High-performance Si@C anode for lithium-ion batteries enabled by a novel structuring strategy

Abstract

Si anode has drawn ever-growing attention because of its features of a large specific capacity, low electrochemical potential and high natural abundance. However, it suffers from severe electrochemical irreversibility due...

Interfacial engineering of Si anodes by confined doping of Co toward high initial coulombic efficiency

“…This observation indicates that the introduction of cobalt can accelerate the electron transport and lithium-ion diffusion rate. 29…”
