“…An increase in glass transition indicates inhibition of segmental motion of the polymer matrix. This variation is attributed to the increased coordination between Mg +2 and oxygen atoms in the host polymer 47,50 . This cross‐linkage between the cation and the oxygen atom of the polymer stiffens the polymer chains, decreasing the polymer's segmental motion 48‐50 …”

Magnesium ion conducting solid polymer electrolyte films are prepared with biodegradable methyl cellulose and Mg(NO3)2.6H2O by solution casting method. FTIR spectrum of the films confirmed the interaction between the polymer host and the metal salt. FTIR deconvolution gives a clear picture of the percentage of free ions with the salt concentration variation. Structural modification of the polymer upon salt doping are studied with XRD analysis. Glass transition temperature of the pristine film is found to increase with the concentration of the salt, which is attributed to an increase in the coordination between Mg+2 and oxygen atoms of the polymer matrix and formation of transient crosslinks. TGA analysis accounts for the thermal stability of the electrolyte films. The electrical properties of the films have been analyzed, and the values of ionic conductivities of the films were calculated. Electrolyte film with 25 wt% of the salt, which is highly amorphous, is found to have the highest room‐temperature ionic conductivity of 1.02 × 10−4 S cm−1. SEM micrographs show variation in the surface morphology of the electrolytes with the variation in the concentration of the salt. The films' electrochemical stability window and ionic transference number are calculated to find the suitability for energy storage applications.

“…Generally the Cole -Cole plot consists of two well de ned regions. The semi circle at high frequency region represented a parallel combination of capacitor (due to an immobile polarized polymer chain) and a bulk resistor (due to mobile ions in the polymer matrix), non vertical spike at low frequency region represented by a constant phase element at the electrode electrolyte interface [20]. The increase in concentration will increase the mobile charge carriers.…”

Eco-Friendly, non-toxic and biodegradable natural biopolymer electrolyte, Gellan Gum with Magnesium Chloride has been prepared by solution casting technique. The prepared biopolymer electrolyte has been characterized by XRD, FTIR, DSC and AC impedance analysis techniques. XRD study is used to analyze amorphous nature/crystalline nature of the polymer electrolyte. Complex formation between Gellan Gum and magnesium chloride salt has been studied by FTIR technique. The glass transition temperature (Tg) of the polymer electrolytes are obtained by DSC measurement. The highest ionic conductivity 2.91×10− 2 Scm− 1 has been obtained for electrolyte of 1.0 g Gellan Gum with 0.5 M.wt% MgCl2 from AC impedance analysis at room temperature. Transference number 0.97 has been obtained by Wagner’s polarization method for high conducting sample. The Mg2+ cationic transport number 0.35 has been found by Evan’s method for high conducting sample. Magnesium ion conducting battery has been constructed using the high conducting polymer electrolyte. Its open circuit voltage 2.39 V and the battery discharge characteristics are studied.

Electric vehicle owners face the problem of having limited charging station options. Individual charging stations near households can act as a viable solution to solve this problem. A forecasting model which can effectively predict the power consumption of a charging station will help charging station owners get a clear view of how much energy to produce.With this intent, this paper proposes an Internet of Things (IoT) based charging station network that acts as a platform to provide charging to electric vehicles and a model based on ARIMA whose learners are fitted to the charging station subsets with optimum parameters to increase the overall performance of sales prediction. The proposed model predicted power consumption for 7 charging stations, with average MAPE, RMSE and R2 values of 12.88%, 5.67, and 0.79 respectively.
