Hydrogel based electrolytes are considered as promising candidates for stretchable and flexible materials for electrolytes in supercapacitors which can be used in stretchable and wearable electronics devices. The main advantages are its high ionic conductivity, low cost, non-toxicity. However, this conventional hydrogel faces limitation in high and low temperature applications. Even in room temperature hydrogels-based devices cannot maintain its performance for long period of time. Here we propose a cellulose based organogel electrolyte as an alternative which can perform in high temperature, low temperature as well as long time stable performance in room temperature also. We selected cellulose as the polymer base for our gel which is most abundant natural polymer in earth that has property like biodegradability, biocompatibility, low cost and non-toxic. The organogel electrolyte exhibits high stretchability along with promising ionic conductivity in wide range of temperature due to its anti-drying and anti-freezing property.
