Abstract: | Increasing demand of energy has led to the current wave of research for renewable newlineenergy sources. Materials aspect of electrochemical devices can be divided in two branches newline(i) electrolyte materials and (ii) electrode materials. Present work deals with electrolytes. newlineLiquid electrolytes are the best, from conductivity point of view, but the mechanical newlineproblems are associated with them, which forced the scientific community to search for newlinealternatives. Polymer electrolytes, having physique of solids and conductivity comparable to newlineliquids, came as an excellent class of electrolytes. Armand was the first to recognize the newlinetechnical importance of this class of materials. Since then considerable efforts are newlinecontinuously being made to improve these materials, and success is achieved in newlinecommercialization of polymer based energy devices. Polymer electrolytes, presently used in newlinecommercial devices, have small liquid component which are associated with serious newlineproblems like volatility, explosion etc. Hence for fabrication of devices along with good newlineelectrochemical properties, many other properties such as non-volatility, non- inflammability, newlineelectrode electrolyte contact etc are also very important. To address the above mentioned newlinesafety concern and to get flexibility in cell design, considerable attention has been given to newlinedevelop electrolytes having desired features. In this reference, synthesized polymer newlineelectrolytes have a good scope, because they have flexibility to combine good conductivity, newlinemechanical and other properties by modifying the synthesis process/crosslinking/ newlinegelatinization etc. Hence lab synthesized host matrix are becoming popular to explore the newlinepossibilities of new polymer-salt complexes. In same relevance, Ohno et al. reported that newlinepolymers having both +ve and ve charges on same molecular unit may play an important newlinerole in electrolyte preparation. In these materials constituent charges on matrix do not move under potential gradient hence better targeted ion transference number is expected. |
