Lithium metal offers high specific capacity but suffers from dendrite growth and poor cycling stability. Here, authors develop a 3D Li-Zn-Li3N/CNT composite combining ductile Li-Zn alloy and a mechanically robust Li3N-CNTs network, enabling thin, durable electrodes with uniform lithium deposition, demonstrating a pouch-cell with a specific energy of 553 Wh kg-1.
