Journal ArticleDOI
ZnS-SnS@NC Heterostructure as Robust Lithiophilicity and Sulfiphilicity Mediator toward High-Rate and Long-Life Lithium-Sulfur Batteries.
TL;DR: In this article, a ZnS-SnS heterojunction with a polydopamine-derived N-doped carbon shell was obtained and compared with its single component counterparts (SnS@NC and SnS2@NC).
Journal ArticleDOI
Deeply Nesting Zinc Sulfide Dendrites in Tertiary Hierarchical Structure for Potassium Ion Batteries: Enhanced Conductivity from Interior to Exterior.
Jianhua Chu,Wei Alex Wang,Jianrui Feng,Cheng-Yen Lao,Kai Xi,Lidong Xing,Kun Han,Qiang Li,Lei Song,Ping Li,Xin Li,Yanping Bao +11 more
TL;DR: Using density functional theory calculations, it is discovered the interactions between ZnS and carbon interface can effectively decrease the K+ ions diffusion barrier and therefore promote the reversibility of K-ion batteries storage.
Journal ArticleDOI
Hollow Multihole Carbon Bowls: A Stress-Release Structure Design for High-Stability and High-Volumetric-Capacity Potassium-Ion Batteries.
Zili Zhang,Zili Zhang,Jia Baorui,Jia Baorui,Liu Luan,Zhao Yongzhi,Wu Haoyang,Mingli Qin,Mingli Qin,Kun Han,Wei Alex Wang,Kai Xi,Lin Zhang,Genggeng Qi,Xuanhui Qu,Ramachandran Vasant Kumar +15 more
TL;DR: This work simulates the von Mises stress distributions of four different carbon three-dimensional models under an isotropic initial stress by the finite element method and reveals the critical role of the structure of hollow multihole bowl on the strain-relaxation behavior.
Journal ArticleDOI
High-throughput fabrication of 3D N-doped graphenic framework coupled with Fe3C@porous graphite carbon for ultrastable potassium ion storage
Kun Han,Zhiwei Liu,Ping Li,Qiyao Yu,Wei Wang,Wei Wang,Cheng-Yen Lao,Donglin He,Wang Zhao,Suo Guoquan,Hao Guo,Lei Song,Mingli Qin,Xuanhui Qu +13 more
TL;DR: In this article, a 3D N-doped graphenic framework coupled with Fe3C@porous graphite carbon core-shell structures was designed for potassium-ion battery.
Journal ArticleDOI
Zero-strain K0.6Mn1F2.7 hollow nanocubes for ultrastable potassium ion storage
Zhiwei Liu,Ping Li,Suo Guoquan,Sheng Gong,Wei Wang,Wei Wang,Cheng-Yen Lao,Yajie Xie,Hao Guo,Qiyao Yu,Wang Zhao,Kun Han,Qian Wang,Mingli Qin,Kai Xi,Xuanhui Qu +15 more
TL;DR: In this paper, a new etching route was proposed to fabricate a zero-strain potassium fluoromanganate hollow nanocubes (KMnF-NCs) for boosting the performance of KIBs in terms of capacity, rate capability and cycling stability.
