XMUM Research Publication in Nanoscale – A Tier-1 SCI Journal


The Office of Research and Innovation congratulates Associate Professor Dr. Zhang Ying on her role as one of the corresponding authors of a publication entitled “Ultrafine Mo-doped SnO2 nanostructure and derivative Mo-doped Sn/C nanofibers for high-performance lithium-ion batteries.” The paper was published on 28 August 2018 (vol. 10 and pages 17378-17387) in Nanoscale, a high impact, peer reviewed journal publishing experimental and theoretical work across the breadth of nanoscience and nanotechnology. Assoc. Prof. Dr. Zhang Ying, from Xiamen University Malaysia, co-authored the paper with 8 other scientists affiliated to Xiamen University, China.

The study focuses on developing tin-based materials as attractive candidates for high-capacity and long-cycle-life anodes in Li-ion batteries (LIBs) owing to their low cost and high energy density. However, the materials suffer from severe structural decay during the lithium ion insertion/extraction process, which results in deterioration in the overall performance of the batteries. To mitigate this problem, a Mo-doped SnO2 nanostructure have been synthesized via a facile hydrothermal method, which then fragmented into ultrafine particles after dozens of cycles.

The research team found that the fracture-resistant size and ample contact with Super-P and Li2O greatly improved the electrochemical kinetics and cyclability to deliver a reversible capacity of 670 mA h g−1 after 700 cycles. The compounds were also uniformly dispersed in carbon nanofibers and reduced in situ to prepare a free-standing anode via electrospinning and carbonization. The importance of the finding is: the nanofiber membrane anode is able to deliver comparable cycling performance and capacity to that of a slurry-coated electrode, which infers their potential as a free-standing anode for LIBs.

Assoc. Prof. Dr. Zhang Ying contributes extensively in the peer review process and publication cycle. She provides the intellectual input, designs the research direction, and sets the protocols to be followed in the study. She is responsible for the correction and proof reading of the manuscripts; the correspondence process during paper submission; and the handling of the revision and re-submission of revised manuscripts up to the acceptance of the final manuscript.
