What are the true horizons for Lithium-Ion Batteries that can promote and advance the electro-mobility revolution in the 21-st century?
We develop the most energetic, high capacity cathodes for Li ion batteries, most suitable for use in electric vehicles. We focus on developments and modifications by cation (Al3+, Zr4+, Mo4+) and anion (F-) doping and surface coatings (Al2O3, AlF3, ZrO2) of materials for positive electrodes (cathodes) of two promising families of lithiated transition metals oxides: Li & Mn-rich xLi2MnO3·(1−x) Li[NiaCobMnc]O2 (x<1, a+b+c=1) and Ni-rich LiNixCoyMn1-x-yO2 (x→1) materials respectively. Our group has extensively worked on the above issues during the last 8 years, aiming at understanding:
A. How does the surface modification of Li & Mn-rich compounds can change the activation process during charging?
B. Capacity and voltage fading during cycling and stabilization mechanisms of the above important cathode materials.
Intrinsic properties of Ni-rich materials, like poor electronic conductivity, thermodynamic instability in charged state etc.
