Cover Feature: Elucidating ‘Transfer-Lithiation’ from Graphite to Si within Composite Anodes during Pre-Lithiation and Regular Charging (ChemSusChem 7/2025)

Abstract

The Cover Feature illustrates a charged composite anode with both graphite (Gr) and silicon (Si) active materials. The transfer lithiation from Gr to Si, driven by their potential differences, can lead to overlithiation of Si, thus material stress and degradation, even when Si is used in lower ratios.
