MXene-nanoflower composites as high-performance electrode materials toward solid-state lithium-ion batteries

The design and synthesis of a silicon-integrated MXene-based nanoflower (Si@NFs) architecture using a simple hydrothermal method and thermal treatment are reported in this study. The resulting hierarchical structure creates a multidimensional conductive network by fusing the superior conductivity and mechanical stability of MXenes with the high capacity of nanosilicon. Due to effective ion transport, interfacial contact, and volume expansion buffering, Si@NFs exhibit better cycling stability, as demonstrated by structural and electrochemical characterisation. The strong interface and structural integrity of the nanoflowers indicate high promise for future integration into all-solid-state lithium-ion battery systems, even though solid-state electrolytes are not directly incorporated in this study.
