China best top 5 sodium ion battery electrolyte manufacturers
Sodium-ion batteries are mainly composed of four parts: cathode material, anode material, separator, and electrolyte. The electrolyte is mainly responsible for conducting conductive ions between the positive and negative electrodes, and plays a key role in the energy density, cycle life, power density, safety performance, and wide temperature application.
There are many excellent sodium ion battery electrolyte manufacturers in China. This article compiles the list of the China best top 5 sodium ion battery electrolyte manufacturers, including DFD, NATRIUM, CAPCHEM, RTXC and LiFUN, hoping to help you have a deeper understanding of the sodium ion battery electrolyte development track.
The main components of sodium ion battery electrolyte
The main components of the electrolyte for sodium-ion batteries are raw materials such as solvents, solutes and additives, which are prepared in proportion under certain conditions.
Solvent: It is mainly used as a transport carrier for lithium ions, and carbonate solvents are commonly used. Including propylene carbonate (PC), ethylene carbonate (EC), diethyl carbonate (DEC), dimethyl carbonate (DMC), ethyl methyl carbonate (EMC), etc. When using, a mixture of high and low viscosity solvents is generally used, and the common combinations are EC+DEC, EC+DMC, EC+DMC+EMC, EC+DMC+DEC, etc.
Solute: As a provider of sodium ions, sodium hexafluorophosphate (NaPF6), sodium perchlorate (NaClO4), etc. are generally used.
Additives: Substances with specific functions. The electrolyte generally contains a variety of additives, which are divided into film-forming additives, high/low temperature additives, overcharge protection additives, flame retardant additives, rate-type additives, etc. according to their functions. The common ones are vinylene carbonate (VC) and fluoroethylene carbonate (FEC).
