Abstract: | The xSnO·(100 ? x)B2O3 (0 ≦ x ≦ 80) glasses were successfully prepared by a mechanical milling technique. The glass with 40 mol% SnO showed the maximum glass transition temperature of 347°C. The SnO-B2O3 milled glasses consisted of both BO3 and BO4 units, and the fraction of BO4 units was maximized at the composition of 50 mol% SnO. The electrochemical properties of the milled glasses were examined using a simple three electrodes cell with a conventional liquid electrolyte. The glasses with high SnO content exhibited high charge capacities more than 1100 mAh g?1 and discharge capacities more than 700 mAh g?1 at the first cycle. The SnO-B2O3 milled glasses proved to work as anode materials for rechargeable lithium batteries. |
