摘要：
A lithium secondary battery includes a positive electrode, a negative electrode facing the positive electrode, a separator disposed between the positive electrode and the negative electrode, a nonaqueous electrolyte having lithium ion conductivity, and a spacer disposed between the negative electrode and the separator. Lithium metal deposits on the negative electrode during charging and the lithium metal dissolves from the negative electrode during discharging. The spacer has a plurality of spot-like projection portions.
