Abstract
A composite anode active material including metal core particles and carbon nanotubes that are covalently bound to the metal core particles, an anode including the composite anode active material, a lithium battery employing the anode, and a method of preparing the composite anode active material.
Claims5
A method of preparing a composite active material comprising:
- preparing a mixed solution by mixing metal core particles, carbon nanotubes and an organic solvent;
- milling the mixed solution to form a milled mixed solution;
- and
- drying the milled mixed solution to form a dried product;
- and
- sintering the dried product in an inert gas atmosphere to arrive at a composite active material that is free of carbonaceous material except for the carbon nanotubes,
- wherein the organic solvent is an alcohol.
