  Leading of Lithium-ion projects: development of electrode's process fabrication, electrolyte formulation and prototyping of Lithium-ion cylindrical cells. Achievements: 1. Cell technology for Ni- and Co-free cathode material was developed for 18650 formats with 175Wh/kg and +2500cycling. Technology includes electrodes parameters, fabrication processes (both, for cathode and anode) and own LiPF6-free electrolyte formulation. 2. A lot of different electrolyte formulations were developed based on LiPF6 salts as well as LiPF6-free for different cathode chemistries: - For LFP, developed electrolyte provides cycle stability at elevated temperatures; - For NMC, LMFP, LCO developed electrolytes provide cycle life improvement.
