我们目前的电解质添加剂丙烯腈（AAN），它允许使用碳酸丙烯酯（PC）为基础的电解质与石墨阳极的结果。本报告将集中在基本的电化学性能和XPS结果的薄膜中形成的AAN的存在。关于AAN的现场调查的进一步数据在本会议的另一篇论文中提出。这两个报告的组合给出了强有力的证据，即固体电解质界面（SEI）形成的初始步骤是阴极的，即通过还原诱导的乙烯基的电聚合。它的结论是，这种电聚合也可能是其他乙烯基化合物，如碳酸亚乙烯酯（VC），醋酸亚乙烯酯等的主要还原机制。
We present results on the electrolyte additive acrylic acid nitrile (AAN), which allows the use of propylene carbonate (PC)-based electrolytes together with graphitic anodes. This report will focus on the basic electrochemical properties and on XPS results of the films formed in the presence of AAN. Further data on in situ investigations of AAN is presented in another paper of this proceedings. The combination of both reports gives strong evidence, that the initiative step for solid electrolyte interphase (SEI) formation is a cathodic, i.e. by reduction induced electro-polymerisation of the vinyl-group. It is concluded that this electro-polymerisation may also be a main reduction mechanism of other vinyl compounds such as vinylene carbonate (VC), vinylene acetate and others.
