The technological developments demand high-temperature stable energy storage devices for the application like Electric vehicles, Oli-Gas industries, Military and Aerospace. The safety and high-temperature durability is still a big challenge because of electrolyte degradation and separator instability at higher temperatures. To address this issue, we report synthesis of electrolyte, which can provide reliable performance and durability in harsh conditions. Tailor made ionogel electrolyte structure was prepared by synthesizing double network gel from compatible polymers and by combining it with room temperature ionic liquid. Flexible supercapacitors (f-SC) with graphitic carbon electrode and prepared ionogel show stable supercapacitor performance at 150oC with good cyclic stability. The f-SCs showed extreme long-term stability with very little/no compromise with performance under high-temperature operation and a flexibility test in both static and dynamic modes at elevated temperatures. |
