摘要
在锂离子蓄电池研究中，为寻找合适的电液，进行了有机混合电液的研究。关于这方面的资料国内外报道很少，尤其分解电位的数据报道更少，我们根据工作的需要开展了这方面工作。通过对各种溶质、溶剂不同配比组成的各种有机混合电液进行粘度、导电率、电化学窗口的测定及ＬｉｘＣｏＯ２在部分电液中溶解分析，并进行了电性能比较，结果表明：相同溶质不同混合溶剂组成的电液，它们的粘度、电导率及电化学窗口不同；不同溶质相同的混合溶剂组成的电液，它们的粘度、电导率及电化学窗口也不同；
We have done the research of organic mixed electrolyte to find appropriate electrolytes in the filed of lithium battery. There is little information on this subject in domestic or overseas report especially, on the data of decomposed potential, and most of them are the features of organic electrolytes with single composition. So we should obtain the data through our experiments.Having measured the viscosity, specific conductivity and electrochemical window of organic electrolytes with different compositions of various solutes and solvents, and analyzed the solubility of Li xCoO 2 in above electrolytes, the comparison of performance for various electrolytes are showed as follows:Organic electrolytes with different solvents and same solutes have different features of the viscosity, specific comductivity and electrochemical window.Organic electrolytes with different solutes and same solvents have different features of the viscosity, specific conductivity and electrochemical window.Different electrolytes have various influences on chage dischage characteristics of Li xCoO 2.
