研究了熔融碳酸盐燃料电池(MCFC)阴极材料锂铁氧化物电极的导电性能.实验结果表明在合成锂铁氧化物的过程中,使Li2CO3轻微过量,可以提高锂铁氧化物电极的导电性.在同一温度下,随着Li:Fe值的增大,锂铁氧化物电极的导电性增加.相同Li:Fe条件下,锂铁氧化物电极的导电性随着温度升高按指数规律增加.扫描电镜研究(SEM)表明,Li:Fe比值不同,制备的锂铁氧化物电极表面形貌也不同

采用微弧氧化技术在ZAlSi12合金表面制备氧化膜,研究了Li2SO4的加入对微弧氧化膜性能的影响.随着电解液中Li2SO4含量增加,试样表面氧化膜变厚且粗糙.X射线衍射分析表明,微弧氧化膜主要由Al2O3相和莫来石相组成.加入Li2SO4且经微弧氧化处理得到的试样耐腐蚀性能优于未经微弧氧化处理的试样
