Ionic Liquid Based Electrolytes for High-Temperature Lithium-Ion Batteries
Today, lithium-ion batteries (LIBs) are ubiquitous in mobile phones, laptops, and other portable devices. The research community strives to further improve the LIB to increase electric driving distance and efficiency of both hybrid electric vehicles (HEVs) and fully electric vehicles (EVs). Conventional LIBs need to be strictly temperature controlled, most often cooled, to ca. 30°C, to ensure a...
متن کاملIon dynamics in halogen-free phosphonium bis(salicylato)borate ionic liquid electrolytes for lithium-ion batteries.
This study was focused on the investigation of ion dynamics in halogen-free, hydrophobic, and hydrolytically stable phosphonium bis(salicylato)borate [P4,4,4,8][BScB] ionic liquid electrolytes for lithium-ion batteries. The structure and purity of the synthesized ionic liquid and lithium bis(salicylato)borate Li[BScB] salt were characterized using 1H, 13C, 31P, and 11B NMR spectroscopy. The Li[...
متن کاملElectrochemistry 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...
متن کاملThe Role of Dissolved Gas in Ionic Liquid Electrolytes for Secondary Lithium Metal Batteries
The effect of dissolved gas on the reversibility of a Li/Li electrode in an ionic liquid electrolyte was investigated. Lithium metal is a potential anode in lithium batteries. The ionic liquid electrolyte was saturated with argon, nitrogen, oxygen, air, or carbon dioxide and the coulombic efficiency for the reduction and reoxidation of lithium metal was measured. Secondary ion mass spectroscopy...
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...
