Energy storage devices.

The market for production and consumption of lithium-ion rechargeable batteries is considered to be the most advanced developing market for independent energy sources. Lithium-ion rechargeable batteries are widely used in military equipment, medicine, measuring and computing devices, and household and industrial electronic devices. Despite the large volume of production of lithium-ion rechargeable batteries, the issue of increasing their efficiency and cost cuts is still very relevant as evidenced by a large number of publications and conferences related to this topic. In particular, this refers to the issues of improving the properties of electrode active materials, among which increase in capacity and number of charge/discharge cycles, as well as decrease in the degradation of materials during prolonged cycling should be underlined.

AkKo Lab continuously focuses on development of new and improvement of existing materials, suitable for creation of lithium-ion rechargeable batteries. The required high-tech equipment and many years of experience allow us to work on development and synthesis of electrode active materials, as well as on the assembly, testing, and cycling of the batteries.

Prototypes of lithium-ion rechargeable batteries with new types of cathode and anode highly energy intensive materials have been manufactured. Moreover, a new electrolyte based on environmentally friendly organic compounds capable of withstanding higher voltages as compared to modern analogs has been developed.

AkKo Lab employees developed and patented a new method for obtaining cathode nanomaterials LNMCO/C, in which the metal oxides are in the form of core/shell nanoparticles (<100 nm), where the shell is a layer of carbon that increases the electrical conductivity and stability of the electrode material. Using the transmission electron microscopy method, it was established that the thickness of the carbon layer did not exceed 5 nm, and the average crystallite size did not exceed 100 nm.

AkKo Lab is also successful in advanced researches, the results of which are patented, published in scientific journals, used to write and defend dissertations, and are presented at international scientific conferences.
