在快离子导体中,锂离子导体是引入瞩目的一种,因为锂的重量轻,电极电势较负,用它作固体电解质,能够做成高能量密度的电池。但直到现在还没有找到比较满意的锂离子导体,因而仍是人们探索的对象。我国的科学工作者在利用结晶化学规律探索新锂离子导体方面取得了较好的进展。例如:Na_3Zr_2Si_2,PO_(22)(Nasicon)是很好的钠离子导体,是用Si取代 Among fast ion conductors, lithium ion conductors are attracting attention because lithium is light in weight and negative in electrode potential, and can be used as a solid electrolyte to make a battery of high energy density. However, until now, no satisfactory lithium-ion conductor has been found, which is still the object of exploration. Our scientists have made good progress in exploiting the laws of crystallization chemistry to explore new lithium ion conductors. For example: Na_3Zr_2Si_2, PO_ (22) (Nasicon) is a good sodium ion conductor that is substituted with Si
