Exploring novel electrode materials with high capacity, good cyclability, and low cost is very crucial for the development of lithium-ion batteries (LIBs). Herein, Fe-2(SO4)(3) anode material is synthesized by a facile solution calcination route with the assistance of melamine. The Fe-2(SO4)(3) sample synthesized with the assistance of melamine exhibits much superior high-rate capability (with a reversible capacity of 621 mA h g(-1) at 5.0 A g(-1)) and long-term cyclability (maintaining a reversible capacity of 755 mA h g(-1) after 600 cycles at 1.0 A g(-1)). Moreover, the Fe-2(SO4)(3) sample displays significant pseudocapacitive behavior during the discharge/charge processes; the lithium ions diffusion coefficient is evaluated to be in the range of 10(-11) similar to 10(-13) cm(2) s(-1).
