The study aims to enhance the performance of anode-free lithium metal batteries using a tailored covalent organic framework material.
Developed a covalent organic framework interphase layer with nitrogen-containing functional groups.
Measured lithium growth behaviors and areal capacity in lab-scale battery tests.
Evaluated battery performance metrics including rate capability and capacity.
The COF layer achieved a practical areal capacity of 4.1 mAh cm −2 and a rate capability of 3 C.
Up to 20 mAh cm −2 of lithium plating was obtained, leading to uniform lithium growth.
The COF material showed significant potential in reducing dendrite formation and enhancing battery efficiency.
