Conventional current collectors in lithium-ion batteries (LIBs) are generally nonactive components. However, enhancing their electroactive properties and increasing the electroactive surface area can significantly improve the areal energy performance of next-generation battery electrodes. Herein, we introduce an electrochemically active textile current collector that delivers high energy storage performance, achieved through interfacial interaction assembly-induced electroplating. We first prepared metal nanoparticle/multiwalled carbon nanotube multilayer-incorporated cotton textiles using complementary interaction-mediated layer-by-layer assembly, and subsequently electroplated them with Cu. The resulting textile exhibited a high areal capacity of ∼3.27 mA h cm⁻² at 0.875 mA cm⁻², excellent cycling stability, and a strong energy recovery effect, thanks to the synergistic contributions of the large active surface area of the fibril structure, the robust interfacial assembly, and the formation of a metal oxide NP/pseudocapacitive polymeric gel-like phase at the electrode/electrolyte interface. Moreover, when incorporating Li₄Ti₅O₁₂ with a theoretical capacity of 175 mA h g ^− 1 into our textile current collector, the specific capacity and areal capacity of the LIB anode can be increased up to ∼573 mA h g ^− 1 and 8.60 mA h cm⁻² (at 15 mg cm⁻² LTO), respectively, outperforming those of previously reported LTO-based anodes.

锂离子电池 (LIB) 中的传统集电器通常是非活性元件。然而，增强它们的电活性和增加电活性表面积可以显着提高下一代电池电极的面积能量性能。在此，我们介绍了一种具有高储能性能的电化学活性纺织品集电器，该集电器通过界面相互作用组装诱导电镀实现。我们首先使用互补相互作用介导的逐层组装制备金属纳米颗粒/多壁碳纳米管多层掺入棉纺织品，然后用 Cu 电镀它们。所得纺织品在 0.875 mA cm ^-2时表现出高面积容量，约为 3.27 mA h cm ^-2，优异的循环稳定性和强大的能量回收效果，这归功于原纤维结构的大活性表面积，坚固的界面组装以及金属氧化物NP /赝电容聚合物凝胶状相的形成的协同贡献电极/电解质界面。此外，当将理论容量为 175 mA hg  ^{- 1的 Li} ₄ Ti ₅ O ₁₂掺入我们的纺织集电器中时，LIB 负极的比容量和面积容量可增加至 ~573 mA hg  ^{- 1}和 8.60 mA h cm ^-2（在 15 mg cm ^-2  LTO），分别优于先前报道的基于 LTO 的阳极。
