自从七十年代Steele和Armand等提出用嵌入材料作为电池的活性物质以来,新型的高能锂电池有了很大的发展.这类电池反应的特点是伴随电子转移的同时还有锂离子进入阴极主体晶格中,故称为嵌入反应.然而,从研究嵌入反应的方法来看,除了电位扫描等经典的电化学技术以外,用的是X射线衍射、X射线光电子能谱等非现场的表面测试技术,分析放电后阴极中有锂存在,证明这类反应机理是锂离子的嵌入反应.迄今为止,尚未见到在放电过程中现场检测锂离子嵌入的方法的报导.鉴于嵌入反应电池的阴极材料大多数是金
Since the 1970s Steele and Armand proposed the use of embedded materials as the battery active material, the new high-energy lithium battery has been greatly developed.Characteristic of this type of battery is accompanied by electron transfer along with lithium ions into the cathode body Lattice, so called embedded reaction.However, from the study of embedded reaction method, in addition to the potential electrochemical scanning other than the classical electrochemical techniques, using X-ray diffraction, X-ray photoelectron spectroscopy and other off-site surface testing Technology to analyze the presence of lithium in the cathodes after discharge shows that this kind of reaction mechanism is the intercalation reaction of lithium ions.To date, there is no report about the method of on-site detection of lithium ion intercalation during discharge.With the fact that the cathode material embedded in the reaction cell Most are gold
