“…35 The asymmetry absorption bands at 2995 cm 21 and at 2952 cm 21 are attributed to the CH 3 À ÀO and aÀ ÀCH 3 of the PMMA respectively. The absorption bands seen at 1481 and 1388 cm 21 are characteristic of the aÀ ÀCH 3 asymmetry scissoring and symmetry scissoring respectively. A scissoring band of the CH 3 À ÀO group is located at 1448 cm 21 .…”

“…FTIR spectroscopic studies were carried out using a Perkin-Elmer GX2000 FTIR spectrophotometer at room temperature in the frequency range 4000-500 cm 21 . The ionic conductivities were measured using a ZL5-LCR impedance analyzer over the temperature range 25 2808C controlled by circulating water bath with a temperature controlled under an oscillation potential of 50 mV from 100 kHz to 1 Hz (Shanghai, China).…”

Poly(methylmethacrylate)(PMMA)/oxymethylene-linked polyoxyethylene multi-block polymer(Om-POE n , where n represents number of unit À ÀCH 2 CH 2 OÀ À) blend based composite electrolyte films containing different lithium salt concentration and nanofillers' content are prepared using solvent evaporation technique. The interaction of polymersalt complex has been confirmed using FTIR spectral studies. The figuration of CPE was studied by XRD. Ionic conductivity and thermal behavior of the CPEs were studied with various salt concentrations, temperature, and nanofillers' content. The surface structure of the CPE is also investigated using scanning electron microscopy. The high room temperature ionic conductivity, transmittivity in the visible region, and thermal stability make these CPEs potential candidates as solid-like electrolytes for electrochemical devices.

Blended polymer electrolytes based on poly(ethylene oxide) (PEO) and boroxine ring polymer (BP) solvated with lithium triflate were formulated and evaluated. Compared to PEO-salt polymer electrolyte, ionic conductivities of blended polymer electrolytes were two orders of magnitude higher in a low-temperature range; as well, lithium transference numbers were increased to ϳ 0.4. These were due to the increased mobility and anion trapping of boroxine rings. BP also exhibited the stabilizing effect on lithium-polymer electrolyte interface, and a reduced interfacial resistance between lithium metal and the polymer electrolyte was found with increasing of BP content. Polymer electrolytes based on PEO and BP are suitable for use in lithium secondary battery.

A series of polymers with oligo(ethylene oxide) (OEO) side chains containing aromatic moieties were synthesized through ring‐opening metathesis polymerization (ROMP). Their potential usage as electrolytes in secondary lithium batteries was investigated. These polymers, while blended with LiClO4, formed amorphous phase with discrete glass transition temperatures (Tg). The interaction between ethylene oxide and lithium ions were analyzed by differential scanning calorimetry and solid‐state nuclear magnetic resonance spectroscopy. Evidence showed that the OEO side chains coordinated to lithium ions effectively comparable to that which happens in regular poly(ethylene oxide) electrolytes.
