Transition metal sulfide presents a big theoretical capacity,which might be one of anode materials of the next generation Li-ion battery.However,its capacity would suffer a sudden decrease due to the particle powdering,as the result of the serious expansion/contraction of electrode material during the charge/discharge process.Here three samples of iron/sulfur materials were prepared by sintering the flower-like micro/nano structural iron alkoxides under a mixed N_2 and H_2S atmosphere at 300,450 and 800 ℃.T...
