Lithium-7 NMR and ionic conductivity studies of gel electrolytes based on poly(methylmethacrylate)

Novel Li-ion conduction on poly(vinyl acetate)-based hybrid polymer electrolytes with double plasticizers

“…However, they showed poor ionic conductivity of the order of 10 -7 S cm -1 at ambient temperature. Further, efforts have been made to enhance the ionic conductivity of the polymer matrix with the help of various processes such as blending of two polymers [4], addition of plasticizers with the polymer electrolytes to form the plasticized polymer electrolyte [5][6][7][8], addition of fillers to make the composite polymer electrolytes [9][10][11][12], etc. Among these approaches, plasticized polymer electrolytes have been proved to be promising for the electrolytes of the lithium batteries owing to their high ionic conductivity [13].…”

Influence of Temperature on Supercapacitor Components

“…Various polymer electrolyte systems have been prepared for lithium ion batteries using different polymer matrices such as polyethylene oxide (PEO) [85][86][87], polymethyl methacrylate (PMMA) [88], polyacrylonitrile (PAN) [89], polyvinylidene fluoride (PVdF) [90], and polyvinylidene fluoride-hexafluoro propylene (PVDF-HFP) [91]. These polymer matrices may also be applied in supercapacitor electrolytes for new designs of polymer electrolytes with good electrochemical and thermal performance.…”

Infrared and conductivity studies on blends of PMMA/PEO based polymer electrolytes

“…This work inspired intense research and development on the synthesis of new polymer electrolytes, physical studies of their structure, ion transport, modeling of ion transport mechanisms and the physical and chemical properties at the electrode-electrolyte interface. Nowadays, several types of polymer electrolytes are developed and characterized, especially those based on polyethylene oxide (PEO) [7][8], poly-(acrylonirile) (PAN) [9][10][11][12] poly(methylmethacrylate) (PMMA) [13][14][15], poly(vinyl chloride) [16][17][18] and poly(vinylidene fluoride) (PVDF) [19][20]. These polymer electrolytes exhibit conductivities in the range of 10 -8 to 104 Scm ~ at temperatures between 40 to 80 ~ Many investigations have been focused on the enhancement of the room-temperature conductivity, using various appro aches such as preparing blends, copol ymers, combbranch polymers and cross-linked networks.…”
