【Domestic Papers】Multiscale Bridged and Synergistic Interface Engineering of Ga₂O₃@rGO as an anode for Lithium-ion Batteries

      Researchers from the Xi’an University of Science and Technology have published a dissertation titled "Multiscale bridged and synergistic interface engineering of Ga₂O₃@rGO as an anode for lithium-ion batteries " in Chemical Physics Letters.

Abstract

      Ga₂O₃ has been used as an anode for lithium batteries due to its high theoretical capacity. However, limited electronic conductivity and severe volume expansion limit its application. Herein, to circumvent these issues, we proposed to design multiscale interface of Ga₂O₃@rGO. It was synthesized to achieve superior multiplicative performance (218 mAh g⁻¹ at 5.0 A g⁻¹) and cycling performance (428.7 mAh g⁻¹ after 100 cycles at 100 mAh g⁻¹). These findings suggest that the nanoscale morphology of Ga₂O₃ and nanographene work together to promote electron transfer, ultimately enhancing the cycling stability of the composites.
