Ambient and Subambient Temperature Polymeric Electrolytes. Synthesis and Physical

摘要

The results obtained in several laboratories have clearly demonstrated that the lithium electrode undergoes serious passivation when in contact with highly conducting gel electrolytes. This results mainly from the high reactivity of lithium toward the organic solvents present in gels. In order to decrease the interfacial resistance, electrolytes are sought for, which would be less aggressive towards lithium, or systems are used, in which lithium metal electrode is replaced by lithium intercalated materials. A majority of works in this field are canted out by the trial-and-error method since phenomena at electrode interfaces are still not well investigated. Within this work we are studying the possibility of elaborating highly conducting systems not containing organic solvents, as well as the passivation reactions of lithium electrode and intercalating electrodes in gel systems.
