Abstract

Amorphous CdGeP₂ is synthesized via eco-friendly high-energy ball milling and composited with different conductive carbons. The optimized CdGeP₂/graphene oxide exploits bimetallic reciprocal buffering capability and a fast electron-conductive network, delivering 981.5 mAh g⁻¹ after 100 cycles at 0.2 A g⁻¹ and 156.2 mAh g⁻¹ at an ultrahigh rate of 20 A g⁻¹.
