| Abstract Scope |
Gallium nitride (GaN) is a promising anode material for Li-ion batteries because of its high theoretical capacity (960 mAh/g), excellent chemical and thermal stability, low lithiation potential versus Li⁺/Li, and negligible volume expansion during cycling. However, the wide band gap of GaN results in low electronic conductivity, which limits ion and electron transport and consequently reduces its electrochemical performance. To address this limitation, MXene was incorporated into the GaN structure because of its nearly metallic electrical conductivity and excellent charge-transfer capability. In this research, GaN/MXene composite anodes with different mass ratios were fabricated to optimize the electrochemical performance of the system. By systematically varying the GaN-to-MXene ratio, we identified an optimal composition at a 4:3 mass ratio, which delivered a maximum specific capacity of 1254 mAh/g. The enhanced performance demonstrates that MXene effectively improves the electrical conductivity and electrochemical kinetics of GaN-based anodes, leading to significantly improved lithium-storage capability. |
