Journal ArticleDOI
Fast and reversible zinc ion intercalation in Al-ion modified hydrated vanadate
Jiqi Zheng,Jiqi Zheng,Chaofeng Liu,Meng Tian,Xiaoxiao Jia,Evan P. Jahrman,Gerald T. Seidler,Shaoqing Zhang,Yanyan Liu,Yifu Zhang,Changgong Meng,Guozhong Cao +11 more
TL;DR: In this article, trivalent vanadium oxides (Al-ions) were introduced during a one-step hydrothermal synthesis to enable rapid Zn2+ diffusion and electron transfer.
Journal ArticleDOI
Structural engineering of hydrated vanadium oxide cathode by K+ incorporation for high-capacity and long-cycling aqueous zinc ion batteries
Meng Tian,Meng Tian,Chaofeng Liu,Jiqi Zheng,Xiaoxiao Jia,Evan P. Jahrman,Gerald T. Seidler,Donghui Long,Muhammad Atif,Mohamad S. AlSalhi,Guozhong Cao +10 more
TL;DR: In this article, a structural engineering method by incorporating K+ into hydrated vanadium pentoxide (V2O5·nH2O, VOH) was reported to achieve a new phase of KVOH with faster ion diffusion kinetics and better long-term cycling stability.
Journal ArticleDOI
An improved laboratory-based x-ray absorption fine structure and x-ray emission spectrometer for analytical applications in materials chemistry research
Evan P. Jahrman,William M. Holden,Alexander S. Ditter,Devon R. Mortensen,Gerald T. Seidler,Timothy T. Fister,Stosh A. Kozimor,Louis F. J. Piper,Jatinkumar Rana,Neil C. Hyatt,Martin C. Stennett +10 more
TL;DR: The design and performance of an improved XAFS and XES spectrometer based on the general conceptual design of Seidler et al. are reported, which enables a new class of routine applications that are incompatible with the mission and access model of the synchrotron light sources.
Journal ArticleDOI
Interface Engineering V 2 O 5 Nanofibers for High‐Energy and Durable Supercapacitors
Wenchao Bi,Wenchao Bi,Jichao Wang,Evan P. Jahrman,Gerald T. Seidler,Guohua Gao,Guangming Wu,Guozhong Cao +7 more
TL;DR: As the charge transfer kinetics are synergistically enhanced by the dual modifications, Vö-V2 O5 /PANI-based supercapacitors exhibit an excellent specific capacitance as well as a long cycling lifespan (110% of capacitance remained after 20 000 cycles).
Journal ArticleDOI
An Improved Laboratory-Based XAFS and XES Spectrometer for Analytical Applications in Materials Chemistry Research
Evan P. Jahrman,William M. Holden,Alex S. Ditter,Devon R. Mortensen,Gerald T. Seidler,T. T. Fister,Stosh A. Kozimor,Louis F. J. Piper,Jatinkumar Rana,Neil C. Hyatt,Martin C. Stennett +10 more
TL;DR: In this paper, the authors report the design and performance of an improved spectrometer XAFS and XES based on the general conceptual design of Seidler, et al., which enables a new class of routine applications that are incompatible with the mission and access model of synchrotron x-ray light sources.
