News and Updates
  • Sep. 18, 2020. Antimony trisulfide (Sb2S3)-based materials have drawn growing attention as promising anode candidates for potassium-ion batteries because of their high capacity and good working potential. On recent Advanced Functional Materials, using in-situ TEM and DFT, we investigate Sb2S3-K reaction kinetics, structural changes, and phase evolutions at the atomic scale. The potassiation of Sb2S3 involves multistep reactions including intercalation, conversion, and two-step alloying, and the final products are identified as cubic K2S and hexagonal K3Sb.

  • Sep. 11, 2020. Heteroanionic compounds are a new class of materials that contain more than one type of anion have many unique and attractive properties, which make them desirable for numerous applications. Due to challenges in synthesis and the complexity of their phase spaces, heteroanionic compounds are much less explored. On recent issue of Chemistry of Materials, we report a systematic screening for synthesizable, stable, heteroanionic oxysulfide, oxyselenide, oxytelluride compounds ABXO (A and B are metal; X = S, Se, and Te) for applications as thermoelectrics, transparent conductors, and solid-state electrolytes. Our study shows that heteroanionic compounds possess an extremely rich phase space with a variety of interesting properties and with a large number of these compounds still awaiting experimental synthesis.

  • Aug. 21, 2020. Metallic lithium is promising for high energy density Li-ion batteries while its reactivity with electrolytes and dendrite growth hinders its application.

The interface reactions with the electrolyte lead to the SEI species featuring high ionic conductivity and high stability.
