Composite polymer electrolyt

The equivalent circuit of a section of this SEI is presented in Fig. 13(b). It was recently found [123, 124] that at temperatures lower than 90 °C, the grain-boundary resistance of composite polymer electrolytes and composite solid electrolytes based on Lil-A Ojis many times larger than their ionic resistance. At 30 °C / GB is several orders of magnitude larger than (the ionic resistance) and for 100 pm-thick CPE foils or Lil-A Oj pellets it reaches [125] 105-106Qcm2 (depending on CPE composition).

Composite polymer electrolytes based on PVDF (at least 35%) containing lithium salts were studied [140] by a number of techniques including Li NMR. Spin-lattice relaxation measurements were used to show that localised lithium motion is significantly impeded in some samples but not in others. [Pg.707]

Another kind of modification of PEO involves the concept of composite polymer electrolytes [33, 37-38, 138-144]. These include the use of inorganic fillers such asNASICON [138],/1-alumina [139], glassy fillers [139] y-LiA 02 [140-143]... [Pg.159]

Most of the recent papers deal with PEO and other polymers incorporated with inert fillers [30, 40-53], which also have poor mechanical properties. These films have to be hardened by chemical or physical curing, which leads to high processing costs. Recent studies reveal that only composite polymer electrolytes incorporated with inorganic filler can offer mechanically strong and safe batteries with improved electrolyte-electrode compatibility. One of the functions of the fillers is also the reduction of crystallinity of the host matrix. [Pg.937]

For the composite polymer electrolytes, the conductive carbonaceous filler must be below the electrical percolation threshold, due to the need to obtain an electronically insulating material with suitable ionic conductivity. These fillers are also used to improve the thermal stabilization and serve as mechanical reinforcement to improve the electrolyte/ electrode compatibility. CNT/P(VDF-TrFE) composites showed higher porosity and electrolyte uptake compared to the pristine polymer. CNT also contributed to increase ionic conductivity (2.6 xlO S cm , 0.1 wt.% CNT) and diminished its variations with temperature. [Pg.131]

Pitawala et al., (2007) studied the combined effect of both plasticizer and nano-ceramic filler on the thermal behavior and conductivity of (PEO)g-lithium trifiuoromethanesulphonate (LiCFjSOj or LiTf) composite polymer electrolyte. The formula (PE0)gLiCFjS03 denotes the chemical composition of the polymer-salt complex in which 9 is the molar ratio of (ethylene oxide (EOl/LiCF SOj). According to their work, addition of 15 wt% Aip lowered the and T of (PEO)gLiTf from 58 °C and °Cto 51 °C and -50 °C, respectively and the con-... [Pg.526]

In view of the many parameters involved viz. blend composition, types of plasticizer, and nano-fillers, grain size, and dispersion and so on, an in-depth study of the conductivity mechanism of the electrolyte system and an understanding of the characteristic and behavior of each additive are important in the pursuit of an appUcable PEO/PMMA composite polymer electrolyte system.

The PVA (Mw 1,25,000, Aldrich), Orthophosphoric acid (H PO ) (Ranbaxy, India) and nano particles of AEj03 (50 mn. Sigma) were used for the preparation of NCPE films. The films of Solid Polymer Electrolyte (PVA + HjPO ) and Nano Composite Polymer Electrolyte (PVA + H3PO + Al Oj) in different filler wt% ratios were prepared by solution cast technique. Grantdes of PVA were dissolved in triply distilled water and stirred magnetically for 10-12 hr to obtain a clear and homogeneous solution. A known amount of H3PO was added to it and stirred continuously until a viscous solution was obtained. A part of solution was poured into the Teflon Petri dishes to get SPE thin film and in another part of the solution, nano-sized Al Oj was added in different wt % to get NCPE thin films. The prepared thin films were rinsed with benzene/methanol to remove any volatile impurities present in it. [Pg.73]
