Claim Text:
1. A method of preparing a high-capacity anode material for a rapidly chargeable and dischargeable lithium secondary battery using a solvothermal synthesis process, comprising the steps of: mixing a titanium compound and a lithium compound with only a polyol solvent without inclusion of water to form a mixed solution (step 1); putting the mixed solution into a reaction vessel lined with polytetrafluoroethylene (PTFE) (step 2) and then reacting the mixed solution at a predetermined temperature to produce a lithium-titanium oxide precipitate (step 3), wherein the predetermined temperature is in a range of 220 to 235° C. during the step 3; and washing (step 4), filtering (step 5) and then drying (step 6) at 120° C. the lithium-titanium oxide precipitate produced in the reaction vessel to obtain Li wherein the Li wherein the Li wherein the Li
