Influence of Zn Doping on Novel Cathode Material LiFePO4

1Introduction The novel cathode material LiFePO4 for lithium ion battery is considered as the substitute of LiCoO2 because of its high theoretical capacity, environmental benignancy and inexpensive cost[1,2]. But it is restricted by its low conductivity, the traditional ways to improve are carbon coating[3,4] and heteroatom doping[5-7].In this paper, we introduced the Zn as heteroatom and investigated the improvement by Zn doping.
