The work of Oral scientists helped to double the capacity of lithium-ion batteries.
The use of vanadium pentoxide doubles the capacity and charging speed of the lithium-ion batteries, while reducing their costs and size. This was reported by the Ural Federal University, whose scientific team participated in this international project.
The capacity can reach 294 mAh/g, for comparison, the smartphone battery is 140-160 mAh/g.
However, this material has disadvantages: poor conductivity and rapid decomposition.
"To solve this problem, we inserted nickel atoms into the structure of the material using ion implantation," explained Ivan Zhidkov, head of the UrFU laboratory.
