Oxygen Vacancies Boosting Lithium-Ion Diffusion Kinetics of Lithium Germanate for High-Performance Lithium Storage

Long Li et al.

Summary: Oxygen vacancies have been shown to enhance lithium-ion diffusion kinetics in Li2GeO3-x/C, leading to improved lithium storage. The introduction of oxygen vacancies increases electronic conductivity and reduces the activation energy of lithium-ion transport, resulting in accelerated lithium-ion diffusion kinetics during charging and discharging processes. The Li2GeO3-x/C nanofibers exhibit high discharge capacity, initial Coulombic efficiency, and rate capability, demonstrating the potential of injecting oxygen vacancies into metal oxides for high-performance anode materials.
