Research on the smartphone charging is one of the most controversial in recent years. On the one hand we have those who want a lot of power but who do not count the deterioration of the charging cell; on the other hand we have those who prefer a less powerful and fast recharge and therefore want to keep their device healthy. Apparently a search forUniversity of Twentee can help both sides. Let's see how.
According to research from the University of the Netherlands in Twentee, there is a new material that charges the smartphone 10 times faster
Scientists from the University of Twente in the Netherlands they have made a technological breakthrough which could lead to the creation of batteries that charge significantly faster than their existing counterparts. The first tests they also demonstrate the durability of these elements. Such charging technology should be ideal for smartphones.
The modern ones Lithium-ion batteries, which are equipped with almost all mobile devices around us, have a cathode it's a anode in their structure. The new research focuses specifically on the anode. It is now made of graphite, which is why it cannot withstand ultra-fast charging and fails. Therefore, the scientists began to look for a new material for the anodes. This requires substances with porous structures at the nanoscale.

Current materials degrade smartphone battery performance with each cycle. Scientists at the University of Twente believe they were able to solve this using the nickel niobate. It has an open and regular crystal structure with identical repetitive ion transport channels.
Scientists integrated a nickel niobate anode into a charged battery and tested it performance. It was found that charges ten times faster than modern lithium-ion cells. In addition, the material is more compact than graphite, so it has a higher energy density - 244 mAh / g. Studies have shown that 81% of the capacity of this battery is maintained for 20.000 cycles without damaging the anode material. The production of nickel niobate is also much simpler than using other materials.
