1-Ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide
EMIM TFSI, also known as EMIM NTf2, is a hydrophobic room-temperature ionic liquid of the imidazolium family, valued for low viscosity, high conductivity, and a wide electrochemical window.
Battery electrolyte
A battery electrolyte is the ion-conducting medium between a battery's two electrodes, carrying ions during charge and discharge, ranging from sulfuric acid to organic solvents.
Chunbo
Chunbo Co., Ltd. is a South Korean fine-chemicals company, established in 2007 and headquartered in Chungju, that makes lithium salts and additives for battery electrolytes.
Concentrated electrolyte
A concentrated electrolyte is a battery electrolyte with salt so concentrated that anions join the solvation shell, changing interfacial chemistry and enabling higher-voltage lithium and sodium batteries.
Cyclic carbonate electrolytes
Cyclic carbonate electrolytes are lithium-ion battery electrolytes built on ethylene carbonate and propylene carbonate, whose ring structures dissolve salt and form the protective anode film.
Electrolyte additive
An electrolyte additive is a minor component, a few tenths of a percent to a few weight percent, dissolved in lithium-ion battery electrolytes to improve stability, cycle life, and safety.
Ether electrolytes for lithium–sulfur batteries
Ether electrolytes for lithium–sulfur batteries are liquid electrolytes built on ether solvents like DME and DOL, widely used because they dissolve polysulfides but suffer from the shuttle effect.
Fluorinated ether electrolyte
A fluorinated ether electrolyte is a battery electrolyte in which ether solvents carry carbon-bound fluorine, weakening lithium coordination and raising oxidation stability for lithium-metal, sodium-ion, and high-voltage cells.
Fluorine-free electrolyte
A fluorine-free electrolyte is a battery electrolyte in which no component contains fluorine, investigated to replace commercial LiPF6-based electrolytes over safety, environmental, and regulatory concerns.
High-concentration electrolytes
High-concentration electrolytes (HCEs) are battery electrolytes with salt levels typically 3 to 5 M, where anions enter the cation's solvation shell and change interphase chemistry.
High-entropy electrolyte
A high-entropy electrolyte (HEE) is a battery electrolyte, liquid, gel, or solid, that mixes multiple salts, solvents, or ions to raise disorder, improving ionic conductivity, interfacial stability, and cycling.
Ionic liquid electrolytes for lithium and sodium cells
Ionic liquid electrolytes are battery electrolytes in which the solvent is a room-temperature ionic liquid, offering nonflammability and high stability but suffering high viscosity and low conductivity.
Lithium bis(oxalato)borate
Lithium bis(oxalato)borate (LiBOB) is a thermally stable lithium salt, first patented in 1999, used in lithium-ion batteries as an electrolyte salt and film-forming additive that forms a protective electrode interlayer.
Lithium difluoro(oxalato)borate
Lithium difluoro(oxalato)borate (LiDFOB, also LiODFB) is a lithium salt, structurally between LiBOB and LiBF4, first synthesized in 2003 and used in lithium-ion battery electrolytes as a film-forming additive.
Lithium difluorophosphate
Lithium difluorophosphate (LiPO₂F₂, often abbreviated LiDFP) is an inorganic lithium salt used as an electrolyte additive in lithium batteries, where it forms protective films that suppress dendrites and improve high-voltage and low-temperature operation.
Lithium hexafluorophosphate
Lithium hexafluorophosphate (LiPF6) is an inorganic lithium salt used as the conducting salt in the electrolyte of nearly all commercial lithium-ion batteries, typically dissolved in carbonate solvents.
Lithium nitrate additive
Lithium nitrate (LiNO3) is an inorganic salt additive for lithium metal and lithium-sulfur batteries, decomposing at the lithium anode to form a protective solid electrolyte interphase.
Lithium tetrafluoroborate
Lithium tetrafluoroborate (LiBF4) is an inorganic lithium salt used as an electrolyte salt in lithium-ion batteries, studied as an alternative to LiPF6 for low-temperature use.
Lithium-ion battery electrolyte
The lithium-ion battery electrolyte is typically a lithium salt such as LiPF6 dissolved in organic carbonate solvents, carrying lithium ions between electrodes and forming the protective interphases that enable stable cycling.
Localized high-concentration electrolyte
A localized high-concentration electrolyte is a battery electrolyte made by diluting a concentrated lithium-salt electrolyte with a non-coordinating diluent, preserving concentrated-electrolyte interfacial chemistry at lower viscosity and cost.
Redox mediators in Li–oxygen batteries
Redox mediators (RMs) in lithium–oxygen batteries are soluble redox-active molecules or ions that shuttle charge between the insulating discharge product lithium peroxide and the electrode, lowering the charge voltage.
Sodium beta-alumina
Sodium beta-alumina is a family of layered ceramics in which sodium ions move rapidly through conduction planes, serving as the solid electrolyte in sodium-sulfur and ZEBRA batteries.
Sodium bis(fluorosulfonyl)imide
Sodium bis(fluorosulfonyl)imide, abbreviated NaFSI, is the sodium analog of LiFSI, a conducting salt in sodium-ion and sodium-metal battery electrolytes prized for high solubility and ionic conductivity.
Sodium hexafluorophosphate
Sodium hexafluorophosphate (NaPF6) is an inorganic sodium salt of the hexafluorophosphate anion and the benchmark electrolyte salt for sodium-ion batteries, though it hydrolyzes with moisture to form hydrofluoric acid.
Solid electrolyte interphase engineering
Solid electrolyte interphase (SEI) engineering is the deliberate design of the film that forms on a battery anode from electrolyte decomposition, aiming for stable, lithium-metal cells.
Solvent-in-salt electrolyte
A solvent-in-salt (SIS) electrolyte is a battery electrolyte in which salt outnumbers solvent, so anions enter the cation's solvation sheath; the aqueous variant is water-in-salt.
Superconcentrated electrolyte
A superconcentrated electrolyte is a battery electrolyte with salt concentrations above roughly 3 M, where ion pairing dominates and anion-derived films stabilize lithium-metal and high-voltage electrodes.
Vinylene carbonate
Vinylene carbonate, or 1,3-dioxol-2-one, is a cyclic carbonate and the most widely used electrolyte additive in lithium-ion batteries, introduced by Saft in 1994.
Water-in-salt electrolyte
A water-in-salt electrolyte (WiSE) is a highly concentrated aqueous battery electrolyte in which dissolved salt exceeds the water in weight and volume, first proposed in 2015 at the University of Maryland.
