Therefore, it is reasonable to speculate that in the lithium-deficient scenario, the rapid consumption of active lithium metal in the negative electrode leads to the delithiation of Li 2 O to supplement lithium ions and maintain battery cycling 66.
This results in a lithium metal negative electrode, used in both laboratory or industry scenarios, typically with a thickness of several tens to even hundreds of micrometers, which not only leads to the wastage of this costly metal resource but also significantly compromises the energy density of SSLMBs 10.
Lithium (Li) metal is widely recognized as a highly promising negative electrode material for next-generation high-energy-density rechargeable batteries due to its exceptional specific capacity (3860 mAh g −1), low electrochemical potential (−3.04 V vs. standard hydrogen electrode), and low density (0.534 g cm −3).
Consequently, the controllable construction of thin lithium metal negative electrodes would be critical for improving battery energy density and safety and, more importantly, for fully and accurately exploring battery operation/failure mechanisms.
In the top-view SEM images, the surfaces of these thin lithium layers are smooth and uniform (Supplementary Fig. S12c, d). It demonstrates the enhanced stability and generalizability of the thickness controllable preparation strategy for thin lithium negative electrodes.
During the initial lithiation of the negative electrode, as Li ions are incorporated into the active material, the potential of the negative electrode decreases below 1 V (vs. Li/Li +) toward the reference electrode (Li metal), approaching 0 V in the later stages of the process.
