Popis: | Exploring novel electrode materials with high capacity, good cyclability, and low cost is very crucial for the development of lithium-ion batteries (LIBs). Herein, Fe2(SO4)3 anode material is synthesized by a facile solution calcination route with the assistance of melamine. The Fe2(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 Fe2(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 ∼ 10−13 cm2 s−1. |
