“…It can form coordinate bonds with lithium salts, resulting in fast ion transport in solid polymer electrolytes. [ 200 ] Among various lithium salts, LiClO 4 has been often incorporated into PMMA such as 49% PMMA‐grafted natural rubber (MG49)/LiClO 4 , [ 191,201 ] PMMA/LiClO 4 /dimethylacetamide, [ 202 ] and PMMA/LiClO 4 /propylene carbonate. [ 192,203 ] Rajendran et al [ 190 ] successfully fabricated a polymer electrolyte membrane comprising PMMA, PVDF, and LiClO 4 .…”

Lithium–sulfur (Li–S) batteries are one of the most promising next‐generation energy storage systems due to their ultrahigh theoretical specific capacity. However, their practical applications are seriously hindered by some inevitable disadvantages such as the insulative nature of sulfur and Li2S, volume expansion of the cathode, the shuttle effect of polysulfides, and the growth of lithium dendrites on the anode. Of these, the polysulfide shuttle effect is one of the most critical issues causing the irreversible loss of active materials and rapid capacity degradation of batteries. Herein, modified separators with functional coatings inhibiting the migration of polysulfides are enumerated based on three effects toward polysulfides: the adsorption effect, separation effect, and catalytic effect. To solve the shuttle effect problem, researchers have replaced liquid electrolytes with solid‐state electrolytes. In this review, solid‐state electrolytes for lithium–sulfur batteries are grouped into three categories: inorganic solid electrolytes, solid polymer electrolytes, and composite solid electrolytes. Challenges and perspectives regarding the development of an optimized strategy to inhibit the polysulfide shuttle for enhancing cycle stability in lithium–sulfur batteries are also proposed.

“…Besides its amorphous structure can help with the dissociation of lithium salts. However, the low mechanical strength and low Li + transferring numbers (<0.5) PMMA delivers puzzles investigators to some degree [22,82]. To solve these problems, PMMA-derived copolymers and blends have been newly developed as GPEs for Li-S coins.…”

“…This infers that the total ionic conductivity is mainly due to the flow of ions and electron contribution to total conductivity is negligible, which is desirable for the solid state ionic conductor (Table 3). Also, the transference number clos to unity eliminates the issue of concentration polarization during cell operation [48]. The ionic and electronic conductivity are also calculated through suitable equations 3 as given in in table 3.…”

Abstract:Herein, we present preparation of solid polymer electrolyte (SPE) comprising of PEO, NaPF6 and varying fraction of Succinonitrile (SN) by standard solution cast technique. The morphological features and structural properties were studied by the FESEM, XRD, respectively. FTIR was performed to study the interactions between polymer host, salt, and SN. Impedance spectroscopy, Transference number measurements, LSV and CV were used to examine the electrochemical properties. The complex permittivity/conductivity & modulus were studied to understand the dielectric properties by evaluating the dielectric strength, relaxation time, hopping frequency and dc conductivity. Based on the experimental results an interaction mechanism is presented.
