Origin of additional capacities in metal oxide lithium-ion battery electrodes
Yan-Yan Hu,Zigeng Liu,Kyung-Wan Nam,Olaf J. Borkiewicz,Jun Cheng,Xiao Hua,Matthew T. Dunstan,Xiqian Yu,Kamila M. Wiaderek,Lin-Shu Du,Karena W. Chapman,Peter J. Chupas,Xiao-Qing Yang,Claire P. Grey,Claire P. Grey +14 more
TL;DR: High-resolution multinuclear/multidimensional solid-state NMR techniques are used with in situ synchrotron-based techniques to study the prototype conversion material RuO2, demonstrating a protocol for studying the structure and spatial proximities of nanostructures formed in this system, including the amorphous solid electrolyte interphase that grows on battery electrodes.
Journal ArticleDOI
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
Comprehensive Study of the CuF2 Conversion Reaction Mechanism in a Lithium Ion Battery
Xiao Hua,Xiao Hua,R. Robert,Lin-Shu Du,Kamila M. Wiaderek,Michal Leskes,Karena W. Chapman,Peter J. Chupas,Clare P. Grey,Clare P. Grey +9 more
TL;DR: In this paper, the reaction mechanisms that occur in the first and subsequent cycles and the reasons for the poor charge performance of CuF2 are studied via a variety of characterization methods, including in situ pair distribution function analysis.
Journal ArticleDOI
Multiple Redox Modes in the Reversible Lithiation of High-Capacity, Peierls-Distorted Vanadium Sulfide
Sylvia Britto,Michal Leskes,Xiao Hua,Claire-Alice Hébert,Hyeon Suk Shin,Simon J. Clarke,Olaf J. Borkiewicz,Karena W. Chapman,Ram Seshadri,Jaephil Cho,Clare P. Grey +10 more
TL;DR: V NMR shows that the material, despite having V formally in the d(1) configuration, is diamagnetic, suggesting potential dimerization through metal-metal bonding associated with a Peierls distortion of the linear chains, supported by density functional calculations and consistent with the observed alternation in V-V distances.
Journal ArticleDOI
Flash Infrared Annealing for Antisolvent-Free Highly Efficient Perovskite Solar Cells
TL;DR: In this article, an antisolvent-free method that can be used to prepare methylammonium lead iodide (MAPbI3) PSCs with stabilized power conversion efficiencies up to 18.3% is presented.
