چکیده
New generation lithium batteries require better performances, improved safety, and sustainability. Better performances can be obtained with anodes high-voltage cathodes, which in turn pose more pressure on the electrolyte stability, is mandatory for safety. Deep Eutectic Solvents (DESs) are promising components safer environmentally sustainable electrolytes. We investigate physico-chemical properties of DESs made 2,2,2-trifluoroacetamide (TFA) LiPF6. The best composition tested against Li metal two cathode active materials: LiFePO4 (LFP) high voltage LiNi1-x-yMnxCoyO2 (NMC). obtain good electrochemical performance a Li-metal cell LFP. Accelerated rate calorimetry shows thermal stability Li|DES|NMC respect to commercial liquid electrolyte.

متن کاملNovel semi-solid electrolytes for Li-based batteries
Electrolytes of relevance for high performance batteries have to fulfill a variety of restrictive criteria: Not only is high Li conductivity a necessary condition to avoid too high losses, also an anion contribution as low as possible is desired as otherwise concentration polarization occurs [1]. Furthermore, the electrolyte should be mechanically stable. Beyond that, it should wet the electrod...
