Li ion conduction on plasticizer-added PVAc-based hybrid
The ionic conductivity of plasticizer-added polymer electrolytes is calculated from σ = L / R b A, where σ is the ionic conductivity, L is the thickness of the polymer electrolyte film, and A is the surface area of the film. Table 1 shows the conductivity values of the complexes in the temperature range of 302–363 K.
Novel Li-ion conduction on poly(vinyl acetate)-based hybrid
From Table 1, it is concluded that the electrolyte containing EC, PC plasticizers exhibits maximum ionic conductivity of the order of 5.033 × 10 4 S cm 1 which is mainly due to the specific properties of the plasticizers such as higher dielectric constant and lower viscosity.
Li ion conduction on plasticizer-added PVAc-based hybrid
The structural and the complex formation have been confirmed by X-ray diffraction spectroscopic analysis. Thermal stability of the different plasticizer-added electrolyte films has been analyzed by means of thermogravimetric analysis. Ionic conductivity of the electrolyte samples has been found as a function of temperature and the plasticizers.

- Can poly(vinyl acetate) based polymer blend electrolytes be synthesized by solvent casting?
- The present work describes the Li-ion conduction in Poly (vinyl acetate) (PVAc) based polymer blend electrolytes have been synthesized by solvent casting technique for lithium battery applications. Characterization by XRD, SEM, AFM, FTIR, TG/DTA and photoluminescence was performed for synthesized polymer electrolytes.
- What type of electrolytes are used in ionic conductivity analysis?
- Solution type electrolytes consisting of polymers such as poly (ethylene oxide) PEO and poly (propylene oxide) PPO or their blend complexed with suitable salts (LiClO 4, LiCF 3 SO 3, etc.) were prepared and reported . It is noted that the salt content is effectively affecting the ionic conductivity.
- What is the maximum ionic conductivity of a PVAC-PVDF-co-HFP complex system?
- The maximum ionic conductivity of (0.5269 × 10 −4 Scm −1) at 303 K was observed for PVAc:PVdF-co-HFP ( (25/75) wt%):LiClO 4 (8 wt%) complex system. Finally, electroscope images described the presence pores. The emission peaks observed from the photoluminescence spectra were in line with the conductivity results.
- Are solid polymer electrolytes suitable for lithium ion batteries?
- Recently, solid polymer electrolytes are of interest for use in solid state lithium-based batteries because they provide advantages over conventional lithium ion batteries, including higher safety and added design flexibility for cells of unique shape and size , , , .
- How does LiClO 4 affect ionic and polymer segmental mobility?
- For a higher concentration of LiClO 4, the build-up of charge carriers is offset by the retarding effect of ion aggregates such as ion pairs and ion triplet formation, which cause constraints in ionic and polymer segmental mobility.
