摘要:	摘要： A new type of highly conductive organic-inorganic hybrid polymer electrolytes has been synthesized by the reaction of poly(propylene glycol)-block-poly(ethylene glycol)-block-poly(propylene glycol) bis(2-aminopropyl ether), 2,4,6-trichloro-1,3,5-triazine and alkoxysilane precursor 3-(glycidyloxypropyl)tri-methoxysilane, followed by doping of LiClO sub(4). The super(13)C and super(29)Si solid-sate NMR results confirm the successful synthesis of the organic-inorganic hybrid structure. The solid hybrid electrolyte thus obtained exhibits a maximum ionic conductivity of 1.6 x 10 super(-4) S cm super(-1) at 30 [degrees]C, which is the highest among the organic-inorganic hybrid electrolytes. The hybrid electrolytes are electrochemically stable up to 4.2 V. The prototype electrochromic device with such a solid hybrid electrolyte demonstrates a good coloration efficiency value of 183 cm super(2) C super(-1) with a cycle life over 200 cycles. For the lithium-ion battery test, the salt free solid hybrid membrane is swelled with a LiPFe-containing electrolyte solution to reach an acceptable ionic conductivity value of 6.5 x 10 super(-3) S cm super(-1) at 30 [degrees]C. The battery cell carries an initial discharge capacity of 100 mAh g super(-1) at 0.2C-rate and a coulombic efficiency of about 95% up to 30 cycles without the sign of cell failure. The present organic-inorganic hybrid electrolytes hold promise for applications in electrochromic devices and lithium ion batteries. 出版者： Amsterdam: Elsevier 出版日期： 2014-12-10 出處： Journal of power sources, 2014-12, Vol.269, p.651-660 資源來源： Elsevier ScienceDirect Journals: Bodleian Libraries collection 版權： 2015 INIST-CNRS 識別號： ISSN: 0378-7753 識別號： DOI: 10.1016/j.jpowsour.2014.06.159 識別號： CODEN: JPSODZ
