Claim 9:
10. The preparation method according to claim 9, comprising the following step:
growing the lithium-containing conductive layer serving as the supporting framework in situ on surfaces of the lithium metal particles, to obtain the lithium metal composite electrode material;
under solvent-free and oxygen-free conditions, the lithium metal particles being in contact with a metal compound capable of reacting with lithium, to grow the lithium-containing conductive layer in situ on the surfaces of the lithium metal particles after reaction;
under solvent-free and oxygen-free conditions, mixing and grinding the lithium metal particles and the metal compound, and then performing heat treatment, to grow the lithium-containing conductive layer on the surfaces of the lithium metal particles in situ;
the metal compound having a mass percentage of from 20% to 50%, relative to a total mass of the lithium metal particles and the metal compound.
