Abstract: Provided are embodiments of a method of synthesizing nano scale electrode materials using an ultrafast combustion technique and nano scale electrode materials synthesized using the method. The method does not require a process of annealing reaction products required for synthesis of electrode materials or any other additional processes, such as cleaning, filtering, and drying processes, so that it can take only several seconds to several minutes to obtain a resultant product.

Abstract: The present invention features a high-capacity anode material for rapidly chargeable and dischargeable lithium secondary batteries, which is composed of Li4Ti5O12 nanoparticles. The Li4Ti5O12 nanoparticles 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 Li4Ti5O12, which is a zero-strain insert material spotlighted as an anode active material for lithium secondary batteries, into Li4Ti5O12, 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.
