Abstract:

Lithium metal is a promising anode material for high-energy-density batteries due to its exceptionally high theoretical capacity. However, challenges such as non-uniform deposition of lithium during charge/discharge cycling, which leads to the growth of lithium dendrites, impede the commercialization of lithium-metal anodes. Herein, we developed a lithophilic NiCo2O4 (NCO) nanoneedle-modified carbonized cotton napkin (CCN) to serve as a low-cost and lightweight interlayer for lithium metal anodes. The three-dimensional carbon network provides superior electronic and ionic conductivity, while the high lithiophilicity of NCO effectively reduces the nucleation overpotential of lithium and suppresses dendrite formation. Consequently, the NCO@CCN-Li symmetric cell demonstrates a stable cycling performance of 700 h at 20 mA cm−2/10 mAh cm−2 and maintains a stable cycle for 350 h even when the current density is increased to 40 mA cm−2. Furthermore, the full cell paired with the LiFePO4 cathode (10.5 mg cm−2) retains a discharge specific capacity of 134.5 mAh g−1 after 200 cycles, with a capacity retention rate of 99.6 % and a coulombic efficiency of 99.7 %. This work provides valuable insights for the development of high-energy-density lithium-metal batteries. © 2025 Elsevier B.V.
