Overview

Experimental study reveals enhanced cycling reversibility in anode-free lithium metal batteries, highlighting the potential of sub-nano interphase engineering for stable energy storage.

Key Points

To enhance the cycling reversibility and operational lifespan of anode-free lithium metal batteries by mitigating sluggish lithium-ion transport, unwanted parasitic side reactions, and dendrite formation.
Electrosynthesized a ~200 nm zeolitic imidazolate framework-8 (ZIF-8) interphase layer onto copper current collectors (Cu@ZIF-8).
Engineered sub-nanometer windows and internal cavities within the ZIF-8 layer to serve as an anion reservoir, accelerating desolvation kinetics and promoting a LiF- and Li3N-rich solid-electrolyte interphase.
Assessed electrochemical reversibility via Aurbach coulombic efficiency in Li/Cu@ZIF-8 cells and evaluated long-term cycling performance in Cu@ZIF-8/LiFePO4 full cells.
Li/Cu@ZIF-8 asymmetric cells achieved an Aurbach coulombic efficiency of 99.84%.
Full Cu@ZIF-8/LiFePO4 anode-free lithium metal batteries demonstrated 57.8% capacity retention after 400 cycles.
