This technology is a supercapacitor enabled by a water-based hydrogel electrolyte, enabling operability over a wide range of temperatures.
Thin-film supercapacitors are critical electronic components for portable devices and wearable technologies due to their charging stability and portability. Many thin-film supercapacitors utilize water-based hydrogels. However, most hydrogels are not robust with regard to temperature, limiting their use in harsh conditions. There is a need for the development of water-based hydrogel electrolytes with wide temperature compatibilities in order to improve the versatility of thin-film supercapacitors.
This technology is a temperature-flexible supercapacitor enabled by a water-based hydrogel electrolyte. The electrolyte is fabricated with montmorillonite and poly(vinyl alcohol) to enable operation at temperatures ranging from -50º to 90ºC. This hydrogel composition allows for enhanced ionic conductivity and thermal stability and is also relatively cost effective ($0.29/gram). This technology has the potential to greatly increase the range of operational temperatures of hydrogel electrolytes and expand the integration of thin-film supercapacitors into functional devices.
