Lithium/garnet-based solid electrolyte interface with low interface impedance and preparation method thereof
一种低界面阻抗的锂/石榴石基固态电解质界面及其制备方法
Abstracts:
The invention relates to a lithium/garnet-based solid electrolyte interface with low interface impedance and a preparation method thereof, in particular to a lithium metal battery and a preparation method thereof. The lithium metal battery includes: a substrate, a positive electrode supported on the substrate, a garnet-based solid electrolyte disposed on the positive electrode, and a lithium negative electrode disposed on the garnet-based solid electrolyte. One type of color-changing layer is disposed on the lithium Between the negative electrode and the garnet-based solid electrolyte. This type of color-changing layer includes: a first part and a second part. The first part is a lithium-containing compound, and the second part is a garnet component. A method for preparing a lithium metal battery includes: stacking a garnet source and at least one lithium source together to obtain a laminate; heating the laminate at a temperature of ≥300°C for 1 second to 20 minutes Time to form the color-changing layer, so that the color-changing layer is disposed at the interface of the garnet-based solid electrolyte and the lithium negative electrode.
