Performance of Graphene and MXene Co-reinforced LiFePO4 Battery Cathode Materials
MXene/graphene@LiFePO4 composite cathode material was fabricated on the basis of the synthesis of MXene and graphene oxide.The structure of the composite cathode materials was characterized using techniques such as XRD,SEM and TEM,and its electrochemical properties were evaluated.The loading of MXene and graphene nanosheets can form a good conductive network and ion transport channel,and can simultaneously improve the electronic and ionic conductivity.For MXene/graphene@LiFePO4,it exhibited the highest initial discharge capacity of 163.6 mA·h·g-1 at 0.1 C,and the best rate performance with a high reversible capacity of 120.4 mA·h·g-1 at 10 C.Furthermore,the composite cathode material exhibited good cycling stability.
