| Abstract Scope |
Lithium metal anodes offer the highest theoretical capacity(3860 mAhg-1) for next-generation batteries but suffer from dendrite growth, volume fluctuations, voids and dead Li formation during cycling, causing poor cycling capacity retention, low rate capability, and safety concerns. Herein, a synergistic anode architecture integrating a lithiophilic modified 3D skeleton with a protective coating layer is prepared via roll-pressing/coating. This process enables scalable fabrication of ultra-thin(≤50μm) lithium metal composites with ≥80×80mm2 dimensions. The lithiophilic 3D framework guides uniform Li+ flux and mitigates volume expansion, while the coating suppresses dendrites and stabilizes interfaces. As a result, Li@3D/Li@3D symmetrical cells achieve a long lifespan over 500h cycling at 1 mA cm-2 and 1mAh cm-2. The performance of full cell against high nickel content NCM cathode achieves a capacity of 178 mAhg-1 at 1C with over 90% capacity retention after 100 cycles. This strategy demonstrates high-performance lithium metal batteries with scalable manufacturability. |
