In Russia developed lithium-ion batteries with increased capacity and increased recharge cycle (2 photos)

The main problem for modern batteries andbatteries, powered by lithium-ion technology, are durability and energy storage capacity. The use of the latest nanomaterials created by scientists from the Technological University MISIS (NUST MISIS) will significantly increase the amount of energy accumulated in batteries and increase the number of battery charging cycles.

The non-material created at MISIS can replace graphite used for anodes in modern accumulators and electric batteries.

Today, despite numerousmessages about the creation of new promising technologies, namely, batteries using lithium-ion technologies are the main sources of energy in electric vehicles, household appliances, mobile computers and smartphones. According to Russian scientists, replacing the graphite in the anodes of lithium-ion cells with a new nano-material will increase the battery's "lifespan" by five times with a parallel increase in capacity by three times.

New material obtained by artificial means inlaboratory MISIS, has the formula Cu0.4 Zn0.6 Fe2O4. The material acquires these properties due to the combination of the properties of nanomaterials and the properties of individual components that make up the material.

To obtain a new substance usedfor the production of anodes, scientists applied the spray pyrolysis method. For this, a solution with metal ions is converted into fog using ultrasound, then water is evaporated at a temperature of 1200 degrees Celsius. The remaining microscopic porous metal spheres can be used for the production of anodes.

Checking the properties of the material produced inMISIS laboratories, was carried out by project partners from Seoul National University of Science and Technology (Republic of Korea), Norwegian University of Science and Technology (Norway) and SRM Institute of Science and Technology (India). Scientists have not announced plans to introduce the method on an industrial scale, but they are going to continue searching for materials suitable for replacing certain ineffective substances in batteries.
