Recently,Chen Minghua, the associate professor from the School of Applied Sciences in Harbin University of Science and Technology, as the first author and correspondence author, cooperated with the research team in Nanyang Technological University Singapore, published the article titled “Ra;id pseudocapacitive Sodium-Ion Response Induced by Two-Dimensional Ultrathin Tin Monoxide Nanoarrays” in the international top journal named Advanced Functional Materials. This article was chosen as the cover article. Harbin University of Science and Technology is the first signature unit.

Advanced Functional Materials started publication in 2001, which is the top journal in the international materials science. The current impact factor is 11.382.

Chen Minghua went to Nanyang Technological University Singapore two times as the visiting scholar. He mainly does research in advanced carbon materials such as graphene, carbon nano-tube, etc. Up to now, he has published more than 20 SCI articles in Nano Energy, Scientific Reports and Journal of Power Sources as the first author. The total impact factor is more than 90 (among these, IF >10, two articles; IF>6, two articles; IF>4, four articles).

SIB, as new energy storage device, has received wide attention in the field. SIB can be widely applied in smart grid energy storage, peak load shifting, distributed power station and electric vehicle. The abundant sodium resources and low cost production make SIB one of the important technical direction to replace LIB.

Among numerous metal materials, Sn becomes the most promising negative material. Li17Sn4andNa15Snproduced in the process of alloying, make it have high theoretical capacity ( 959 and 847 mAhg) and very low electric potential (0.05-0.5 V). However, the unstable SEI and large volume expansion hinder the wide application. The team make ultrathin three-dimensional composite electrode with higher sodium capacity and stable recycling.

This achievement has won the China invention patent (authorization number: ZL201510069715.7). The team will base on the HUST innovation center to put the new electrode materials into production and accelerate the transformation of scientific research achievements.

This work receives the support from the National Natural Science Fund, China Postdoctoral Fund, Natural Science Foundation of Heilongjiang Province, and HUST Young Outstanding Innovative Talents.
