 Context examples 

In addition to their high lithium transport rates, the niobium tungsten oxides are also simple to make.

(New class of materials could be used to make batteries that charge faster, University of Cambridge)

The niobium tungsten oxides used in the current work have a rigid, open structure that does not trap the inserted lithium, and have larger particle sizes than many other electrode materials.

(New class of materials could be used to make batteries that charge faster, University of Cambridge)

Although these materials, known as niobium tungsten oxides, do not result in higher energy densities when used under typical cycling rates, they come into their own for fast charging applications.
