Fig. 5. Electrochemical performance of different anodes in the half cells with the ether electrolyte.

(A) CE versus cycle number plots of the anodes based on NMMF@C-Cu, NMMF-Cu, and b-Cu. (B) Electrochemical Li plating/stripping curves of the NMMF@C-Cu anode at 1 mA cm⁻² with a specific capacity of 1 mAh cm⁻². (C) Magnification of the red rectangular region in (B). (D) Galvanostatic discharge/charge voltage curves of Cu-Li and NMMF@C-Li anodes in symmetric coin cells at 1 mA cm⁻².
