Abstract: nano FeS crystal has
stable structure and high ionic conductivity, but it is easy to form a by-product
in the process of reaction and cause some losses. So in order to improve the
performance of the battery of lithium ion batteries such as conductivity and
stability, the inhibitory effect of many by-products such as lithium sulfide,
using liquid phase precipitation method of Cu2+ doped FeS nano composite was
prepared by Fe (1-x CuxS), and assembled as anode materials for lithium ion
secondary battery two to test its electrochemical performance and the cycle
performance.
