Abstract
Embodiments of the present application disclose a lithium-ion battery and an electric device. The lithium-ion battery includes an electrolyte including a metal ion, where a reduction potential of the metal ion is higher than a reduction potential of a lithium ion; and a low CB value region, where a CB value of the lithium ion in the low CB value region satisfies: 0<CB<1, and the CB value is a ratio of a capacity of a negative electrode active material per unit area to a capacity of a positive electrode active material per unit area. The lithium-ion battery provided in the present application can effectively solve the problem of lithium deposition in the low CB value region.
