摘要：

In this study, we report TiO2-Fe2O3 nanocomposites as high-capacity negative electrode materials for rechargeable sodium-ion batteries with an ionic liquid electrolyte. The TiO2-Fe2O3 electrode in the Na [FSA] - [C(3)C(1)pyrr][FSA] (FSA = bis(fluorosulfonyl) amide; C(3)C(1)pyrr = N-methyl-N-propylpyrrolidinium) ionic liquid electrolyte at 363 K delivers a high reversible capacity exceeding 360 mA h g(-1) at a current density of 10 mA g(-1), exhibiting good rate capability and cycling performance.
