Development of a new plasticizer for poly(ethylene oxide
One approach to increasing the ionic conductivity of polymer electrolyte is to add plasticizers to the polymer-salt complexes. Recently, we have synthesized a new plasticizer, modified carbonate (MC3), by attaching three ethylene oxide units to the 4-position of ethylene carbonate.
New oligoether plasticizers for poly(ethylene oxide)-based
In the past decade, the development of solid polymer electrolytes (SPEs) has drawn immense attention for application in lithium-ion (Li-ion) batteries, because of their several advantages over liquid electrolytes [1,2,3,4,5].
Effect of plasticizer on the ion-conductive and dielectric
Solid polymer electrolytes consisting of CO 2 -derived poly (ethylene carbonate) (PEC), LiPF 6, and plasticizers (glycerol or 1-ethyl-3-methylimidazolium bis (trifluoromethane sulfonyl)imide,...

- Do Plasticizers improve ionic conductivity of electrolytes?
- Plasticizers, typically low-molecular-weight organic solvents like ethylene carbonate (EC), PC, and diethyl carbonate, play a crucial role in enhancing the ionic conductivity of electrolytes.
- How effective is a plasticizer?
- The effectiveness of a plasticizer depends on its inherent properties, including its dielectric constant, viscosity, and how it interacts with other components in the electrolyte system . While EC has high conductivity and is stable at high voltages, ethylene carbonate (EC) can oxidize on the surface of high-nickel cathodes.
- Can tetracyanoethylene be used as a plasticizer?
- Building upon this approach of using high-dielectric-constant additives to enhance ionic conductivity, this work focuses on incorporating tetracyanoethylene (TCE) as a plasticizer. TCE possesses a high dielectric constant (k = 148) and a unique structure with four cyano groups surrounding a double bond.
- Does TCE improve ionic transport in plasticized polymer electrolytes?
- This conductivity value surpasses those reported for other plasticized polymer electrolytes, highlighting the effectiveness of TCE as a plasticizer for enhancing ionic transport in this system . This represents a tenfold increase compared to the TCE-free electrolyte (1.13 × 10 −5 S/cm). Fig. 6.
- Is poly (ethylene oxide) a suitable material for solid-state lithium batteries?
- Poly (ethylene oxide) is a promising material for solid-state lithium batteries due to its safety, ease of processing, and compatibility with lithium. However, conventional linear PEO falls short of practical requirements due to its limited ionic conductivity, a consequence of the high crystallinity of its ethylene oxide chains.
- What is a high molecular weight polyethylene oxide (PEO)?
- High molecular weight polyethylene oxide (PEO) (MW = 8 × 10 6 g/mol), lithium bis (trifluoromethanesulfonyl)imide (LiTFSI), tetracyanoethylene (TCE) and anhydrous acetonitrile (99.8 %) were purchased from Sigma–Aldrich (St. Louis, USA). 2.2.
