A self-standing,flexible and lithium dendrite growth-suppressing composite gel polymer electrolyte membrane was designed for the use of room-temperature lithium ion *** multi-functional composite semi-interpenetrating polymer network(referred to as“Cs-IPN”)electrolyte membrane was fabricated by combining a UV-cured ethoxylated trimethylolpropane triacrylate(ETPTA)macromer with alumina nanoparticles in the presence of liquid electrolyte and thermoplastic linear poly(ethylene oxide)(PEO).The polymer electrolyte membrane exhibits a semi-interpenetrating polymer network structure and a higher room temperature ionic conductivity,which impart the electrolyte with a significant cycling(120 mAh g^(-1)after 200 cycles)and a remarkable rate(137 mAh g^(-1)at 0.1℃,130 mAh g^(-1)at 0.5℃,119 mAh g^(-1)at 1℃ and 100 mAh g^(-1)at 2℃)performance in Li/LiFePO4 *** importantly,the polymer electrolyte possesses superior ability to inhibit the growth of lithium dendrites,which makes it promising for next generation lithium ion batteries.

三维多孔固态电解质是连续型复合电解质的骨架部分。采用共沉淀法制备Li1.3Al0.3Ti1.7(PO4)3固态电解质粉体,再通过凝胶注模工艺合成了Li1.3Al0.3Ti1.7(PO4)3多孔坯体,并在不同温度下烧结,比较了烧结体的物相组成、显微形貌、收缩率、孔隙率、电导率和激活能。结果表明:在900℃以上烧结,坯体发生明显的致密化,并且产生更多的杂相,其致密度升高而电导率降低。在800℃烧结的样品,孔隙率在50%以上,具有6.94×10–5 S/cm的电导率,激活能为0.27 eV。所得多孔坯具有较高的孔隙率和电导率,使其适合作为三维有机–无机复合固态电解质的陶瓷框架。

蓝宝石因其良好的透光性和高温稳定性而成为光纤式高温压力传感器的理想结构材料。蓝宝石在高温下弹性模量的变化与其高温压力测量的准确性密切相关,因此获取高温条件下蓝宝石的弹性模量是设计和制备高温压力传感器的必要前提条件。基于高温原位XRD测试得到不同温度下蓝宝石的晶胞参数,然后利用第一性原理对蓝宝石的弹性性能进行了理论计算,得到蓝宝石高温情况下的弹性刚度矩阵和柔度矩阵。同时基于脉冲激振法,测量了室温至1200℃范围内不同取向蓝宝石样品的弹性模量,验证了理论计算结果的准确性。理论计算及实验结果均表明:随着温度的升高,蓝宝石的弹性模量减小,并且不同晶向之间存在显著差异。所获取蓝宝石的高温弹性模量数据可为相关高温压力传感器的设计提供基础数据参考。
