In this paper we report on the behavior of some carbonaceous materials as anodes for Li ion batteries in several selected electrolyte solutions and over a wide range of temperatures, from -30掳 to 45掳. The solution components studied include alkyl carbonates (ethylene carbonate (EC), di-Me carbonate (DMC)) mono-fluorinated and bi-fluorinated ethylene carbonates (FEC, 2FEC), vinylene carbonate (VC), diglyme, LiPF6 and LiN(SO2CF3)2 (LiTFSI). While standard electrolyte solutions for Li ion batteries based on EC-DMC-LiPF6 have poor specific conductivity at low temperatures, diglyme/LiTFSI, VC (2%)-EC-DMC, FEC-DMC and 2FEC-DMC with LiPF6 exhibit reasonable conductivities (>2 mS/cm) at -30掳. Graphitic materials exhibit poor low temperature performance, while soft carbons behave better at low temperatures It was found that FEC-DMC/LiPF6 solutions are very suitable for carbon electrodes over a wide temperature domain. In fact, using these solutions enables soft carbon electrodes to demonstrate higher specific capacity than graphite electrodes below 0掳, although the room temperature specific capacity of graphite is 1.5 times higher than that of soft carbon. In the experiment, the researchers used many compounds, for example, 1-Methyl-1-propylpiperidin-1-ium bis((trifluoromethyl)sulfonyl)amide (cas: 608140-12-1Quality Control of 1-Methyl-1-propylpiperidin-1-ium bis((trifluoromethyl)sulfonyl)amide).
1-Methyl-1-propylpiperidin-1-ium bis((trifluoromethyl)sulfonyl)amide (cas: 608140-12-1) belongs to piperidine derivatives.Piperidine is a key saturated heterocyclic scaffold found in several of the top-selling small molecule pharmaceuticals and natural alkaloids, with a diverse range of biological activities. Fluorinated piperidines are also the subject of continued interest in medicinal chemistry, for example in the synthesis of selective dipeptidyl peptidase II (DPP II) inhibitors. Piperidine derivatives are also used in solid-phase peptide synthesis (SPPS) and many degradation reactions.Quality Control of 1-Methyl-1-propylpiperidin-1-ium bis((trifluoromethyl)sulfonyl)amide
