LITHIUM SECONDARY BATTERY

A lithium secondary battery includes a positive electrode, a negative electrode, a lithium ion conductive nonaqueous electrolyte, and a separator disposed between the positive electrode and the negative electrode. On the negative electrode, lithium metal deposits during charging, and the lithium metal is dissolved during discharging; the negative electrode includes a negative electrode current collector, and a plurality of layers stacked on the negative electrode current collector; the plurality of layers include a first layer, a second layer, and a third layer; of the first to third layers, the first layer is closest to the negative electrode current collector, and the third layer is farthest from the negative electrode current collector; the first layer contains a material capable of storing lithium ions; the second layer contains lithium metal, and the third layer has an insulation property and a lithium ion permeability.
