Quantifying lithium loss in amorphous silicon thin-film anodes via titration-gas chromatography
Silicon with a high theoretical capacity (3,579 mAh/g) is a promising anode candidate for
lithium-ion batteries. However, commercialization is still impeded by low Coulombic
efficiency, caused by solid electrolyte interphase (SEI) formation and trapped lithium (Li)-
silicon (Si) alloy during repeated volume change. Quantifying capacity losses from each
factor is crucial to formulate rational design strategies for further improvement. In this work,
titration-gas chromatography and cryogenic transmission electron microscopy are applied to …
