![]() ![]() The CV curve covered most of the area of the current–potential plot with no redox peaks. From linear sweep voltammetry (LSV) investigation, CS:PEO:LiClO 4 electrolyte was found to be electrochemically constant as the voltage sweep linearly up to 2.24 V. The high ion transference number and high DC conductivity emphasized the possibility of the samples for electrochemical device application. ![]() It has been verified via transference number analysis (TNM) that the transport mechanism in CS:PEO:LiClO 4 electrolyte is predominantly ionic in nature with t ion = 0.993 and t el = 0.007. The electrical equivalent circuit (EEC) model has been carried out for selected samples to clarify the common picture of the electrical properties of the system. The maximum DC conductivity was found to be 7.34 × 10 −4 S cm −1 for CS:PEO incorporated with 40 wt% of LiCLO 4 salt. The bulk resistance estimated from the impedance plots decreased with increasing salt concentration. The FTIR study revealed the complex formation between the CS:PEO and added salt through the shifting and lessening in intensity of the FTIR bands corresponding to the functional groups. The intensity of the hump observed in CS:PEO blend film decreased upon addition of LiClO 4 salt. The XRD analysis indicated that the crystalline peaks of CS vanished in CS:PEO host blend polymer. High ion transference number polymer blend electrolytes of chitosan (CS):poly (ethylene oxide) (PEO):LiClO 4 systems were synthesized using solution cast technique. ![]()
