Tungsten oxide powder has been developed as an electrode material for new battery devices. The electron conductivity and lithium-ion diffusion of tungsten oxide powder can be improved to achieve ultra-fast charging and discharging. This material makes it possible to build battery devices with high power density. It enables smaller and lighter devices in areas such as energy regeneration and large current sources.

The size of fine powder is several μm, enabling the use in lithium-ion battery electrodes.

It has much greater capacity (energy density) and charge/discharge speed (power density) than conventional electric double layer capacitors.

 

It can be used in anode material for lithium ion batteries. One of the applications is on energy regeneration properties (elevators, micro/mild hybrid vehicles, trains). Applications requiring a large current or capacity (uninterruptible power supplies (UPS), large current sources, power supply stabilizers) can also make use of tungsten oxide.

 

The fast charging/discharging capacity also makes tungsten oxide a superb material in lithium-ion batteries in electric vehicles. Pure electric car is the trend, and several top vehicle manufacturers have launched their electric models. Toyota has electric vehicles (EVs) such as i-Road and iQ EV. Not only is there no need for a gasoline engine, but the battery has also been made more compact. Therefore, it creates an interior with space for four adult passengers and generates zero CO2 emissions during operation.

The ultra-fast charging and discharging feature of tungsten oxide making it an orientation of research in lithium battery, and many countries are embarking on the practice of the material. Experts said that the lithium-ion battery with electrode capacity made of tungsten oxide can be fully-charged as short as 10 minutes. This can solve one problem — the lack of power plant for electric cars.
