However, the large-scale application solid garnet electrolytes is restricted by interfacial resistance poor wettability metallic voids caused sluggish lithium-ion transport during plating/stripping. Herein, we propose three-dimensional (3D) composite anode with electronic conductivity introducing small amount carbonized ZIF-8 powder into molten lithium, achieving compact contact remarkably low 15.2 Ω cm2 decreased surface tension lithium. Aided DFT calculations, are able confirm that reaction products Li3N, Li2O, Li-Zn alloy, LiC6 have much lower formation energies compared pure anode. lithiophobic Li3N Li2O could impede dendrite growth, provide rapid transport, thus prevent reduction. In addition, lithiophilic alloy accelerate migration, preventing at interface. Thus, so-called cocktail effects would occur boost electrochemical performance through synergistic interactions. symmetric battery enabled achieves an impressive CCD 2.5 mA cm-2 stable galvanostatic cycling for 350 h without short-circuiting 0.5 cm-2.

Herein, we find interphase engineering is crucial process and polymer pioneer an polymerization-fluorination (Poly-FR) strategy to create durable interfaces with excellent stabilities, achieved by designing bifunctional initiator both on-surface lithium donor reactions. The integrated fluorination converts Li2CO3 impurities on LiNi0.8Co0.1Mn0.1O2 (NCM811) surfaces into LiF-rich interphases, effectively inhibiting aggressive (de)lithiation intermediates protecting interface from underlying chemical degradation, thereby surpassing limitations alone. Furthermore, Poly-FR mediated symmetric Li|Li cells achieve impressive cycling up 12,000 h.
