| 9. | The questions the researcher concerned are which system will be chosen and how to obtain the good lithium ionic conductor materials , which is the basic departure of the paper . the addition of second phase in composite can change the interface structure and the conduction mechanism , improve the matrix conductivity and other function such as the sintering , crisping and so on , so the research of composites are an interesting field of the ionic conductors . the synthesis of lithium ionic conductor is often by solid state reaction , but this method needs high temperature and leads to the volatility of lithium which not only causes the drift of the compounds but gets the no well - distributed materials
研究者所关注的问题是选择新的体系进行研究，以期得到性能更好的锂离子导体材料，这也正是本论文的基本出发点；复合离子导体中第二相的加入改善了基质的界面结构和导电机制，不仅可以提高基质材料的电导率，还可以在一定程度上改善材料的其它性能，如烧结性能、脆性和机械强度等。因此复合材料的研究是离子导体一个有广阔前景的发展方向；合成锂离子导体，特别是成分复杂的体系以传统的固相合成法为主，但这种方法需要较高的温度，容易引起锂的挥发，从而造成产物组成的偏移，而且不易得到显微结构均匀的材料。 |
