“…PEO based electrolytes represent the archetype of this material class ever since the pioneering work of Wright et al [8,9] and Armand et al [10,11] who observed that Li salts can be dissolved in polyethylene oxide and exhibit ionic conductivity. A rather important characteristic of the PEO based polymer electrolytes is their strong tendency towards crystallisation and the concomitant formation of a mixture of different phases.…”

Ionic TransportResearch on solid ionic conductors for use as electrolytes in all solid state batteries still constitutes a rather vivid branch of today's materials science. Despite enormous efforts, neither the development of a solid electrolyte fulfilling the key requirements such as mechanical stability and high ionic conductivity at ambient temperature has been successful nor has an extended understanding of the local Li coordination motifs in the often amorphous systems been obtained. In this contribution, recent progress both in the development of novel solid state electrolytes with high ionic conductivity and mechanical stability and in the characterization of the local Li coordination motifs in these electrolytes from our laboratory is presented. The work was performed as a project within the framework of the Collaborative Research Centre SFB 458 "Ionic Motion in Materials with Disordered Structures -From Elementary Steps to Macroscopic Transport". Results will be given for polymer electrolytes based on polyethylene oxide (PEO), polyphosphazene (PPZ) and polyacrylonitrile (PAN) with various Li salts, nano-composites of these polymer electrolytes and Al 2 O 3 as a ceramic filler, novel inorganic/organic hybrid electrolytes, in which a mixture of an ionic liquid and Li salt is confined within the pore system of a SiO 2 glass, and a crystalline electrolyte, Li 5 La 3 Nb 2 O 12 . Employing a range of advanced solid state NMR methodologies including dipolar based NMR techniques and pulsed field gradient (PFG) NMR and impedance spectroscopy we were able to obtain a detailed knowledge about the local Li cation coordination motifs and the mechanism of Li transport in these electrolytes. Especially the hybrid electrolytes and the salt rich PAN based polymer electrolytes were identified as rather promising materials which combine a high ionic conductivity and mechanical stability.

“…The idea of preparation of polymer electrolytes was first proposed by Wright andFenton et.al in 1973 [wright et al, 1973] but their technological significances are fulfilled and appreciated by Armand et.al few years later [Armand et al, 1998]. Poly (ethylene oxide) was the first solvating polymer to be proposed and studied in solid polymer electrolyte (SPE) Li-rechargeable batteries.…”

“…Iontophoretic devices are in 3 parts -a power source providing up to 4mA at constant current (corresponding to a 8 cm 2 patch delivering the maximum desirable current density of 0.5 mA/cm 2 ) which, in the future, could well be a polymer electrolyte battery -a drug electrode which provides the reservoir of active ingredient -and an "indifferent" (or ground or dispersive) electrode [43,44]. The reservoir can be made from materials analogous to the polymer electrolytes originally developed by Michel Armand [45][46][47]. Sensor control of drug flux is very desirable and an impedance-based implantable microelectromechanical system (MEMS) device has recently been reported [48].…”
