ANTIMONY-BASED INTERMETALLICS AS NEW ANODE MATERIALS FOR LITHIUM BATTERIES

摘要

Recently, there has been great interest in the study of lithium alloys with the aim of finding new materials for the negative electrode of lithium batteries, as an alternative to carbonous materials. Tin-based alloys (or intermetallics) have received prominence due to the large reversible capacities. In particular, Fe-Sn~(1) and Fe-Sn-C~(2), Cu-Sn~(3) systems have been the subject of study as lithium strage materials for lithium batteries. Here, we evaluate the galvanostatic cycling behavior of antimony-based intermetallics, CoSb_3.
