One-step synthesis of MOF-derived Ga/Ga2O3@C dodecahedra as an anode material for high-performance lithium-ion batteries

Abstract

A Ga/Ga₂O₃@C dodecahedron composite with a high specific capacity of about 542 mA h g⁻¹ after 200 cycles at the current density of 1000 mA g⁻¹ was synthesized by one-step hydrogen reduction. This hierarchical homogeneous structure combined the Ga, Ga₂O₃ and carbon frameworks (from Ga-MOF) to exhibit excellent electrochemical performance.
