Electrolyte solutions for electric double-layer capacitors

An electric double layer capacitor (EDLC) is an energy device that is expected to be deployed in applications such as backup power sources for portable devices, power sources used for momentary voltage drop compensation, as well as for automobiles, solar cells and fuel cells.
We are engaged in the production and sale of EDLC electrolytic solutions for containing SBP-BF4 (5-azoniaspiro [4.4] nonane tetrafurholoborate; a high-performance electrolyte with a characteristic structure) that has been dissolved within various solvents.
The KKE Series of electrolyte solutions using SBP-BF4 (which has a unique structure), is expected to provide higher performance and higher reliability when it comes to EDLC.

Features
SBP-BF4 structure
  • High solubility when it comes to various solvents. (PC at 3.5 mol/L; even dissolves in linear carbonates)
  • Features low viscosity and high conductivity when compared with standard quaternary ammonium electrolyte solutions.
  • Features high stability in relation to electrical and thermal elements.

Due to the unique structural characteristics involved, EDLC provides reduced internal resistance, temperature characteristics, high current charge/discharge, and improvements in reliability when compared to conventional quaternary ammonium electrolyte solutions (TEA-BF4, TEMA-BF4).
