Electrode materials for lithium-ion technology

Research and development

Research and development

The basic requirement to power batteries for EV is the maintenance of high specific power (high rate), which is necessary for car accelerations. Eliont LLC researches and develops new proprietary, low-cost lithium-ion electrode materials, focused on EV and industrial applications. Apparently these materials based on low cost non-deficient raw materials. Being especially intended for high-power applications, these materials have the increased electronic and thermal conductivity in volume. In course of our research activity under optimization of electrode materials properties we use own approaches allowing purposefully modify critical applicable properties. We base our approach on special techniques of the solid-state synthesis.

R&D department has four subdivisions: laboratories of chemical synthesis, physico-chemical researches, chemical analysis, and electrochemical measurements and testing. Currently R&D department situated in two-flour, 5200 sq. ft. fully accustomed building. The laboratory functioning began in January 2008.

R&D department collaborate with Russian academic institutes, such as Institute of Solid State Chemistry, Institute of High-Temperature Electrochemistry, Physic of Metals (all in Yekaterinburg, Russia) and Moscow Institute of Physical Chemistry and Electrochemistry. This collaboration allows us to receive access to the modern equipment and methods of research. Close contact with leader scientists of these institutions give us unique possibility to expand our research capabilities.

Own laboratories of Eliont LLC equipped by devices, focused to researches of chemical kinetics and physic-chemical properties of compounds. It includes TG/DTA equipment, the laser particle size analyzer, as well as BET specific area measurement unit, etc. Laboratory operates by equipment for cell assemble and test of both electric and electrochemical properties of electrode materials. Synthesis capabilities include different kind of milling equipment, as well as furnaces for thermal processes under controlled gas media. Chemical analytical service for products and raw materials characterization is under construction.

Our researches and pilot production

Lithium titanate. This is very prospective anode material. Its outstanding feature is that the change of volume at the complete discharge is less than 0.1 %. It is one of the reasons of unique stability of this material during cycling. Best samples provides up to 10000 charge-discharge cycles. Absolutely flat discharge curve is typical for lithium titanate. Disadvantage of a material is low both electrical and thermal conductivity that are an obstacle for application in power batteries. We have ready for production formula of this material modification, in which electroconductivity is increased at least five orders in comparison with conventional material and high density of a current of the charge necessary for the target application is achieved.
