Battery development needs both scientific and engineering breakthroughs. Starting from an atomic understanding of particle growth mechanisms, a remarkable upscaling of a sub-nanometer-sized silicon-based negative electrode — from coin-sized cells to battery packs of over 100 kWh — is now presented.
