Yevgeny Kolesnikov, a researcher in the Department of functional nanosystems and high temperature materials of the National Research University of technology, said: "the compound cu0.4zn0.6fe2o4 porous nano microspheres we obtained as anode materials have three times the capacity of existing batteries on the market. At the same time, compared with other promising alternatives, the number of charge and discharge cycles has increased by four times. This improvement depends on the synergy between the special nanostructures and the elements used. "
Because of the use of spray pyrolysis, the synthesis of the final material can be completed in one step without intermediate steps. To this end, the scientists explained that the aqueous solution containing the required metal ions was transformed into fog by means of ultrasound, and then the solvent was evaporated and the original metal salt was decomposed at a temperature of up to 1200 ℃. As a result, micron or submicron spheres with the required porosity for operation in lithium ion systems were obtained.
