Effect of LiAlO2 nanoparticle filler concentration on the electrical properties of PEO–LiClO4 composite

Polymer composites and blends for battery separators: State of the art, challenges and future trends

“…The main effect of the addition of LiAlO 2 into a PEO matrix [171] is the increase of the polymer amorphous phase, leading to increased RT ionic conductivity by 100 times (9.76 Â 10 À5 S/cm) with respect to the pristine polymer. These composites also show enhanced stability in the interface with Li electrodes [75] and reinforced mechanical properties [75,172].…”

High‐performance solid PEO/PPC/LLTO‐nanowires polymer composite electrolyte for solid‐state lithium battery

“…In recent years, several SPEs with high ionic conducting property based on poly (ethylene oxide) (PEO), poly (methyl methacrylate) (PMMA), polyacrylonitrile (PAN), and poly (vinylidene fluoridehexaflour propylene) (PVDF‐HFP) had been reported . Especially, because of their (the ether chains) strong interactions with lithium ions and the unique ionic conducting characteristics, much attention had been devoted to SPE based on PEO . However, the properties of PEO‐based SPEs studied at present were far from being able to meet the applicable requirement.…”

“…[10][11][12][13][14][15] Especially, because of their (the ether chains) strong interactions with lithium ions and the unique ionic conducting characteristics, much attention had been devoted to SPE based on PEO. [16][17][18] However, the properties of PEO-based SPEs studied at present were far from being able to meet the applicable requirement. For example, PEO-based SPEs suffered from low ionic conductivity and small ion transference number (ITN) at ambient temperature or even at lower temperature, narrow electrochemical stability window, poor thermal stability, and the generation of high resistance layers at the interface of SPEs and lithium electrode.…”

Evaluating the electrochemical properties of PEO‐based nanofibrous electrolytes incorporated with TiO2 nanofiller applicable in lithium‐ion batteries

“…Notably, the aforementioned nanoparticles are able to compensate poor mechanical strength created by the increase of amorphous phases . Al 2 O 3 , TiO 2 , MgO, ZnO, SiO 2 , and ϒ‐LiAlO 2 are common ceramic nanofillers which have been reported in many literatures for ionic conduction improvement . Liu et al indicated that the ion conductivity of PEO/LiBF 4 polymer electrolyte could be enhanced an order of magnitude by the addition of TiO 2 filler to the host polymer matrix.…”
