Simultaneously Dual Modification of Ni-Rich Layered Oxide Cathode for High-Energy Lithium-Ion Batteries
Huiping Yang,Hong-Hui Wu,Mingyuan Ge,Lingjun Li,Yifei Yuan,Qi Yao,Jie Chen,Lingfeng Xia,Jiangming Zheng,Zhaoyong Chen,Junfei Duan,Kim Kisslinger,Xiao Cheng Zeng,Wah-Keat Lee,Qiaobao Zhang,Jun Lu +15 more
TL;DR: In this article, a dual-modification strategy of synchronous synthesis and in situ modification of LiNi0.8Co0.1Mn 0.1O2 cathodes was proposed to solve the problem of fast capacity drop and voltage fading due to the interfacial instability and bulk structural degradation of the cathodes during battery operation.
Journal ArticleDOI
Tracheal Respiration in Insects Visualized with Synchrotron X-ray Imaging
Mark W. Westneat,Oliver Betz,Oliver Betz,Richard W. Blob,Richard W. Blob,Kamel Fezzaa,W. James Cooper,W. James Cooper,Wah-Keat Lee +8 more
TL;DR: Insects, crickets, and ants exhibited rapid cycles of tracheal compression and expansion in the head and thorax analogous to the inflation and deflation of vertebrate lungs.
Journal ArticleDOI

TL;DR: In this paper, a sulfonamide-based electrolyte was designed to enable stable cycling of LiNi0.8Co0.1O2 with a cut-off voltage up to 4.7
Journal ArticleDOI
Surface regulation enables high stability of single-crystal lithium-ion cathodes at high voltage.
Fang Zhang,Shuaifeng Lou,Shuang Li,Zhenjiang Yu,Qingsong Liu,Alvin Dai,Chuntian Cao,Michael F. Toney,Mingyuan Ge,Xianghui Xiao,Wah-Keat Lee,Yudong Yao,Junjing Deng,Tongchao Liu,Yiping Tang,Geping Yin,Jun Lu,Dong Su,Jiajun Wang +18 more
TL;DR: This work investigates the correlation of the surface structure, internal strain, and capacity deterioration by using operando X-ray spectroscopy imaging and nano-tomography and discovers that surface chemistry can significantly enhance the cyclic performance.
Journal ArticleDOI
Hard x-ray microscopy with Fresnel zone plates reaches 40 nm Rayleigh resolution.
