Ion conducting behaviour of silsesquioxane based materials` used in fuel-cell and rechargeable battery applications

摘要: The worldwide energy demand is expected to be double of the current consumption in the near future. This huge energy demand increases the importance of energy conversion and storage devices. A fuel cell needs an electrolyte which can be used under high temperature conditions for increasing the system efficiency. In the case of rechargeable batteries, the ion-conducting properties of the electrolyte should possess long-term sustainability. However, available electrolytes for a fuel cell can efficiently work only at temperatures below 100 °C. On the other hand, commercially used electrolytes are usually liquids and may cause serious leakage and safety problems, thus their sustainability is limited for Li-ion battery applications. Although their ionic conductivities are relatively low, solid and gel type electrolytes are safer and therefore become more favorable. More recently, compatible hybrid organic …
