the negative electrode including a negative electrode current collector, a negative electrode active material layer formed on the surface of the negative electrode current collector, and a non-aqueous liquid electrolyte including an electrolyte containing lithium ions and a non-aqueous solvent, in which the negative electrode active material layer includes a negative electrode active material and voids, the voids are filled with the non-aqueous liquid electrolyte, and a proportion of the battery capacity based on a total amount of lithium ions in the non-aqueous liquid electrolyte existing in the negative electrode active material layer with respect to the battery capacity based on a total amount of the negative electrode active material is 3% to 17%.
