Space-Confined Synthesis of Yolk–Shell Structured Co3O4/Nitrogen-Doped Carbon Nanocomposites with Hollow Mesoporous Carbon Nanocages as Advanced Functional Anodes for Lithium-Ion Batteries

Abstract

Despite the high theoretical capacity as the anode material of lithium-ion batteries (LIBs), Co3O4 is subjected to rapid capacity decline and poor rate performance owing to its severe volume expans...
