Abstract
A flake Cu-Sn microcomposite alloy was prepared by a mechanical alloying technique for use as large volumetric capacity, highly compact negative electrode material for rechargeable lithium batteries. A 4 V lithium-ion cell based on such a Cu-Sn alloy anode and a 5 V cathode was tested. The preliminary results reported in this work show that the cell has an average working voltage at 4.0 V, and cycles well with a reversible capacity of ca. 200 mAh/g based on the pure Cu-Sn alloy when a cell was cycled between 3.5 and 4.6 V. © 2001 The Electrochemical Society.
