What is vanadium used for?

1.1. Vanadium properties and applications Vanadium is primarily used as an additive to steel in the form of ferrovanadium (Moskalyk and Alfantazi, 2003). Around 85% of the vanadium produced globally is used for this purpose (Swinbourne et al., 2016).

Is sodium vanadium titanium phosphate a super ionic conductor?

Here we report a sodium super-ionic conductor structured electrode, sodium vanadium titanium phosphate, which delivers a high specific capacity of 147 mA h g −1 at a rate of 0.1 C and excellent capacity retentions at high rates.

Can vanadium-based compounds fill the gap in battery technology?

This is where vanadium-based compounds (V-compounds) with intriguing properties can fit in to fill the gap of the current battery technologies.

How to recover vanadium chromium and titanium from titanomagnetite ores?

Zhao et al. (2014) proposed an alternative method for the recovery of vanadium, chromium and titanium from titanomagnetite ores (Fig. 9). The ore is roasted under reducing conditions to selectively reduce iron. The iron is then removed by magnetic separation, and the non-magnetic material leached in hydrochloric acid.

How much vanadium is present in titanomagnetite?

The majority of vanadium in titanomagnetite deposits occurs as V 3+, with a small amount of V 4+. X-ray absorption near edge structure spectroscopy (XANES) of seven titanomagnetite samples from different locations has shown that only approximately 2–17% of the vanadium was present as V 4+ (Balan et al., 2006).

Can identifying impurities simplify the vanadium electrolyte supply chain?

Identifying which impurities have which effects could potentially simplify the vanadium electrolyte supply chain by enabling vanadium producers to remove deleterious impurities earlier in the process and tailor the end product to meet the needs of the battery producers.
