William E. Gent,Kipil Lim,Yufeng Liang,Qinghao Li,Taylor Barnes,Sungjin Ahn,Kevin H. Stone,Mitchell McIntire,Jihyun Hong,Jihyun Hong,Jay-Hyok Song,Yiyang Li,Apurva Mehta,Stefano Ermon,Tolek Tyliszczak,David Kilcoyne,David Vine,Jin-Hwan Park,Seok-Kwang Doo,Michael F. Toney,Wanli Yang,David Prendergast,William C. Chueh,William C. Chueh +23 more
TL;DR: The authors reveal that the voltage of anion redox is strongly affected by structural changes that occur during battery cycling, explaining its unique electrochemical properties.
Journal ArticleDOI
Evidence of reversible oxygen participation in anomalously high capacity Li- and Mn-rich cathodes for Li-ion batteries
Shoaib Muhammad,Hyunchul Kim,Yunok Kim,Donghwi Kim,Jay-Hyok Song,Jaegu Yoon,Jin-Hwan Park,Sungjin Ahn,Sun-Ho Kang,Michael M. Thackeray,Won-Sub Yoon +10 more
TL;DR: In this paper, high-resolution synchrotron X-ray powder diffraction (HRPD) and Xray absorption spectroscopy (XAS) were used, respectively, to evaluate the electrochemical charge and discharge reactions in terms of local and bulk structural changes, and variations in the oxidation states of the transition metal ions.
Journal ArticleDOI
Suppression of irreversible capacity loss in Li-rich layered oxide by fluorine doping
TL;DR: In this article, the authors proposed that the presence of fluorine facilitated the reduction of cobalt and manganese ions in Li-rich layered oxide, and that reduced transition metal (TM) ions suppressed structural changes.
Journal ArticleDOI
Emission properties of PbO−Bi2O3−Ga2O3−GeO2 glasses doped with Tm3+ and Ho3+
TL;DR: In this article, the authors investigated the potential hosts for 1.48 μm fiber-optic amplifiers using heavy metal oxide glasses containing GeO2 and obtained the optimum glass composition for the Tm3+:3H4 level, where the concentration of codoped Ho3+ exceeded 0.2 mol %.
Journal ArticleDOI
New fast-decaying green and red phosphors for 3D application of plasma display panels
TL;DR: In this paper, the luminescence properties of new phosphors for 3D PDP application were presented and the development of fast-decaying PDP phosphors has enabled commercialization of 3D/2D switchable PDP television for the first time in PDP industry.
