Abstract
Amorphous (mol %) powders were synthesized by mechanical milling treatment of starting materials SiO and SnO in a dry atmosphere at room temperature. The resultant powders were used in a rechargeable cell, Li/1 M ethylene For the first discharge at a current density of 1.5 mA the high capacity over 800 mAh was obtained for the potential range of 0 to 2.0 V vs. This first discharge capacity of amorphous powders was much larger than that of amorphous materials in the system obtained by mechanical milling reported previously. In addition, irreversible capacity of the former was smaller than that of the latter. The amorphous powders synthesized by mechanical milling treatments are one of the promising candidates as anode materials for lithium-ion secondary batteries. © 2001 The Electrochemical Society.
