METHOD FOR MAKING ORGANIC METAL SKELETON MATERIAL EMBEDDED WITH NANOMETAL, LITHIUM-ION BATTERY ANODE MATERIAL AND ANODE-FREE LITHIUM-ION BATTERY

A method for preparing an organic metal skeleton material embedded with nanometal, comprising: S: making a precursor comprising a mixed solution of a metal salt and an organic ligand; S: providing an adjusting solution, mixing and causing reactions the adjusting solution with the precursor so that the adjusting solution makes the precursor mixed solution have a pH value ranged from 3 to 7, thereby forming an organic metal skeleton material; and S: dispersing the organic metal skeleton material in a hydrophobic solvent, then adding a metal salt solution, drying the organic metal skeleton material and the metal salt after adsorption, and causing a metal reduction reaction in a gas environment to form an internal organic metal skeleton material embedded with nanometals.
