The present invention provides a carbon-lithium composite powder and a preparation method thereof. In the present invention, a carbon material is used as a skeleton to support metal lithium, which increases the specific surface area of the composite powder, and can effectively reduce the current density and stabilize the surface potential of an electrode, thereby effectively inhibit the growth of lithium dendrites during the process in which the metal lithium is used as an anode material. The present invention provides a method for preparing a lithium metal secondary battery electrode. In the present invention, a roller-press flaking process is adopted to prepare the electrode, such that it is easy to regulate the effective capacity of the metal lithium loaded on the current collector, thereby better matching the corresponding active cathode material to improve the effective utilization rate of the metal lithium.
A carbon-lithium composite powder, comprising a carbon skeleton and metal lithium coated on the surface of the carbon skeleton in composition, wherein the particle size of the carbon-lithium composite powder is 500 nm to 50 μm.
A method for preparing a lithium metal secondary battery electrode, comprising the steps of:
