摘      要：P2-type layered oxide Na_(0.67)Fe_(0.5)Mn_(0.5)O_(2)is recognized as a very promising cathode material for sodium-ion batteries due to the merits of high capacity,high voltage,low cost,and easy ***,its unsatisfactory cycle and rate performances remain huge obstacles for practical ***,we report a strategy of SnO_(2)modification on P2-type Na_(0.67)Fe_(0.5)Mn_(0.5)O_(2)to improve the cycle and rate performance.
