  "textContent": "A lithium secondary battery includes a positive electrode, negative electrode, a separator, and a nonaqueous electrolyte having lithium-ion conductivity. The positive electrode contains a positive electrode active material containing lithium. The negative electrode faces the positive electrode. The separator is disposed between the positive and negative electrodes. The negative electrode includes a negative electrode current collector. The negative electrode current collector includes a layer having a first surface, and protrusions protruding from the first surface. The first surface is a surface on which lithium metal is deposited during charge. The protrusions do not divide the first surface into parts.",
