The development of improved performance supercapacitors, batteries, electrochromic devices, sensors, and other electrochemical devices is critical to meet the current and future needs of Naval Air Systems. The ability of electrochemical devices to operate over extreme temperature limits (-70 to +100 degrees Celsius) is essential to tactical aircraft, strike weapons, and other systems, which can encounter sub-freezing temperatures during operation. The performance of current electrochemical devices is particularly limited at low temperatures by the low conductivities and high viscosities of current organic solvent-based electrolytes. Ionic liquids offer improved safety and higher voltage windows than current electrolytes, however specific ionic liquids that permit adequate low temperature (sub-zero Celsius) operation have not been developed. During the Phase I project, Lynntech will develop low temperature ionic liquid systems with high conductivities, low viscosities, high voltage windows, and chemical and electrochemical stability with electroactive polymers. The Phase I project will optimize the electrolyte composition, determine the ionic liquids’ physical and electrochemical properties from -70 C to +100 degrees Celsius, and evaluate the electrolyte’s performance in electroactive polymer-based supercapacitors. During Phase II, Lynntech will optimize and scale up the process and demonstrate the ionic liquid’s performance in prototype devices.
