We have prepared V-Sn alloys by powder metallurgy process as a new negative electrode material for Lithium ion battery. The cycle life was significantly improved by formation of intermetallic compound V2Sn3. The V2Sn3 alloy showed a rechargeable capacity of ca.500mAh/g over 50 cycles in the charge/discharge range of 0-1.5V.
