Abstract: Provided are a battery cell testing probe mechanism, a testing apparatus, and a battery production line. The battery cell testing probe mechanism includes a connecting member and multiple test members. The connecting member is configured to connect to an external structure, and at least one test member is slidably connected to the connecting member along a first direction. Each test member corresponds to an electrode terminal of a battery cell and performs relevant data collection on the corresponding electrode terminal. When battery cells of different dimensions are tested, one or more test members can be moved relative to the connecting member along the first direction to adjust spacings between the test members, thereby meeting the testing requirements for the spacing between electrode terminals of battery cells of different dimensions and improving testing efficiency.

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.
