摘要

Samples of small particle size bismuth and electroplated Ni-Sn alloy were tested as anodes for lithium ion batteries to highlight the effects of volume changes during charge and discharge on the cycling life of th electrodes. Bismuth was used for its relatively "high" potential of Li-Bi alloys formation (0.8-0.6V) which prevents other components within the electrode from being electrochemically active versus lithium in this potential window.
