“…The NCPEs show tremendous technological potential to develop flexible solid state polymeric batteries over the solid polymer electrolytes (SPEs). The main advantages of NCPEs are their mechanical properties, ease of fabrication of desirable shapes/sizes, and they are also important for improving the proper contact between electrode-electrolyte in polymeric batteries [1][2][3][4][5][6][7][8]. In the recent past, several PEO-based polymer electrolytes have been widely investigated because of their potential application in polymeric batteries.…”

Synthesis, characterization and polymeric battery studies of Na + ion conducting NanoComposite Polymer Electrolyte (NCPE) membranes: (1-x) [75PEO: 25NaPO 3 ]: x SiO 2 , where x = 0 -15 wt. (%), has been reported. NCPE membranes have been casted using a novel hot-press technique in place of the traditional solution cast method. The dispersal of SiO 2 in SPE host: (75PEO: 25NaPO 3 ), a conductivity enhancement of an order of magnitude achieved in NCPE film: [93 (75PEO: 25NaPO 3 ): 7 SiO 2 ]. This has been referred to as Optimum Conducting Composition (OCC). Material characterizations have been done with the help of XRD, SEM and DSC techniques. The ion transport behaviour in hot-pressed NCPEs has been discussed on the basis of experimental measurements on some basic ionic parameters viz. conductivity (σ), ionic mobility (µ), mobile ion concentration (n) and ionic transference number (t ion ). The temperature dependent conductivity studies have been done to compute the activation energy (E a ) values from the 'log σ -1/T' Arrhenius plots. The ion conducting solid state polymeric battery was fabricated and cell-potential discharge characteristics have been studied at different load conditions.

The Role of Chemistry in the Energy Challenge

Chemistry with its key targets of providing materials and processes for conversion of matter is at the center stage of the energy challenge. Most energy conversion systems work on (bio)chemical energy carriers and require for their use suitable process and material solutions. The enormous scale of their application demands optimization beyond the incremental improvement of empirical discoveries. Knowledge-based systematic approaches are mandatory to arrive at scalable and sustainable solutions. Chemistry for energy, "ENERCHEM" contributes in many ways already today to the use of fossil energy carriers. Optimization of these processes exemplified by catalysis for fuels and chemicals production or by solid-state lightning can contribute in the near future substantially to the dual challenge of energy use and climate protection being in fact two sides of the same challenge. The paper focuses on the even greater role that ENERCHEM will have to play in the era of renewable energy systems where the storage of solar energy in chemical carries and batteries is a key requirement. A multidisciplinary and diversified approach is suggested to arrive at a stable and sustainable system of energy conversion processes. The timescales for transformation of the present energy scenario will be decades and the resources will be of global economic dimensions. ENERCHEM will have to provide the reliable basis for such technologies based on deep functional understanding.

Ionic drift velocity (v d ) measurements on a hot-press synthesized nano-composite polymer electrolyte (NCPE) membrane: 95 [90PEO: 10AgNO 3 ]: 5 SiO 2 , are reported. The ionic transference number (t ion ) values were determined using dc polarization Transient Ionic Current (TIC) technique for v d measurement at different temperatures. The drift energy (E d ), involved in the thermally activated process was determined from the temperature dependent studies on ionic drift velocity using the log v d vs 1/T Arrhenius plot. At all the temperatures, the ionic drift velocity is directly proportional to the ionic mobility (µ) at a fixed value of applied dc potential.
