Fundamental Understanding of the Low Initial Coulombic Efficiency in SiOx Anode for Lithium‐Ion Batteries: Mechanisms and Solutions

To meet the ever-increasing demand for high-energy lithium-ion batteries (LIBs), it is imperative to develop next-generation anode materials. Compared to conventional carbon-based anodes, Si-based materials are promising due to their high theoretical capacity and reasonable cost. SiO
