聚环氧乙烷(PEO)聚合物电解质有望应用于全固态锂金属电池.然而,目前还没有提出有效的方法制备全固态PEO电解质,以克服其在室温下无法使用的局限性.在本研究中,我们基于聚合物C-H键功能化策略,通过在聚合物链上直接共价连接具有锂配位活性的丁二腈官能团,设计出了一种高离子导电性PEO电解质.该官能团有效增强了PEO链的无序性和流动性,同时也作为链间快速离子传导的活性位点,从而实现了离子周围自由体积和迁移行为的双重优化.得益于官能团对离子输运的精准调节,新型电解质表现出更强的离子传导性(离子电导率提升100倍)、更高的转移数(tLi+=0.51)和更宽的电化学窗口(>0.47 V).特别是功能化的PEO300k电解质具有超高室温离子电导率(25℃时为1.01×10^(-4)S cm^(-1))并且能够在室温下稳定工作,该研究为开发具有实际应用价值的聚合物电解质提供了新的途径.

In recent years, interest in hydrogen as a fuel has sharply increased in the field of alternative and green energy due to its high energy capability and zero-emission behaviour. As a result, research in the development of new highly efficient methods for producing high-purity hydrogen is relevant. This paper presents, for the first time, the test results of an electrochemical cell with a proton-conducting La_(0.9)Sr_(0.1)ScO_(3-δ) electrolyte and symmetrical Sr_(1.95)Fe_(1.4)Ni_(0.1)Mo_(0.5)O_(6-δ)+ La_(0.9)Sr_(0.1)Sc_(0.9)Co_(0.1)O_(3-δ) electrodes as a hybrid setup for electricity generation in proton ceramic fuel cell mode, for hydrogen separation from H_(2)+ Ar mixture and the production of high-purity hydrogen from methane with simultaneous CO_(2) *** was found that this electrochemical cell generates high flow rates of hydrogen during its separation through a proton-conducting membrane from H_(2)+ Ar mixture, about 500 cm^(3)h^(-1)cm^(-2)at a current density of 0.6 A cm^(-2)as well as about 370 cm^(3) h^(-1)cm^(-2)at a current density of 0.5 A cm^(-2) from CH_(4)+ CO_(2) mixture at 800 ℃ which shows that these cells are promising for hydrogen production.

The concerns over energy crisis and climate change caused by the excessive consumption of fossil fuels and the associated emission of greenhouse gases, have driven many countries to develop policies for an energy transition into zero-carbon energy sources, essentially aiming at decarbonizing their energy systems. Among various renewable sources, hydrogen has been hailed as an ideal alternative to provide secure, cost-effective, and non-polluting energy. In recent years, there has been noteworthy progress in hydrogen electrochemical conversion and utilization techniques and devices, including water electrolyzers, proton-exchange membrane fuel cells (PEMFCs), solid oxide fuel cells (SOFCs), etc. Each of these technologies has yielded a series of encouraging advances. To showcase these recent advances, Frontiers in Energy is launching a special issue titled “electrochemical conversion and utilization of hydrogen energy”.

Novel Nano-composites SDC–LiNaSO_4 as Functional Layer for ITSOFC

引用

Nano-Micro Letters 2015年第3期7卷 268-275页

作者： Weiming Lv Ze Tong Yi-Mei Yin Jiewei Yin Zi-Feng Ma Shanghai electrochemical Energy devices Research Center School of Chemistry and Chemical Engineering Shanghai Jiao Tong University Shanghai Research and Development Center for Polymer Materials

As an ionic conductive functional layer of intermediate temperature solid oxide fuel cells(ITSOFC), samarium-doped ceria(SDC)–Li Na SO4nano-composites were synthesized by a sol–gel method and their properties were investigated. It was found that the content of Li Na SO4 strongly affected the crystal phase, defect concentration, and conductivity of the composites. When the content of Li Na SO4 was 20 wt%, the highest conductivity of the composite was found to be, respectively, 0.22, 0.26, and 0.35 S cm-1at temperatures of 550, 600, and 700 °C, which are much higher than those of SDC. The peak power density of the single cell using this composite as an interlayer was improved to, respectively, 0.23, 0.39, and 0.88 W cm-2at 500, 600, and 700 °C comparing with that of the SDC-based cell. Further, the SDC–Li Na SO4(20 wt%)-based cell also displayed better thermal stability according to the performance measurements at 560 °C for 50 h. These results reveal that SDC–Li Na SO4 composite may be a potential good candidate as interlayer for ITSOFC due to its high ionic conductivity and thermal stability.
