TECHNOLOGY FOCUS - INORGANIC CHEMISTRY - Preferred Composition: The composite anode active material further comprises a carbonaceous material. Preferred Components: The nanoparticle is present at 5-60 wt.% based on total weight of the composite anode active material. The nanoparticles have an average diameter of less than 300 mm. The metal capable of forming alloys with lithium comprises at least of silicon, tin, aluminum, germanium, lead, bismuth, antimony or its alloys. The matrix particles have: an aspect ratio of less than 5; major axis length of 10 mu m or less; and a spinel structure. The carbonaceous material is a low crystalline carbon or an amorphous carbon that has an interlayer spacing (d002) of 3.45 Angstrom or more. The titanium-containing precursor comprises at least one of titanium isopropoxide, titanium ethoxide, titanium propoxide or titanium tetrachloride. The lithium-containing precursor comprises at least one of lithium carbonate, lithium hydroxide, lithium chloride or lithium nitrate. The non-transition metal oxide comprises at least one of tin dioxide and/or silicon oxide compound of formula (SiOa) (II). The lithium titanate is of formula (LixTiyO4) (I).a = greater than 0 to less than 2;x = 0.8-1.4; andy = 1.6-2.2.    TECHNOLOGY FOCUS - ORGANIC CHEMISTRY - Preferred Components: The solvent comprises at least one of ethanol, methanol, isopropyl alcohol, butanol or pentanol. The mixed solution further comprises a carbon precursor. The carbon precursor comprises at least one of glycerol, erythritol, threitol, arabitol, xylitol, ribitol, mannitol, sorbitol, dulcitol, iditol, isomalt, maltitol or lactitol. Preferred Method: The sintering step is performed for 1-20 hours. EXAMPLE - 157.92 g Titanium isopropoxide was added to a dispersion prepared by dispersing 2.65 g powder of silicon nanoparticles having an average diameter of 50 nm in 800 ml ethanol and the mixture was stirred to prepare mixed solution. Then, 35 g distilled water was added to the mixed solution and was stirred for 2 hours to give pale gray solution. Acetone with a weight six times greater than that of the pale gray sol was added to the sol and centrifuged at 5000 rpm for 10 minutes, and solvent was removed to obtain precipitated powder (silicon nanoparticles coated with titanium hydroxide). The obtained powder was dried at 100 degrees C for 12 hours. The dried powder was kept in mixer including 32.84 g lithium carbonate to obtain a dried mixture. The dried mixture was kept in an alumina crucible, the temperature of the alumina crucible was raised up to 800 degrees C at a heating rate of 5 degrees C/minute in an inert atmosphere, and the dried mixture was sintered at 800 degrees C for 5 hours to obtain composite anode active material powder-type lithium titanate matrix particles with silicon nanoparticles dispersed therein and having a spinel structure.
