However, the critical issue of the intractable growth of Li dendrites, which leads to a poor cycling life, still remains. Herein, a hierarchical surface is designed and constructed on carbon fiber (CF) using binders in fabricated CF paper (CFP). The lightweight CF with high mechanical properties is facilitated to establish a 3D network structure as an alternative to Cu foil. The binders are transformed into oxygen-containing amorphous carbon and sodium carbonate (Na2CO3) using a low-temperature carbonization process, leading to uniform Li nucleation and a stable solid electrolyte interphase layer with inorganic components. In the electrochemical test, the CFP with amorphous carbon and Na2CO3 (ANCFP) shows a low Li nucleation overpotential and smooth dendrite-free Li plating. Furthermore, the ANCFP electrode exhibits good cycling stability in half and symmetrical cells. A full-cell assembled using a LiFePO4 cathode with high loading (approximate to 13 mg cm(-2)) achieves a high-energy density of 428 Wh kg(-1) (at 0.1 C) and an excellent capacity retention of 85% at 1 C after 300 cycles. This strategy is expected to help realize highly stable Li metal anodes for practical application by suppressing Li dendrite growth.
