Oxidation Loss

The limitation of a high-voltage lithium (Li) metal battery lies in the absence of a robust electrolyte that can endure oxidation loss at a high-voltage cathode and suppress the dendrite growth at a Li metal anode.

Superior Cycling Stability

A more superior cycling stability and a higher utilization ratio of the Li metal anode have been achieved by additive- and nanostructure-stabilized SEI layers. A profound understanding of the composition, internal structure, and evolution of the SEI film sheds new light on dendrite-free high-efficiency lithium metal batteries.

AbstractLithium reactivity with electrolytes leads to their continuous consumption and dendrite growth, which constitute major obstacles to harnessing the tremendous energy of lithium-metal anode in a reversible manner. Considerable attention has been focused on inhibiting dendrite via interface and electrolyte engineering, while admitting electrolyte-lithium metal reactivity as a thermodynamic inevitability. Here, we report the effective suppression of such reactivity through a nano-porous separator. Calculation assisted by diversified characterizations reveals that the separator partially desolvates Li+ in confinement created by its uniform nanopores, and deactivates solvents for electrochemical reduction before Li0-deposition occurs. The consequence of such deactivation is realizing dendrite-free lithium-metal electrode, which even retaining its metallic lustre after long-term cycling in both Li-symmetric cell and high-voltage Li-metal battery with LiNi0.6Mn0.2Co0.2O2 as cathode. The discovery that a nano-structured separator alters both bulk and interfacial behaviors of electrolytes points us toward a new direction to harness lithium-metal as the most promising anode.
