p-Type SnO thin layers on n-type SnS2 nanosheets with enriched surface defects and embedded charge transfer for lithium ion batteries

Abstract

In this work, for the first time, we have successfully constructed defective heterointerfaces of p-SnO on n-SnS₂ nanosheets by plasma treatment to significantly improve Li⁺ and electron diffusion kinetics. The defective heterointerfaces show advanced electrochemical performance as the anode in Li-ion batteries.
