Abstract In this Full Paper we show that the use of lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) as conducting salt in commercial lithium‐ion batteries is made possible by introducing fluorinated linear carbonates electrolyte (co)solvents. Electrolyte compositions based on LiTFSI and were characterized regarding their ionic conductivity electrochemical stability towards oxidation with respect to ability form a protective film aluminum fluoride surface. Moreover, investigation...
Selective Pt and Co separation has been achieved, recycled Pt/C particles were synthesized, excellent electrochemical properties have observed.
Herein, we present an extensive physicochemical characterization of a series fluorinated and nonfluorinated carbamates their application as electrolyte solvents comprising lithium trifluoromethanesulfonyl imide (LiTFSI) conducting salt. In second step, these compositions were characterized with respect to ionic conductivity, salt dissociation, electrochemical stability toward oxidation. third selected electrolytes studied concerning ability enable the utilization LiTFSI in presence aluminum...
High barrier and mechanically resistant three-dimensional (3D) cellulosic objects were produced using cellulose nanofibrils (CNF) the molded process. The main objective is to improve properties of made by molding conventional papermaking fibers such as egg box. This well-known process, currently used for production low-end packaging, was simulated 3D-printed polycarbonate porous molds, dewatering, heat compression stages. CNF twin screw extrusion, which possess good transparency, base...
The development of high power Li-ion batteries is great relevance for hybrid electric vehicles (HEVs) technology. Electrochemical performance voltage cells operating with new fluorinated separators and ethylene carbonate - dimethyl 1M LiPF 6 electrolyte additives was evaluated according to the FreedomCAR DOE protocols simulate dynamic functioning in plug-in HEVs. results compared those commercial evidence beneficial impact separators. Acknowledgments Work partially funded by European FP7...
Aiming at increased performances for battery systems, lithium/sulfur technology (Li/S) is widely regarded as one of the most promising alternatives to lithium-ion systems. Although cyclability best Li/S current prototypes needs be further improved, potentially superior expected energy density (400-600 Wh.Kg -1 ) explains high attention that this has received over last 10 years. 1 Different studies 2,3 have pointed out both sulfur loading and utilization are required achieve capacity targeted...
