Solvents

The solvent does the heavy lifting in any non-aqueous electrolyte: it sets the salt solubility, the operating temperature window, the SEI/CEI chemistry on reactive metal anodes, and — increasingly — the flammability profile of the cell. This collection groups the polar aprotic and ionic-liquid solvents that EChem Supplies stocks in battery-grade purity for lithium-ion, lithium-metal, sodium-ion, potassium-ion, magnesium, aluminum-ion, supercapacitor, and CO2-electroreduction work.

Products are organized by solvent family so you can pick by mechanism rather than by name:

Glymes and linear ethers

DME (1,2-dimethoxyethane) — short-chain ether, low viscosity, the workhorse co-solvent for Li-S, Li-metal, Na-metal, and Mg-ion electrolytes; pairs with high-concentration LiFSI/LiTFSI to form fluoride-rich SEIs.
Tetraglyme (G4) — chelating polyether that strongly coordinates Li+ and Na+, enabling solvate (sulfolane-free) ionic-liquid-like electrolytes and stabilising glyme-based Li-O2 chemistries.

Phosphate flame-retardant solvents

TMP (trimethyl phosphate) — non-flammable co-solvent and additive for safer LIB electrolytes; its phosphorus-radical scavenging suppresses the chain reactions that drive thermal runaway in carbonate baselines.

Imidazolium ionic liquids

[EMIM][DCA] — low-viscosity, high-conductivity IL widely used as a CO2RR co-catalyst and a transport-friendly supercapacitor solvent.
[EMIM][FSI], [BMIM][TFSI], [BMIM][PF6], [BMIM][BF4], [BMIM]Cl — hydrophobic and hydrophilic imidazolium variants spanning the FSI / TFSI / PF6 / BF4 / Cl anion series, for Li-ion safety additives, supercapacitors, electrodeposition, and Al-ion chloroaluminate baths.

Pyrrolidinium and piperidinium ionic liquids

Py13-FSI, Py14-FSI — pyrrolidinium FSI ILs prized for wide cathodic windows and excellent compatibility with Li-metal and Na-metal anodes.
PP13-FSI — piperidinium FSI IL with an even wider electrochemical window, used where Py-based ILs are reduced at the negative electrode.

If you are formulating a flame-retardant or high-voltage electrolyte, start with TMP or an FSI-based IL; for Li-S, Li-metal, and Na-metal cells, begin with the glyme/ether family; for CO2RR, supercapacitors, and Al-ion work, use the imidazolium series. Pair these solvents with the matched salt and additive lines in Electrolytes and Electrolyte Additives.
