“…In order to investigate the effect of inorganic nanoparticles on the lithium ionic motion, the narrowing profiles for various compositions were compared [466][467][468][471][472][473][474]476]. For all studied materials, the line narrowing occurs above T g , but the lithium mobility depends both on the concentration and the type of the nanoparticles.…”

“…The presence of these sub-micron SiO 2 particles reduce the polymer-cation interactions and suppress the crystallinity, resulting in an enhancement in the ionic conductivity. 50 Moreover, a highly conducting interface layer (grain boundary) that can assist in the enhancement of the ionic conductivity of the blended hybrid SPEs might be generated by the polymer-SiO 2 interactions. 51 Grain boundaries are sites of high defect regions that may allow rapid ion movement.…”

In this study, polyetheramine and polyetherdiamine were cross-linked separately with (3-glycidyloxypropyl) trimethoxysilane (GLYMO) and poly(ethylene glycol) diglycidyl ether (PEGDGE) and then blended in different ratios to obtain blended hybrid solid polymer electrolytes (SPEs). The blend network architecture improved the LiClO 4 salt dissociation, which led to a higher ionic conductivity of the SPEs properties, the present blend hybrid SPE has the potential to be used in lithium solid-state batteries and other electrochemical devices.

“…All the samples exhibit a relatively sharp endothermic peak at about 50 , which can be attributed to the melting of the crystalline region of PEO. The crystallinity(ɏ c ) of composite polymer electrolyte films can be obtained by comparing the heat of melting (¨H m ) with that (213.7 J/g) of 100% crystalline PEO [16] .…”

Preparation and properties of PEO/LiClO 4 /KH560-SiO 2 composite polymer electrolyte by sol-gel composite-in-situ method PAN Chun-yue( ), GAO Jin-huan( ), ZHANG Qian( ), FENG Qing( ), CHAO meng( ) Abstract: Composite polymer electrolytes based on polyethylene oxide(PEO) were prepared by using LiClO 4 as doping salt and silane-modified SiO 2 as filler. SiO 2 was formed in-situ in (PEO) 8 LiClO 4 matrix by the hydrolysis and condensation reaction of Si(OC 4 H 9 ) 4 . The crystallinity, morphology and ionic conductivity of composite polymer electrolyte films were examined by differential scanning calorimetry, scanning electron microscopy, atom force microscopy and alternating current impedance spectroscopy, respectively. Compared with the crystallinity of the unmodified SiO 2 as inert filler, that of composite polymer electrolytes is decreased. The results show that silane-modified SiO 2 particles are uniformly dispersed in (PEO) 8 LiClO 4 composite polymer electrolyte film and the addition of silane-modified SiO 2 increases the ionic conductivity of the (PEO) 8 LiClO 4 more noticeably. When the mass fraction of SiO 2 is about 10%, the conductivity of (PEO) 8 LiClO 4 -modified SiO 2 attains a maximum value of 4.8 10 í5 S·cm í1 .
