Amorphous materials in the system SnO-B2O3-P2O5, with or without the addition of Li2O, were synthesized by mechanical milling treatment of starting oxides in a dry N2 atmosphere at room temperature. These materials, obtained as fine powders, worked as an anode for a lithium-ion secondary battery using a conventional liquid electrolyte. The first discharge capacities of the anode of SnO-B2O3-P2O5 materials obtained by mechanical milling were more than 500 mAh g-1at a constant current of 1.5 mA cm-2. The capacity for Li2O added materials was comparable or slightly larger than that for the materials without the addition of Li2O. Charge-discharge curves obtained using these materials were similar to those for the glassy powders in the system SnO-B2O3-P2O5 prepared by a melt quenching procedure. SnO-based amorphous materials obtained by mechanochemical synthesis are promising candidates as high-capacity anode materials for lithium-ion secondary batteries.
