Abstract:
A method for making lithium ion battery anode includes: scrapping a carbon nanotube array to obtain a carbon nanotube source, and adding the carbon nanotube source into water to form a carbon nanotube dispersion; providing a transition metal nitrate, adding the transition metal nitrate to the carbon nanotube dispersion to form a mixture of a carbon nanotube floccule and a transition metal nitrate solution; freeze-drying the mixture of the carbon nanotube floccule and the transition metal nitrate solution under vacuum condition to form a lithium ion batter anode preform; and, heat-treating the lithium ion battery anode preform to form the lithium ion battery anode.

Claim (Index 8):
The method of  claim 1 , wherein the step of heat-treating the lithium ion battery anode preform includes: placing the lithium ion battery anode preform in a heating furnace, adjusting a target temperature of the heating furnace to 250\u00b0 C. to 300\u00b0 C. under a heating speed of 0.5\u00b0 C. to 1.5\u00b0 C. per minute, and maintaining the target temperature for 3 hours to 8 hours.
