Beyond Graphite: A Technical Deep Dive into Silicon-Carbon Composite Anodes and Volume Expansion Control
Introduction: The Theoretical Ceiling of Carbon The lithium-ion battery industry has reached a crossroads. For decades, synthetic and natural graphite have been the undisputed kings of the anode, providing a stable, reliable home for lithium ions. However, graphite is hitting its physical limit. With a theoretical maximum capacity of 372 mAh/g , there is simply no more room to squeeze more energy into a standard carbon lattice.
