Chao Wang,Dongguo Li,Miaofang Chi,John E. Pearson,Rees B. Rankin,Jeffrey Greeley,Zhiyao Duan,Guofeng Wang,Dennis van der Vliet,Karren L. More,Nenad M. Markovic,Vojislav R. Stamenkovic +11 more
TL;DR: This study demonstrates that the ternary alloy catalysts can be compelling systems for further advancement of ORR electrocatalysis, reaching higher catalytic activities than bimetallic Pt alloys and improvement factors of up to 4 versus monometallic Pt.
Journal ArticleDOI
Integrated Nano-Domains of Disordered and Ordered Spinel Phases in LiNi0.5Mn1.5O4 for Li-Ion Batteries
Jung-Hyun Kim,Ashfia Huq,Miaofang Chi,Nicholas P. W. Pieczonka,Eunseok Lee,Craig A. Bridges,Misle M. Tessema,Arumugam Manthiram,Kristin A. Persson,Bob R. Powell +9 more
TL;DR: In this article, the authors systematically controlled the evolution of Ni and Mn ordering in LNMO samples by annealing them at 700 °C in air for different dwelling times, followed by quenching to room temperature.
Journal ArticleDOI
Synthesis of Homogeneous Pt-Bimetallic Nanoparticles as Highly Efficient Electrocatalysts
Chao Wang,Miaofang Chi,Dongguo Li,Dongguo Li,Dennis van der Vliet,Guofeng Wang,Qiyin Lin,John F. Mitchell,Karren L. More,Nenad M. Markovic,Vojislav R. Stamenkovic +10 more
TL;DR: In this article, a general approach for the synthesis of monodispersed and highly homogeneous Pt-bimetallic alloy nanocatalysts was introduced, which achieved a homogeneous distribution of elements, as demonstrated by atomic-scale elemental analysis using scanning transmission electron microscopy.
Journal ArticleDOI
Excellent stability of a lithium-ion-conducting solid electrolyte upon reversible Li(+) /H(+) exchange in aqueous solutions.
TL;DR: In this study, an excellent stability in neutral and strongly basic solutions was observed when using the cubic Li7 La3 Zr2 O12 garnet as a Li-stable solid electrolyte as a separator in aqueous lithium batteries.
