In article number 1802534 , Neil P. Dasgupta and co‐workers report a 3D current collector architecture based on vertically‐aligned Cu pillars for Li metal anodes. By rationally tuning geometric parameters and surface chemistry by ALD coatings, the morphology of Li plating/stripping can be controlled. Leveraging the synergistic effects of the optimized geometry and interface modification, cycling of Li metal anodes is demonstrated with Coulombic efficiency up to 99.5%.
