Abstract
The present invention features a high-capacity anode material for rapidly chargeable and dischargeable lithium secondary batteries, which is composed of LiTiOnanoparticles. The LiTiOnanoparticles of the present invention exhibit excellent crystallinity and high rate capability compared to those synthesized using a conventional polyol process or solid reaction process by converting LiTiO, which is a zero-strain insert material spotlighted as an anode active material for lithium secondary batteries, into LiTiO, having a high crystalline nanostructure using a solvothermal synthesis process without performing additional heat treatment. The present invention also features methods of, and a method of preparing the high-capacity anode materials described herein.
