The conducting biopolymer based on cellulose acetate with various concentration of magnesium perchlorate were prepared by standard solution cast technique. The electrical properties and electrochemical performance of as-prepared biopolymer films were investigated by electrochemical impedance technique. The maximum ionic conductivity of biopolymer electrolytes films approximately of order 10 -4 S/cm at 30 °C. The voltage stability limit of biopolymer electrolyte films was examined by linear voltammetry and cyclic voltammetry for use in energy storage device applications. The highest electrochemical window 4.5 V is achieved at 50% of Mg (ClO 4 ) 2 .
IntroductionIn this current time, a lot of energy is required to full fill the need of modern lifestyle and industry. So, the entire population of the world depends on fossil fuels. There are many disadvantages of the fossil fuels like limited resources, non-renewable, and producing massive air pollution [1,2]. All these factors motivate the research community to find an alternative resource in terms of renewability and sustainability. There are many renewable energy sources like fuel cells, wind, and solar cells [3,4]. The new and emerging science of polymer electrolytes becoming a promising candidate to store energy and replace non-renewable resources. Polymer electrolyte extensively gets used in many applications like energy storage, supercapacitor, solar
