Our 2D-PRINTABLE partner from TCD published a new article: “Liquid-Phase Exfoliation of Arsenic Trisulfide (As2S3) Nanosheets and Their Use as Anodes in Potassium-Ion Batteries”, featured in ACS Nano.
This study demonstrates the production of 2D arsenic disulfide (As2S3) nanosheets through liquid-phase exfoliation of the naturally occurring mineral – orpiment. The nanosheets, with lateral dimensions of 400 nm and a thickness of 10 nm, were mixed with carbon nanotubes to create nanocomposite films for use as anodes in potassium-ion batteries. These anodes exhibited outstanding performance, with a discharge capacity of 619 mAh/g at a current density of 50 mA/g and 94% capacity retention after 1000 cycles at 500 mA/g. The impressive theoretical capacity, high efficiency, and strong capacity retention of these nanosheets position them as promising candidates for next-generation potassium-ion battery (KIB) applications. Future research should aim to address rate performance challenges to fully unlock their potential for practical energy storage solutions.
Congratulations to TCD on this remarkable achievement!
