Dai, Hanqing (author), Xu, Wenqian (author), Hu, Zhe (author), Chen, Yuanyuan (author), Gu, Jing (author), Xie, Fengxian (author), Wei, Wei (author), Guo, Ruiqian (author), Zhang, Kouchi (author)NaTi2(PO4)3 (NTP), a well-known anode material, could be used as a solid wide-band gap electrolyte. Herein, a novel solid-state sodium-ion battery (SSIB) with the thickness of electrolyte up to the millimeter level is proposed. The results of the difference in charge density investigated by the first-principles calculations imply that using...journal article 2021

Dai, Hanqing (author), Xu, Wenqian (author), Hu, Zhe (author), Gu, Jing (author), Chen, Yuanyuan (author), Guo, Ruiqian (author), Zhang, Kouchi (author), Wei, Wei (author)Previously, α-Fe2O3 nanocrystals are recognized as anode materials owing to their high capacity and multiple properties. Now, this work provides high-voltage α-Fe2O3 nanoceramics cathodes fabricated by the solvothermal and calcination processes for sodium-ion batteries (SIBs). Then, their structure and electrical conductivity were...journal article 2021
