Russian scientists have developed a new cathode material for metal-ion batteries

A Russian research team from the Center for Energy Sciences and Technologies located at Skoltech managed to create a new cathode material, which was based on titanium fluoride phosphate. Thanks to this material, it was possible to achieve high, and most importantly, stable performance at increased discharge currents.

Scientists shared the results of the work done in a material published on the authoritative resource Nature Communications.

Why do we need new materials for batteries

Today, there is a hegemony of lithium-ion batteries, which use lithium and cobalt, which are quite expensive metals. And their stock (according to the latest data) is rather limited and is rapidly melting.

Therefore, scientists around the world are looking for an adequate replacement for expensive and rare components among the more common and cheaper ones.

The search led Skoltech scientists to obtain a potentially very promising material based on titanium fluoride phosphate (KTiPO4F), which possesses a sufficiently high electrochemical potential and can boast of ultra-high stability of functioning at increased charging rates and discharge.

Why titanium

The titanium material was not chosen by chance, because in terms of distribution it ranks 10th among all metals. At the same time, titanium-containing reagents are not only available, but also have increased stability and are completely non-toxic.

It would seem just an ideal candidate for replacing dangerous and expensive lithium. The only problem was that the titanium compounds used so far had extremely low electrochemical potential, which significantly limited the practical specific capacity of such battery.

But Russian scientists were able to overcome this barrier.

What are the prospects for invention

As S. Fedotov, the work done to create a new material for the anode based on KTiPO4F is an outstanding result, which in literally breaks the paradigm that titanium-based materials were previously considered anodic due to low potential.

The work done also shows that with sound skepticism and a competent approach, you can create new materials with the help of which materials with new, previously unknown ones will be created properties.
