Technical information
1) Solubility
IL-C15 and IL-C17 show excellent solubility in PC compared to TEA-BF4, and are fairly soluble even at low temperature.
2) Electric conductivity (1M propylene carbonate solution)
IL-C15 and IL-C17 show electric conductivity equivalent to or higher than TEA-BF4.
3) Internal resistance (1M propylene carbonate solution)*
IL-C15 and IL-C17 show excellent solubility in PC compared to TEA-BF4, and are fairly soluble even at low temperature.
* Comparison taking the capacitance at 25℃ as a reference.
4) Capacitance (1M PC solution)*
In the case of 1M PC, the capacitance decreases less than that of TEA-BF4 at low temperature because IL-C15 and IL-C17 do not form crystals at low temperature.
* Comparison taking the capacitance at 25℃ as a reference.
* The stated physical properties and technical information are representative values measured by Koei Chemical. Performance and other specifications are not guaranteed.
