Herein, we demonstrate a sustainable strategy for scalable production of α-Fe₂O₃ nanocrystals on flexible carbon textiles via controllable chemical bath deposition process. The assembly of α-Fe₂O₃ nanocrystals is densely anchored onto the carbon textiles, and the temperature-dependent mass loading and crystal size of α-Fe₂O₃ are systematically investigated. As an integrated electrode for lithium-ion batteries, the optimized Fe₂O₃@CTs with ultrathin three-dimensional interconnected porous architectures achieves significantly enhanced cycling performance and rate capability attributing to the improved stability, electronic interconnection, and shortened solid state diffusion pathway for Li⁺ ions/electrons. After the reactivation of the precursor, the Li-ion batteries based on the recycled Fe₂O₃@CTs exhibits electrochemical performance with no decay compared to that of the devices based on the fresh products. This sustainable methodology, considering material abundance, eco-efficiency, synthetic approach and scalability, is of crucial importance to both academy and industry for achieving high-performance lithium-ion batteries.

在这里，我们展示了通过可控制的化学浴沉积工艺在柔性碳纤维织物上可规模化生产α -Fe ₂ O ₃纳米晶体的可持续策略。将α -Fe ₂ O ₃纳米晶体的组装紧密地锚固在碳纤维织物上，系统地研究了温度随质量变化的载荷和α -Fe ₂ O _3的晶体尺寸。经过优化的Fe ₂ O ₃作为锂离子电池的集成电极用超薄三维连通多孔结构@CTs达到显著增强的循环性能和倍率性能归因于改善的稳定性，电子互连，和缩短的固态扩散路径为栗⁺离子/电子。在重新活化前体后，与基于新鲜产品的装置相比，基于回收的Fe ₂ O ₃ @CTs的锂离子电池表现出电化学性能，且无衰减。这种可持续的方法，考虑到材料的丰度，生态效率，合成方法和可扩展性，对于学术界和工业界对于实现高性能锂离子电池都至关重要。
