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.
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.
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.
The main problem is the high voltage (1.8 V) of the plateau, particularly as compared with carbon materials. Again this can be solved by combination with a sufficiently high potential positive electrode in a lithium-ion battery.
More recently, a new perspective has been envisaged, by demonstrating that some binary oxides, such as CoO, NiO and Co 3 O 4 are interesting candidates for the negative electrode of lithium-ion batteries when fully reduced by discharge to ca. 0 V versus Li , .
