A facile hybrid assembly between Ti3 C2 Tx MXene nanosheets and (3-aminopropyl) triethoxylsilane-modified Si nanoparticles (NH2 -Si NPs) was developed to construct multilayer stacking of Ti3 C2 Tx nanosheets with NH2 -Si NPs assembling together (NH2 -Si/Ti3 C2 Tx ). NH2 -Si/Ti3 C2 Tx exhibits a significantly enhanced lithium storage performance compared to pristine Si, which is attributed to the robust crosslinking architecture and considerably improved electrical conductivity as well as shorter Li+ diffusion pathways. The optimized NH2 -Si/Ti3 C2 Tx anode with Ti3 C2 Tx : NH2 -Si mass ratio of 4 : 1 displays an enhanced capacity (864 mAh g-1 at 0.1 C) with robust capacity retention, which is significantly higher than those of NH2 -Si NPs and Ti3 C2 Tx anodes. Furthermore, this work demonstrates the important effect of the MXene-based electrode architecture on the electrochemical performance and can guide future work on designing high-performance Si/MXene hybrids for energy storage applications.

MXene与NH2-Si纳米粒子的混合组件，可提高锂的存储性能。

开发了Ti3 C2 Tx MXene纳米片和（3-氨基丙基）三乙氧基硅烷改性的Si纳米颗粒（NH2-Si NPs）之间的便捷混合组件，以构建NH2-Si NPs组装在一起的Ti3 C2 Tx纳米片的多层堆叠（NH2-Si / Ti3C2Tx）。与原始Si相比，NH2-Si / Ti3 C2 Tx的锂存储性能显着增强，这归因于强大的交联结构和显着改善的电导率以及更短的Li +扩散路径。Ti3 C2 Tx：NH2 -Si质量比为4：1的优化NH2-Si / Ti3 C2 Tx阳极显示出增强的容量（0.1 C下为864 mAh g-1），并且具有强大的容量保持能力，这明显高于NH2-Si NPs和Ti3 C2 Tx阳极。此外，
