Abstract
To overcome the problems SnO2 anode faced, this work prepares porous carbon-coated SnO2 nanoplates (SnO2@C) on account of the advantages of ultrathin two-dimensional nanostructure and carbon coating on the surface, which is achieved through a simple and novel hydrothermal-assisted method. The novelty of this method is that preparing SnO2 and introducing hole making SiO2 template, which are generally achieved in steps, are successfully completed in a single hydrothermal process, thus showing relative simplicity. The results confirm that the SnO2@C shows improved kinetics, stable structure and a LiF-rich SEI layer during cycling, thereby exhibiting outstanding lithium storage performance.
期刊介绍：
Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage.
Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
