Mechanically Alloyed CdGeP2 Coupled with Optimized Conductive Frameworks for Ultrafast Lithium Storage

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 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 , which paves the way for realizing high-capacity ultrafast lithium storage.
