This evolution has occurred, not only with respect to the number of devices, but also in their average energy storage capacity. An obvious commercial consequence has been an increased pressure to develop improved active materials for power sources and more efficient methods for battery production. In recent decades the growth of the commercial market for high performance batteries has been based on the development of both solid\u2010state and gel electrolytes. The incorporation of these electrolytes as components of various devices (advanced batteries, smart windows, displays and super\u2010capacitors) offers significant advantages relative to traditional electrolytes, including enhanced reliability and improved safety. The xerogel matrices prepared in this study are represented as U(900) and U(600) and contain 15.5 or 8.5 oxyethylene structural units (CH<jats:sub>2<\/jats:sub>CH<jats:sub>2<\/jats:sub>O) respectively. The oxyethylene chains are bonded at each end to a siliceous intersection through urea bridging links. These sol\u2010gel derived oxyethylene \/siloxane xerogels (designated as di\u2010ureasils) were doped with controlled amounts of LiAsF<jats:sub>6<\/jats:sub> or LiSbF<jats:sub>6<\/jats:sub> to prepare a range of electrolyte compositions. The compositions prepared, with 200&gt;<jats:italic>n<\/jats:italic>\u22652.5 (where the salt content is expressed as <jats:italic>n<\/jats:italic>, the molar ratio of oxyethylene moieties to Li<jats:sup>+<\/jats:sup> ions), were characterized by electrochemical and thermal techniques. Preliminary tests performed with a prototype electrochromic device (ECD) incorporating the most promising electrolyte composition, d\u2010U(900)<jats:sub>8<\/jats:sub>LiAsF<jats:sub>6<\/jats:sub> as electrolyte and WO<jats:sub>3<\/jats:sub> as cathodic electrochromic layer, are extremely encouraging.<\/jats:p>","DOI":"10.1002\/elan.201200508","type":"journal-article","created":{"date-parts":[[2013,1,22]],"date-time":"2013-01-22T16:16:04Z","timestamp":1358871364000},"page":"515-522","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Preparation and Characterization of Hybrid Oxyethylene\/Siloxane Electrolyte Systems"],"prefix":"10.1002","volume":"25","author":[{"given":"Lu\u00edsa C.","family":"Rodrigues","sequence":"first","affiliation":[]},{"given":"Maria M.","family":"Silva","sequence":"additional","affiliation":[]},{"given":"Michael J.","family":"Smith","sequence":"additional","affiliation":[]},{"given":"A.","family":"Gon\u00e7alves","sequence":"additional","affiliation":[]},{"given":"E.","family":"Fortunato","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2013,1,22]]},"reference":[{"volume-title":"Sol\u2010gel Science, The Physics and Chemistry of Sol\u2010Gel Processing","year":"1990","author":"Brinker C.
