Interlayer engineering of a V₂O₅ anode toward high-rate and durable dual-ion batteries

Abstract

Dual-ion batteries (DIBs) have gained widespread attention benefit from high operating voltage, little cost, and environmentally friendly. But the development of DIBs is dramatically limited by the unsatisfactory rate capacity...

Sodium ion pre-intercalation regulates the electron density and structural stability of vanadium oxide nanowires for Ca–ion batteries

“…Additionally, the slight shift of the V 5+ peak of NVO NW compared to the pristine V 2 O 5 NW is the evidence of the existence of oxygen vacancies. 50 Fig. 2b displays the O 1s spectra for both samples, revealing distinctive peaks at 531.8 and 530.3 eV.…”
