Polymer electrolytes are the emerging materials for electrochemical device applications such as high energy
density batteries, fuel cells, supercapacitors, electrochromic displays, etc. Polymer electrolytes has gone through different
developmental stages, starting from dry solid polymer electrolyte (SPE) systems to plasticized, gels, rubbery to
micro/nano-composite polymer electrolytes. The main two factors that retard the applications of synthetic polymer
electrolytes are High cost and not “environmentally green”. Hence to overcome this shortcomings of synthetic polymers
biopolymers have gained enormous attention which raises the significance due to global warming and energy crisis. The
present work focuses on the characteristics of bio polymer electrolyte based on pectin and lithium nitrate. The
electrolytes were prepared using the solution casting method . A.C. impedance spectroscopy shows that the biopolymer
containing 30 wt% Pectin: 70wt%LiNO3 has highest ionic conductivity of 3.97 x 10-3 Scm-1
[1]. The analysis also proves
that the magnitude of ionic conductivity increases with an increase in temperature for which the activation energy is
minimum. The values of glass transition temperature (Tg) using differential scanning calorimetry (DSC) analysis predicts
values, which reveals that the Tg value increase with respect to the increase of LiNO3. Transference number
measurement confirms that the conducting species are Li ion. Primary lithium-ion battery has been constructed using best
conducting bio polymer electrolyte membrane, and the open circuit voltage (OCV) has been observed as 1.4 V
