A flame-synthesized TiO-based anode material was developed by conducting in-situ composition of TiO particles and amorphous carbon particles in a flame. The particle characteristics of the collected composite particles were subsequently examined, and the performances of lithium-ion secondary batteries that used these composite particles as anode materials were measured and evaluated. The aggregates of synthesized and collected particles were confirmed through SEM, EDS, and XRD analysis, revealing a mixture of amorphous carbon particles and TiO particles with ranging in size from about 40 to 80 nm. Analysis of the charge/discharge test results on these coin cells indicates that TiO and amorphous carbon determine capacity retention and discharge capacity, respectively. Considering both capacity and retention of the cells, optimal flame synthesis conditions were found.
