Borate ester plasticizer for PEO-based solid polymer electrolytes
Polyethylene glycol (PEG)-borate ester has been established as a low molecular weight plasticizer to improve the ionic conductivity of PEO-based SPE films. We have now synthesized the PEO-based star-shaped plasticizer, BR 3 (molecular weight = 896), wherein R has 6 PEO units, and incorporated it into the polymer matrix by the method of solvation.
Influence of PEG-Borate Ester as a Lewis Acid on Ionic
We produced a novel conducting polymer electrolyte and added a poly (ethylene glycol) (PEG)-borate ester as a new type plasticizer having a Lewis acidity and investigated the influence of the Lewis acidity of the PEG-borate ester to a solid polymer electrolyte containing salt.
New oligoether plasticizers for poly(ethylene oxide)-based
The borate ester–plasticized SPEs also exhibited excellent thermal and electrochemical stabilities. In this study, we present another two new oligoether-based plasticizers in which one (NOE) is terminated with nitrile groups and the other (LSA) contains lithium sulfonamide moieties.
Solid-state polymer electrolytes for high-performance lithium
Previously in the literature, solid polymer electrolytes based on PEO have been reported to exhibit p < 1 due to the cationic nature of the ion transport where Li + ions hop through coordination
- Is peg-borate a low molecular weight plasticizer?
- Polyethylene glycol (PEG)-borate ester has been established as a low molecular weight plasticizer to improve the ionic conductivity of PEO-based SPE films. We have now synthesized the PEO-based star-shaped plasticizer, BR 3 (molecular weight = 896), wherein R has 6 PEO units, and incorporated it into the polymer matrix by the method of solvation.
- What is peg-borate ester (B-peg)?
- Poly (ethylene glycol) (PEG)-borate ester (B-PEG) has been employed as a plasticizer in PEO or PAN based polymer electrolytes to enhance both the Li+ transference number and the C-rate performance of the according LMBs in many previous studies [ , , , , , , , , , , , , , , , ].
- Are solid polymer electrolytes better than inorganic solid electrolyte?
- Compared with inorganic solid electrolyte, solid polymer electrolytes (SPEs) have many attractive properties, such as light weight, easy processing and excellent ductility, etc. [, , , ] However, high interfacial impedance and poor C-rate performance of lithium ion batteries with SPE largely inhibit its widely application.
- What is the synergistic effect of Si-peg in polymer electrolyte?
- Hence, exerting the synergistic effect of Si-PEG and B-PEG in polymer electrolyte is an effective strategy to improve the flexibility of molecule chains and get both high ionic conductivity and t L i + of polymer electrolyte.
