Silicon anodes can greatly boost the energy density of all-solid-state batteries, but their large volume changes often cause contact loss with solid electrolytes. Si can store more lithium than graphite, but its volume can expand by as much as 410% during charging, generating mechanical stress that cracks particles and weakens their contact with the solid… Read more »
