Metal batteries have a long history, such as Zn metal batteries (e.g. Zn–C) and Li metal batteries (e.g. Li–FeS 2), which were first developed as early as 1859 and the 1940s, respectively. Due to the low redox potential and high specific capacity of metal anodes, the metal batteries possess remarkably attractive energy density.
Lithium metal, with its exceptionally high theoretical capacity, emerges as the optimal anode choice for high-energy-density rechargeable batteries. Nevertheless, the practical application of lithium metal batteries (LMBs) is constrained by issues such as lithium dendrite growth and low Coulombic efficiency (CE). Herein, a roll-to-roll approach …
