CONCLUSIONS
In summary, an advanced 3D skeleton (ZSONT/CC) was developed to serve as
lithium metal host with both structural and compositional homogeneity
for high-performance LMBs. Upon lithiation, the in-situ
formed Li2S-Li2O-LiZn rich SEI on 3D
carbon host efficiently guided the uniform lithium deposition,
stabilized the electrolyte-electrode interface, and facilitated
Li+ ion transport in the repeating lithium
plating/stripping process. As a result, excellent cycle stability was
maintained when Li/ZSONT/CC anode was applied in symmetrical cells and
full cells, and a high CE was achieved. This work provides an effective
design strategy for SEI formation on a 3D electrode host with possible
control on the SEI content.
