Oxygen vacancies boosted the electrochemical kinetics of Nb2O5-x for superior lithium storage

The introduction of oxygen vacancies (OVs) into Nb2O5 can not only provide more active sites for lithium storage but also change the electronic structure of Nb2O5 to boost electron/ion transport kinetics. Consequently, the defective Nb2O5-x exhibits high lithium storage capacity, superior rate capability, and cycling stability.

Automated summary

Introducing oxygen vacancies into Nb2O5 can enhance lithium storage capacity, improve rate capability, and cycling stability by providing more active sites and changing the electronic structure to boost electron/ion transport kinetics.
