Slight compositional variation-induced structural disorder-to-order transition enables fast Na+ storage in layered transition metal oxides
Autor: Yuansheng Shi, Pengfeng Jiang, Shicheng Wang, Weixin Chen, Bin Wei, Xueyi Lu, Guoyu Qian, Wang Hay Kan, Huaican Chen, Wen Yin, Yang Sun, Xia Lu
Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-12 (2022)
In layered transition metal oxides as cathode active materials for Na-ion batteries, Na+ diffusion kinetics are impacted by Na+/vacancy ordering. Here, the authors suggest that the P2-type Na2/3Ni1/3Mn2/3O2 with large zigzag ordering exhibits high Na

Lithiated Prussian blue analogues as positive electrode active materials for stable non-aqueous lithium-ion batteries
Autor: Ziheng Zhang, Maxim Avdeev, Huaican Chen, Wen Yin, Wang Hay Kan, Guang He
Publikováno v: Nature Communications, Vol 13, Iss 1, Pp 1-13 (2022)
Prussian blue analogues (PBAs) are appealing materials for aqueous Na- and K- ion batteries but are limited for non-aqueous Li-ion storage. Here, the authors report the synthesis of various lithiated PBAs and discuss critical factors for improving th

Layered-rocksalt intergrown cathode for high-capacity zero-strain battery operation
Autor: Ning Li, Meiling Sun, Wang Hay Kan, Zengqing Zhuo, Sooyeon Hwang, Sara E. Renfrew, Maxim Avdeev, Ashfia Huq, Bryan D. McCloskey, Dong Su, Wanli Yang, Wei Tong
Publikováno v: Nature Communications, Vol 12, Iss 1, Pp 1-10 (2021)
The dependence on lithium-ion batteries leads to a pressing demand for advanced cathode materials. Here the authors report a new concept of layered-rocksalt intergrown structure that enables nearly zero-strain operation upon high-capacity cycling, of

Alleviating oxygen evolution from Li-excess oxide materials through theory-guided surface protection
Autor: Yongwoo Shin, Wang Hay Kan, Muratahan Aykol, Joseph K. Papp, Bryan D. McCloskey, Guoying Chen, Kristin A. Persson
Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-8 (2018)
Rechargeable Li-ion batteries can show extensive oxygen loss from the cathode material under operating conditions. Here, the authors use high-throughput computational screening to guide the synthesis of a Tantalum-doped Li-excess cathode that signifi
