Avalanche-like intercalation and intraparticle correlations in graphite

Nature, Published online: 29 July 2026; doi:10.1038/s41586-026-10862-4Operando optical microscopy shows avalanche-like lithium deintercalation (intercalation) processes as the dilute stages of graphite are emptied (filled), showing how local disorder governs phase-transition dynamics and ion transport in lithium-ion battery electrodes.
