Characterization on conduction properties of carboxymethyl cellulose/kappa carrageenan blend-based polymer electrolyte system

Influence of Lithium Bromide on Electrical Properties in Bio-based Polymer Electrolytes

“…Upon addition of LiBr above 15 wt. %, it shows a decrease in ionic conductivity, which could be due to the neutral aggregation of the ions reassociated, thus leading to the formation of ion clusters, as reported other researchers [12], [13].…”

Study on the effect of lithium nitrate in ionic conduction properties based alginate biopolymer electrolytes

“…Based on figure 3, the Cole-Cole plot for ALNO-1, ALNO-2, ALNO-4 and ALNO-5 showed the combination of a tilted semicircle with an inclined (tilted) spike. The semicircle in impedance plot can be represented by parallel combination of bulk resistance, R b and CPE element with another CPE element in series due to tilted spike; therefore, it confirms the semiconducting behavior [28]. The values of Z r and Z i associated to electrical equivalent circuit (EEC) of tilted semicircle and spike can be expressed as:- where R is bulk resistance, k 1 -1 is the bulk geometrical capacitance of BEs, k 2 -1 is the electrical double layer capacitance at the electrode/electrolyte interface during the impedance measurement.…”

Biopolymer-Based Electrolytes for Dye-Sensitized Solar Cells: A Critical Review

“…Preceding studies of cellulose electrolytes consist of highly crystalline pure cellulose. This high crystallinity of cellulose resulted in DSSC electrolytes with low conductivity and efficiency. ,− However, this crystallinity can be reduced by the chemical modifications, plasticization, grafting, and blending with another polymer. − Various water-soluble and organosoluble cellulose derivatives have been used in DSSC electrolyte production. For example, ethyl cellulose (EC), a derivative of cellulose, was used as an organic binder for the preparation of crack-free photoanode ZnO film for DSSC .…”

“…This blending could be economical, beneficial, and environmentally conscious as these processes do not require any toxic chemical modifications and can be done in one pot. However, despite their benefits, very small studies on the blended polymer have been done until now. , So, it opens the new possibilities in the production of more conductive blend electrolytes. However, as the study is very small in this area, it cannot be firmly concluded whether natural or synthetic polymer should be used.…”
