摘要
无机固体电解质又称快离子导体,具有高的离子电导率、低的电子电导率和较小的活化能,还具有机械强度高,承受温度范围宽,化学稳定性好,作为电解质的锂离子电池具有超长的储存寿命等优点,受到人们的重视。其中,玻璃态硫化物快锂离子导体具有高达10-3s/cm的室温离子电导率而备受青睐。综述了玻璃态硫化物快锂离子导体的研究进展,并对今后的研究方向进行了展望。
Inorganic solid state electrolytes with high ionic conductivity, low electronic conductivity and activation energy, called super ionic conductors, are attracting excessive attentions for their advantages such as high strength , good thermal endurance, stable electrochemical characteristics and superior charge-discharge mechanical property. Recently, glassy sulfides lithium super ionic conductor have been investigated extensively for their high ionic conductivity, up to 10^-3 s/cm at room temperature. The research progress of lithium super ionic conductor sulfide is summarized and the fature trends are presented as well. glasses
