Abstract
Disclosed is an all-solid-state lithium battery, characterized in that an anode of the all-solid-state lithium battery comprises solid lithium metal, a solid-state electrolyte of the all-solid-state lithium battery comprises lithium lanthanum zirconium oxide, and a joint interface region between the anode and the solid-state electrolyte contains at least lithium nitride and lithium alloy.
Claims6
A manufacturing method of an all-solid-state lithium battery, characterized by the following steps:
- a first step of mixing metal nitride and lithium metal as an anode material of an anode of the all-solid-state lithium battery and heating to form a molten lithium metal nitride alloy;
- a second step of placing lithium lanthanum zirconium oxide as a solid-state electrolyte material of a solid-state electrolyte of the all-solid-state lithium battery on a surface of the molten lithium metal nitride alloy to undergo an in-situ reaction;
- and
- a third step of cooling the molten lithium metal nitride alloy so that a joint interface region between the molten lithium metal nitride alloy and the lithium lanthanum zirconium oxide contains lithium nitride and lithium alloy such that the all-solid-state lithium battery contains at least lithium nitride and lithium alloy at the joint interface region between the anode and the solid-state electrolyte.
