Sodium-ion batteries have received significant interest as a cheaper alternative to lithium-
ion batteries and could be more viable for use in large scale energy storage systems …

Sodium-ion batteries (NIBs) are a potential low-cost alternative to lithium-ion batteries for
large-scale energy storage, but many high-capacity NIB cathode materials undergo …

Na-rich transition metal oxides are promising cathode materials owing to their high
theoretical capacity and ability to be used in a solid-state sodium battery. However, one of …

Capacity and operating voltage are critical parameters of cathode materials that dictate the
energy density of lithium-ion batteries. Traditionally, redox reaction of the transition metal in …

Vanadium oxides exhibit promising characteristics for electrochemical energy storage,
owing to their capability to switch between different oxidation states, in combination with the …

Two sodium-rich transition metal (TM) oxides with the same spinel structure, Na 2 MoO 4
and Na 2 WO 4 have been investigated as cathode materials for Na-ion batteries for the first …

Abstract Knowledge of the equilibrium phase relationship in the V2O5–Na2O system is
critical and essential for the sodium salts roasting process of slag-bearing vanadium, and …

The authors regret an incorrect interpretation of the XPS and XANES spectra in Fig. 3a and b
of the original manuscript. The charge transfer mechanism during discharge was incorrectly …
