▎ 摘  要

NOVELTY - Preparing metal lithium-carbon composite material comprises placing carbon micro-sphere and lithium metal in a sealed high-temperature reaction container, heating the high temperature reaction container, so that the lithium metal is converted into lithium steam and enters the microsphere gap and surface layer of the carbon microsphere; after the reaction is complete, cooling the high temperature reaction container, and obtaining the metal lithium carbon composite material of the lithium metal after the micro-sphere gap and surface layer has low temperature condensation. USE - Method for preparing metal lithium-carbon composite material, which is useful in lithium battery. ADVANTAGE - The material: can better suppress the formation and volume expansion of metal lithium dendrites during the cycle; and solves the problem of short cycle period and short cycle period caused by uneven deposition and dendrite growth caused by the large polarization of lithium metal anode under the action of high current density and low coulomb efficiency. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a lithium battery.
