Conversion Reaction Mechanisms in Lithium Ion Batteries: Study of the Binary Metal Fluoride Electrodes
Feng Wang,R. Robert,Natasha A. Chernova,N. Pereira,Fredrick Omenya,Fadwa Badway,Xiao Hua,Michael C. Ruotolo,Ruigang Zhang,Lijun Wu,V.V. Volkov,Dong Su,Baris Key,M. Stanley Whittingham,Clare P. Grey,Clare P. Grey,Glenn G. Amatucci,Yimei Zhu,Jason Graetz +18 more
TL;DR: These results offer the first experimental evidence explaining the origins of the high lithium reversibility in FeF(2), and suggest that the massive interface formed between nanoscale solid phases provides a pathway for ionic transport during the conversion process.
Journal ArticleDOI
Composition-Structure Relationships in the Li-Ion Battery Electrode Material LiNi0.5Mn1.5O4
Jordi Cabana,Montserrat Casas-Cabanas,Fredrick Omenya,Natasha A. Chernova,Dongli Zeng,M. Stanley Whittingham,Clare P. Grey +6 more
TL;DR: The magnetic behavior of the samples was correlated with the deviations from this ideal ordering arrangement, and local deviations from the ideal 3:1 Mn:Ni ordering were found, even for samples that show the superlattice ordering by diffraction.
Journal ArticleDOI
Enhanced Li+ ion transport in LiNi0.5Mn1.5O4 through control of site disorder
Jianming Zheng,Jie Xiao,Xiqian Yu,Libor Kovarik,Meng Gu,Fredrick Omenya,Xilin Chen,Xiao-Qing Yang,Jun Liu,Gordon L. Graff,M. Stanley Whittingham,Ji Guang Zhang +11 more
TL;DR: The fundamental findings in this work can be widely applied to guide the synthesis of other mixed oxides or spinels as high performance electrode materials for lithium ion batteries.
Journal ArticleDOI
Can Vanadium Be Substituted into LiFePO4
Fredrick Omenya,Natasha A. Chernova,Shailesh Upreti,Peter Y. Zavalij,Kyung-Wan Nam,Xiao-Qing Yang,M. Stanley Whittingham +6 more
TL;DR: In this paper, vanadium is shown to substitute for iron in the olivine LiFePO4 up to at least 10 mol %, when the synthesis is carried out at 550 °C.
Journal ArticleDOI
Rock-Salt Growth-Induced (003) Cracking in a Layered Positive Electrode for Li-Ion Batteries
Hanlei Zhang,Fredrick Omenya,Pengfei Yan,Langli Luo,M. Stanley Whittingham,Chongmin Wang,Guangwen Zhou +6 more
TL;DR: In this article, the authors used transmission electron microscopy techniques to show that the propagation and fracturing of platelet-like rock-salt phase along the (003) plane of the layered oxide are the leading cause for the cracking of primary particles.
