Descrição geral

Lithium hexafluorophosphate solution in diethyl carbonate is a class of electrolytic solution that can be used in the fabrication of lithium-ion batteries. Lithium-ion batteries consist of anode, cathode, and electrolyte with a charge-discharge cycle. These materials enable the formation of greener and sustainable batteries for electrical energy storage.
We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency. Find details here.

Aplicação

LiPF6 DEC is widely used as an electrolyte that is thermally stable in solvents. It can be mainly used in the fabrication of lithium-ion batteries.
Liquid electrolyte solutions play a key role in lithium ion batteries (LIB) acting as carrier of lithium ions between the cathode and anode. High purity and battery grade electrolyte solutions are thus crucial for lithium ion battery performance. The most common LIB electrolytes are derived from solutions of lithium salt, such as LiPF6 in non-aqueous solvents, example alkyl carbonates or solvent blend. The choice of the electrolyte solution is dependent on both the operating conditions like temperature and the nature of the electrode material in the LIB. The performance of the electrolyte solutions can be further modified with appropriate additives.
The ready-to-use electrolyte solutions are available in different solvent blends and can support a wide variety of lithium ion battery applications. These solutions are high purity and battery grade thus making them also suitable as standards in LIB research. Customized formulations can be made by inter-mixing the electrolyte solutions or by mixing appropriate of additives.

Outras notas

Handling instructions:
  • Do not use with glass equipment
  • All work should be done very quickly under dry air to prevent electrolytes from water uptake and solvent vaporization.
