Progress in interfacial modification of inorganic solid electrolytes
All-solid-state lithium-ion battery has attracted wide attention due to its advantages of energy density and safety.As the core component of all-solid-state battery,solid-state electrolyte has a crucial impact on its performance.At present,the main solid electrolyte systems include oxides,sulfides and polymers,among which oxide solid electrolytes are relatively ideal solid electrolyte material with good performance such as energy density,stability and cycle life.However,serious interfaces contact between electrolyte and electrodes restrict the large-scale application of solid battery.Many researches focus on improving the contact of interfaces with different types of solid electrolytes.In this paper,the cutting-edge researches on the interfaces between inorgan-ic solid electrolytes and electrodes reported in recent years are reviewed,and several main interfacial modifica-tion methods are systematically summarized.The research methods of composite positive electrode,interface processing technology optimization,interface layer introduction and composite electrolyte are introduced and their application prospects are discussed.
