Protic Ionic Liquids‐Based Crosslinked Polymer Electrolytes: A New Class of Solid Electrolytes for Energy Storage Devices

Nanostructure enhanced ionic transport in fullerene reinforced solid polymer electrolytes.

Solid polymer electrolytes, such as polyethylene oxide (PEO) based systems, have the potential to replace liquid electrolytes in secondary lithium batteries with flexible, safe, and mechanically robust designs. Previously reported PEO nanocomposite electrolytes routinely use metal oxide nanoparticles that are often 5-10 nm in diameter or larger. The mechanism of those oxide particle-based polym...

Liquefied gas electrolytes for electrochemical energy storage devices.

Electrochemical capacitors and lithium-ion batteries have seen little change in their electrolyte chemistry since their commercialization, which has limited improvements in device performance. Combining superior physical and chemical properties and a high dielectric-fluidity factor, the use of electrolytes based on solvent systems that exclusively use components that are typically gaseous under...

Understanding Ionic Conductivity in Crystalline Polymer Electrolytes

Characterization of Lithium-based Solid Polymer Electrolytes

Sol-gel derived poly(oxyethylene)/siloxane hybrids doped with lithium hexafluoroantimonate, LiSbF6, have been prepared. Compositions of these novel xerogel electrolytes were identified using the conventional d-U(2000)nLiSbF6 notation, (where n is the molar ratio of oxyethylene moieties per Li + ion) and samples with n between ∞ and 2.5 were characterized by conductivity measurements, cyclic vol...

STRUCTURAL AND IONIC CONDUCTIVITYSTUDIES ONPLASTICIZED PAN-SODIUM FLUORIDE POLYMER ELECTROLYTES FOR ELECTROCHEMICAL CELL APPLICATIONS

Ion conducting gel polymer electrolytes based on poly acrylonitrle (PAN) complexed with different weight percent ratios of Sodium Fluoride (NaF) salt were prepared by using solution cast technique. Structural characterization was performed using X-ray diffraction (XRD) technique and Fourier transforms infrared (FTIR) spectroscope technique. From the X-rd results increase in amorphous phase with...
