General description

Lithium hexafluorophosphate solution in ethylene carbonate and dimethyl carbonate is a class of electrolytic solution material 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.

Application

LiPF6 EC/DMC is widely used as an electrolyte that is thermally stable in solvents. It is mainly used in the fabrication of lithium-ion batteries.
Liquid electrolyte solutions play a key role in lithium ion batteries (LIB) acting as a 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.

Other Notes

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.

Articles

Dr. Sun reviews the recent advances in solid-state rechargeable batteries and cover the fundamentals of solid electrolytes in solid-state batteries, the theory of ion conduction, and the structures and electrochemical processes of solid-state Li batteries.

Li-ion batteries are currently the focus of numerous research efforts with applications designed to reduce carbon-based emissions and improve energy storage capabilities.

Lithium-ion batteries (LIBs) have been widely adopted as the most promising portable energy source in electronic devices because of their high working voltage, high energy density, and good cyclic performance.

The critical technical challenges associated with the commercialization of electric vehicle batteries include cost, performance, abuse tolerance, and lifespan.
