Embodiment Construction
[0040] All-solid-state lithium batteries (ASSB) have the advantages of safety and high energy density, and have become the only way for the development of lithium batteries in the future. Among different types of electrolytes, garnet-type electrolytes are considered to be one of the most promising electrolytes for solid-state batteries due to their high ionic conductivity and good electrochemical stability towards lithium metal. However, garnet-type electrolytes face two important challenges, one is the poor contact between the electrolyte and the lithium anode, resulting in a large interfacial impedance, and the other is that the lithium dendrites penetrate the electrolyte and cause a short circuit in the battery.
