Fourier Transform Infrared Spectroscopy (FTIR) indicates complexation between the polymer and the plasticizer and the polymer, the plasticizer and the salts, and the result of XRD further supports the observation.
Influence of succinonitrile plasticizer on ionic conductivity
As a plasticizer, succinonitrile (SN) has been utilized to improve the ion movement in the solid electrolytes. SN possesses a high dielectric constant (~54), low melting point (56 0 C) and plasticizing property at room temperature.
Influence of polyethylene glycol plasticizer on the
Considering the aforementioned amazing properties of PEG (which is –OH terminate and has a molecular weight of 600 g/mol), it is chosen to be used as plasticizer in the present study . In the existing scenario of lithium-based electrolyte, doping of sodium salt would help to overcome certain issues .

- Do Plasticizers improve bulk conductivity and salt diffusion coefficient of polymer electrolytes?
- As expected, the plasticizers always improved the bulk conductivity and increased the salt diffusion coefficient of polymer electrolytes at the selected temperatures. The conductivity and the salt diffusion coefficients of sample electrolytes ranked identically in the order PL10PG>PL10EC>PL10PC>PL.
- Do different plasticizers affect the properties of gel polymer electrolytes?
- Different salt concentrations (0.1 M, 0.5 M, 1 M, 2 M) were studied. The effect of different plasticizers (single and mixed) on the properties of gel polymer electrolytes were considered. The variation of conductivity versus salt concentration, thermal properties using DSC and TGA, anodic stability and FTIR spectroscopy were used in this study.
- Does plasticizer increase ionic conductivity of solid polymer electrolytes?
- The ionic conductivity of solid polymer electrolytescan be significantly in- creased by the addition of plasticizer [3,4]. The effectiveness of plasticizers in increasing the ionic conduction has led to an achievement of PEO systems with room temperature conductivities in the region of 10 S cm , but at the expense of mechanical rigidity.
- What are the advantages of PAN based lithium salt complex?
- Compared with PEO- based electrolytes, the PAN-based lithium salt com- plex has many advantages. It hashigh conductivity and good mechanical properties at room temperature. Huang Hong et al. [9-11] have made systematic studies on PAN-PC-EC-LiCU^.
- Are polymer electrolytes based on polyacrylonitrile a plasticizer?
- Polymer electrolytes based on polyacrylonitrile (PAN) withvarious plasticizers have been synthesized. Their electrical conductivities determined by AC impedance spectra are higher than 1 × 10 −3 S · cm −1 at room temperature. IR and Raman spectra gave evidence of the interactions among PAN, plasticizer and lithium salt.
- Why are polymer electrolytes used in lithium ion batteries?
- Since polymer electrolytes must function as both separator and electrolyte, a number of properties are critical for their successful use in lithium or lithium-ion batteries. From an electrochemical point of view, the electrolytes must satisfy a set of requirements.
