Abstract
Disclosed are a lithium metal composite electrode material for a lithium metal battery, a preparation method for the same, and an electrode, battery, battery module, battery pack and apparatus comprising the same. The lithium metal composite electrode material comprises: lithium metal particles and a lithium-containing conductive layer serving as a supporting framework, the supporting framework being filled with the lithium metal particles; wherein the lithium-containing conductive layer comprises an inorganic lithium compound and a lithium alloy. The lithium metal composite electrode material can solve the problems that, when lithium metal is used as a negative electrode, the electrolyte is easily consumed, and lithium dendrites are easily produced, deposited and dissolved to change electrode thickness, which in turn affects the cycle stability, electrical performance and structural stability of the battery, so as to achieve the purpose of improving the structural stability and cycle stability of the lithium metal electrode.
