Development on Solid Polymer Electrolytes for Electrochemical Devices

“…The authors have concluded that the electron-beam treatment is an effective approach as compared to gamma-ray radiation in making the SPE more conducting due to reduction in crystallinity. Recent work illustrated contradictory results, wherein no effect was observed on the conductivity upon neutron irradiation at varied dosages (15 to 47 kGy) on PVDF-LiBOB SPEs prepared via solution-casting route [82]. Ambient conductivity was the highest at 1.27 × 10 −5 S cm −1 for the non-irradiated SPE as compared to similar electrolyte after exposed to neutron radiation with lowest value at 4.30 × 10 −7 S cm −1 for SPE subjected to 47 kGy dose [82].…”

This was attributed to decrement in µ and D, as well as higher degree of crystallinity.…”

“…This was attributed to decrement in µ and D, as well as higher degree of crystallinity. The authors have deduced that an improvement in mechanical integrity in the electrolyte has occurred after being irradiated with a neutron [82]. Sinha et al [83] have observed that there was a slight decrement in conductivity at ambient temperature for the solution-cast-prepared SPE based on PEO with ammonium perchlorate (NH 4 ClO 4 ) salt after being irradiated with gamma rays, followed by minor conductivity increment at 50 • C. In the following sections, additional ingredients such as secondary polymer, plasticizers, fillers and other additives that have been integrated into various SPEs are discussed.…”
