Surface films block the charge transfer reaction between Mg anode and solid polymer electrolyte, since the mobility of Mg 2+ ions in the passivation of films becomes extremely small [45].…”

Blend polymer electrolytes were prepared with different wt% compositions of [PVA/PVP-MgCl2·6H2O] : x% using solution cast technique. Structural, morphological, vibrational, thermal, and ionic conductivity and electrochemical properties were studied on the prepared polymer films. XRD revealed the crystalline nature of the polymer electrolyte films. The morphology and the degree of roughness of the prepared films were analyzed by SEM. FTIR and Raman studies confirmed the chemical complex nature of the ligands, interlinking bond formation between the blend polymers and the dopant salt. The glass transition temperature (Tg) of polymer electrolytes was confirmed by DSC studies. Ionic conductivity measurements were carried out on the prepared films in the frequency ranging between 5000 Hz and 50000 KHz and found to be maximum (2.42 × 10−4 S/cm) for the prepared film with wt% composition 35PVA/35PVP : 30MgCl2·6H2O at room temperature. The electrochemical studies were also performed on the prepared films. The galvanostatic charge/discharge performance was carried out from 2.9 to 4.4 V for the configuration Mg+/(PVA/PVP + MgCl2·6H2O)/(I2 + C + electrolyte).

“…The past few decades have witnessed tremendous work on different polymer electrolytes. Most of the work has been carried out considering synthetic polymers such as PVdF, 19 PVP, 20,21 PEO, 22 PVA, 23 and so on. Most of the synthetic polymers are non‐biodegradable, which harms the environment.…”

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.

“…Following a reassessment of the published figures, the following issues were identified: Figure 1 in [1] with Figure 1 from [2]. In [1], the data is described as X-ray diffraction patterns of pure PVA/PVP blend polymer and with different wt% ratios of MgCl 2 ·6H 2 O, while in [2] the data is described as the X-ray diffraction pattern of PVA/PVP:GO (ii) Figure duplication in Figure 2B in [1] with Figure 2E from [3]. In [1], the data is described as the SEM images of [PVA/PVPMgCl 2 ·6H 2 O]: x% with different wt% compositions, while in [3] the data is described as SEM images of different compositions of [PVP + MgCl 2 6H 2 O]: x%.…”

“…We also asked the authors institutions to formally investigate. KL University responded to confirm the duplications but informed us that the accurate versions were published in [1], with the errors existing in the other publications; [2][3][4]. The corrections to these articles have since been published at [5][6][7], however, this article is being retracted due to concerns with the data.…”
