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
研究者所關注的問題是選擇新的體系進行研究，以期得到性能更好的鋰離子導體材料，這也正是本論文的基本出發點；復合離子導體中第二相的加入改善了基質的界面結構和導電機制，不僅可以提高基質材料的電導率，還可以在一定程度上改善材料的其它性能，如燒結性能、脆性和機械強度等。因此復合材料的研究是離子導體一個有廣闊前景的發展方向；合成鋰離子導體，特別是成分復雜的體系以傳統的固相合成法為主，但這種方法需要較高的溫度，容易引起鋰的揮發，從而造成產物組成的偏移，而且不易得到顯微結構均勻的材料。 -
