Usage

General Description

1-Decyl-2,3-dimethylimidazolium bromide is a chemical compound often used in the field of chemistry, particularly in the creation of ionic liquids. Its ionic structure gives it unique properties such as high thermal stability, low vapor pressure, and the ability to dissolve a vast array of compounds. Due to these properties, 1-decyl-2,3-dimethylimidazolium bromide is often employed in numerous applications like catalysis, solvation, and separation processes, among others. Despite its efficient role, like any other chemical compounds, it requires caution in handling due to possible health implications. Its structure involves a longer hydrocarbon chain attached to an imidazolium ring, which contains two methyl groups and is balanced by a bromide counterion.

1-Alkyl-2,3-dimethylimidazolium bis(trifluoromethanesulfonyl)imide ionic liquids as highly safe electrolyte for Li/LiFePO4 battery

Several 1-alkyl-2,3-dimethylimidazolium bis(trifluoromethanesulfonyl)imide ionic liquids (alkyl-DMimTFSI) were prepared by changing carbon chain lengths and configuration of the alkyl group, and their electrochemical properties and compatibility with Li/LiFePO4 battery electrodes were investigated in detail. Experiments indicated the type of ionic liquid has a wide electrochemical window (-0.16 to 5.2 V vs. Li+/Li) and are theoretically feasible as an electrolyte for batteries with metallic lithium as anode. Addition of vinylene carbonate (VC) improves the compatibility of alkyl-DMimTFSI-based electrolytes towards lithium anode and LiFePO4 cathode, and enhanced the formation of solid electrolyte interface to protect lithium anodes from corrosion. The electrochemical properties of the ionic liquids obviously depend on carbon chain length and configuration of the alkyl, including ionic conductivity, viscosity, and charge/discharge capacity etc. Among five alkyl-DMimTFSI-LiTFSI-VC electrolytes, Li/LiFePO4 battery with the electrolyte-based on amyl-DMimTFSI shows best charge/discharge capacity and reversibility due to relatively high conductivity and low viscosity, its initial discharge capacity is about 152.6 mAh g-1, which the value is near to theoretical specific capacity (170 mAh g-1). Although the battery with electrolyte-based isooctyl-DMimTFSI has lowest initial discharge capacity (8.1 mAh g-1) due to relatively poor conductivity and high viscosity, the value will be dramatically added to 129.6 mAh g-1 when 10% propylene carbonate was introduced into the ternary electrolyte as diluent. These results clearly indicates this type of ionic liquids have fine application prospect for lithium batteries as highly safety electrolytes in the future.

An imidazolium-functionalized self-assembling calix[4]pyrrole

A calixpyrrole bearing a tethered imidazolium functional group was prepared in the form of its bromide salt. This compound was found to undergo self-assembly to produce supramolecular polymers, wherein both the bromide anion and the imidazolium cation are bound to the calixpyrrole core. This journal is
