Effect of tris(methoxy diethylene glycol) borate on ionic conductivity and electrochemical stability of ethylene carbonate-based electrolyte

A comparative study of coordination between host polymers and Li+ ions in UV-cured gel polymer electrolytes

“…5(b)-(e). This result is in good agreement with the previous studies, in which the pronounced peak at 1408 cm − 1 arises from the ion-dipole interaction between the CH 2 moieties of EC or PC and salt anions [15,16]. TEGDA and HDDA-based polymer films with EC/PC do not give the peak at 1408 cm − 1 originated from the interaction of CH 2 moiety in EC with ClO 4 \ in Fig.…”

Synthesis of borate ester-grafted carboxylated acrylonitrile butadiene rubber and its use as electron acceptor to dissolve lithium perchlorate

“…From Figs (a) and (b), one can see that there is only one binding energy peak of XNBR‐ g ‐BE (191.0 eV) for boron atom; however, there are two peaks for XNBR‐ g ‐BE–LiClO 4 (191.2 and 192.0 eV), indicating the chemical environment of boron atom in XNBR‐ g ‐BE–LiClO 4 is more complex. Previous researchers have proposed that the boron atom has an affinity to the anions of lithium salts, which is expected to reduce the interaction between cation and anion of lithium salts. Thereby, the variations of the binding energy of boron atom in XNBR‐ g ‐BE–LiClO 4 are ascribed to the interaction of boron atom with the ClO 4 − anion, which will be further proved by FTIR results later.…”

“…A number of papers have been published of studies where borate ester (BE) was incorporated as low‐molecular‐weight additive or borate species were imbedded in a polymer . The electron deficiency of borate makes the borate center an electron or anion acceptor for electron‐rich groups, which facilitates the dissociation of lithium salts in polymer matrices and improves the lithium ion transference number of polymer electrolytes by a large margin …”

Effect of Electrolytes on Electrochemical Properties of Magnesium Electrodes

“…4) A Lewis acid as an anion receptor can interact with salt anions and mitigate oxidative decomposition of anions. [7][8][9] Accordingly, the anodic limit of electrolytes is expected to be shifted to high potential by the addition of anion receptors with electron deficient atoms.…”
