Scientists unveil new titanium cathode material for metal-ion batteries

Scientists have introduced a new cathode material for metal-ion batteries. About this writes Nature with reference to the work of researchers from the Center for Energy Sciences and Technologies of Skoltech.

The rapid development of electric transport and renewable energy technologies now requires commercially available energy storage devices based on metal-ion batteries. Now the main disadvantage of these drives is the high price and a possible future cessation of lithium and cobalt-containing raw materials.

New type of battery

Scientists from Skoltech made cathode material based on titanium fluoride phosphate (KTiPO4F), a subspecies of one of the most common elements in the earth’s crust. Moreover, the material allows to achieve high energy performance and stable operation at high discharge currents.

“This is an exceptional result, literally shifting the established paradigm in the “battery community”, according to which titanium-based materials were considered exclusively as anode materials due to its low potential. We believe that the discovery of KTiPO4F may provide an incentive for the search and development of new titanium-containing cathode materials with unique electrochemical characteristics”.

Professor Stanislav Fedotov

In the future, the discovery can be used to create new types of batteries for scaling electric vehicles, scientists say.
