چکیده
Organic, solid-state batteries require efficient solid electrolytes able to provide stable ion conduction. Here, based on ionic liquid (IL) polymers with chloride counterions as electrolyte materials for are presented. Acrylic monomers imidazolium substituents alkyl side groups that linked by spacers the acrylic group employed. The IL either converted thermally initiated radical polymerization into linear homopolymers or incorporated polymer networks UV-initiated copolymerization utilizing a bifunctional, non-ionic cross-linker. Both procedures successfully yielded desired materials, which is confirmed NMR spectroscopy (linear homopolymers) Raman (IL networks). conductivities at room temperature measured Electrochemical Impedance Spectroscopy. of in range 10−4 10−6 S cm−1, while those about two orders magnitude lower. They increase cm−1 70 °C. electrochemical stability examined Linear Sweep Voltammetry and proven voltage −2 +2 V. results reveal represent promising potential battery applications.

Electrochemistry of magnesium electrolytes in ionic liquids for secondary batteries.
The electrochemistry of Mg salts in room-temperature ionic liquids (ILs) was studied using plating/stripping voltammetry to assess the viability of IL solvents for applications in secondary Mg batteries. Borohydride (BH4(-)), trifluoromethanesulfonate (TfO(-)), and bis(trifluoromethanesulfonyl)imide (Tf2N(-)) salts of Mg were investigated. Three ILs were considered: l-n-butyl-3-methylimidazoliu...

In this study we investigated the chemical-physical properties of mixtures containing the protic ionic liquid (PIL) N-butyl-pyrrolidinium bis(trifluoromethanesulfonyl)imide (PYRH4TFSI), propylene carbonate (PC) and lithium bis(trifluoromethanesulfonyl)imide (LiTFSI) in view of their use as electrolytes for lithium-ion batteries (LIBs). We showed that these electrolytic solutions might display c...

Electrochemical capacitors (ECs) are electrical energy storage devices that have the potential to be very useful in a wide range of applications, especially where there is a large disparity between peak and average power demands. The use of ionic liquids (ILs) as electrolytes in ECs can increase the energy density of devices; however, the viscosity and conductivity of ILs adversely influence th...
متن کاملElectrochemical Model for Ionic Liquid Electrolytes in Lithium Batteries
Room temperature ionic liquids are considered as potential electrolytes for high performance and safe lithium batteries due to their very low vapor pressure and relatively wide electrochemical and thermal stability windows. Unlike organic electrolytes, ionic liquid electrolytes are molten salts at room temperature with dissociated cations and anions. These dissociated ions interfere with the tr...
