Abstract
This application relates to an interface functional layer and a preparation method thereof, and a lithium-ion battery, where the interface functional layer includes a cyclic ether compound, a lithium salt, an auxiliary agent and a ceramic powder in a mass ratio of 50-90:5-30:5-40:0-5. In this application, the interface functional layer is provided between a positive and/or negative electrode and a solid electrolyte, thereby inhibiting the uneven deposition of lithium-ions at interfacial gaps, reducing the interface impedance, and meanwhile improving the interfacial stability.
