Jun Lu,Yun Jung Lee,Xiangyi Luo,Xiangyi Luo,Kah Chun Lau,Mohammad Asadi,Hsien-Hau Wang,Scott M. Brombosz,Jianguo Wen,Dengyun Zhai,Zonghai Chen,Dean J. Miller,Yo Sub Jeong,Jin Bum Park,Zhigang Zak Fang,Bijandra Kumar,Amin Salehi-Khojin,Yang-Kook Sun,Larry A. Curtiss,Khalil Amine +19 more
TL;DR: It is shown that crystalline LiO2 can be stabilized in a Li–O2 battery by using a suitable graphene-based cathode, which could open the way to high-energy-density batteries based onLiO2 as well as to other possible uses of this compound, such as oxygen storage.
Journal ArticleDOI
A nanostructured cathode architecture for low charge overpotential in lithium-oxygen batteries
Jun Lu,Yu Lei,Kah Chun Lau,Xiangyi Luo,Peng Du,Jianguo Wen,Rajeev S. Assary,Ujjal Das,Dean J. Miller,Jeffrey W. Elam,Hassan M. Albishri,D. Abd El-Hady,Yang-Kook Sun,Larry A. Curtiss,Khalil Amine,Khalil Amine +15 more
TL;DR: A cathode architecture based on nanoscale components that results in a dramatic reduction in charge overpotential to ~0.2 V is reported, which provides the basis for future development of lithium-oxygen cathode materials that can be used to improve the efficiency and to extend cycle life.
Journal ArticleDOI
A lithium–oxygen battery with a long cycle life in an air-like atmosphere
Mohammad Asadi,Mohammad Asadi,Baharak Sayahpour,Pedram Abbasi,Anh T. Ngo,Klas Karis,Jacob R. Jokisaari,Cong Liu,Badri Narayanan,Marc Gerard,Poya Yasaei,Xuan Hu,Arijita Mukherjee,Kah Chun Lau,Rajeev S. Assary,Fatemeh Khalili-Araghi,Robert F. Klie,Larry A. Curtiss,Amin Salehi-Khojin +18 more
TL;DR: A system comprising a lithium carbonate-based protected anode, a molybdenum disulfide cathode and an ionic liquid/dimethyl sulfoxide electrolyte that operates as a lithium–air battery in a simulated air atmosphere with a long cycle life of up to 700 cycles is reported.
Journal ArticleDOI
Facet-dependent active sites of a single Cu 2 O particle photocatalyst for CO 2 reduction to methanol
Yimin A. Wu,Yimin A. Wu,Ian McNulty,Cong Liu,Kah Chun Lau,Kah Chun Lau,Qi Liu,Arvydas P. Paulikas,Cheng-Jun Sun,Zhonghou Cai,Jeffrey R. Guest,Yang Ren,Vojislav R. Stamenkovic,Larry A. Curtiss,Yuzi Liu,Tijana Rajh +15 more
TL;DR: Wu et al. as discussed by the authors used correlated scanning fluorescence X-ray microscopy and environmental transmission electron microscopy at atmospheric pressure to identify the active facets for CO2 reduction on Cu2O and exploit this to obtain high conversion efficiency and selectivity to methanol.
Journal ArticleDOI
Disproportionation in Li–O2 Batteries Based on a Large Surface Area Carbon Cathode
Dengyun Zhai,Hsien-Hau Wang,Junbing Yang,Kah Chun Lau,Kaixi Li,Khalil Amine,Larry A. Curtiss +6 more
TL;DR: A kinetics study of the discharge process and its relationship to the charge overpotential in a Li-O2 cell for large surface area cathode material reveals evidence for a first-order disproportionation reaction during discharge from an oxygen-rich Li2O2 component with superoxide-like character to a Li2 O2 component.
