Flexible high performance lithium ion battery electrode based on a free-standing TiO2 nanocrystals/carbon cloth composite

Owing to high safety, low cost, nontoxicity, and environment-friendly features, LiFePO4 that is served as the lithium ion battery cathode has attracted much attention. In this paper, a novel 3D LiFePO4@C core-shell configuration anchored on carbon cloth is synthesized by a facile impregnation sol-gel approach. Through the binder-free structure, the active materials can be directly combined with the current collector to avoid the falling of active materials and achieve the high-efficiency lithium ion and electron transfer. The traditional slurry-casting technique is applicable for pasting LiFePO4@C powders onto the 2D aluminum foil current collector (LFP-Al). By contrast, LFP-CC exhibits a reversible specific capacity of 140 mAh·g-1 and 93.3 mAh·g-1 at 1C and 10C, respectively. After 500 cycles, no obvious capacity decay can be observed at 10C while keeping the coulombic efficiency above 98%. Because of its excellent capacity, high-rate performance, stable electrochemical performance, and good flexibility, this material has great potentials of developing the next-generation high-rate performance lithium ion battery and preparing the binder-free flexible cathode.

Enhanced Electrochemical Performance

Abstract Sodium vanadate have been widely used as a lithium-ion battery anode. However, its further application is restricted by the capacity attenuation during cycles because of its easy solubility in electrolyte, huge structural change, and low conductivity. Here, a lithium-ion battery electrode based on Cu-Cu2O coated Na5V12O32 nanowire arrays using a predischarge-electrodeposition method is freported. Remarkably, in the Cu-Cu2O@Na5V12O32 electrode, the Na5V12O32 nanowires function as the skeleton, and Cu-Cu2O nanoparticles function as the coating layer. At a specific current of 50 mA g-1, the composite electrode exhibits discharge and charge capacity of 837 and 821 mAh g-1 after 80 cycles, respectively, which is much higher than that of the Na5V12O32 nanowires electrode. This research provides a new pathway to explore electrode materials with enhanced electrochemical performance.
