There are many kinds of anode materials for lithium-ion batteries, and nano-tungsten oxide is one of the hotspots in the field of anode materials for next-generation lithium-ion batteries. This is because transition metal oxides such as nano-tungsten oxide-based materials have the advantages of relatively low price, wide sources and large specific capacity.

In addition, as a functional material, nano-tungsten oxide is also used in the production of photocatalytic materials (degrading organic pollutants, etc.), petroleum catalysts, electrochromic materials (smart glass), and gas-sensing materials (gas-sensing sensors).
