Material composition and structure design of lithium ion solid electrolyte
Abstract:Considering the safety of lithium battery, solid electrolyte has gradually entered people's vision. All-solid-state lithium battery system based on solid electrolyte has the advantages of high energy density, long cycle life and high safety. At present, solid electrolyte mainly includes inorganic solid electrolyte, organic solid electrolyte and compound solid electrolyte. One of the biggest obstacles is to obtain high ionic conductivity and at the same time to have appropriate mechanical properties and interface wettability, so the structure of electrolyte has become a hot topic of researchers. In this paper, three typical solid electrolyte materials are summarized and the new structure design of solid electrolyte is reviewed.
Keywords: physical chemistry of materials solid electrolyte energy storage the structure design
