Journal ArticleDOI
A ZnCl2 water-in-salt electrolyte for a reversible Zn metal anode.
Chong Zhang,Chong Zhang,John Holoubek,Xianyong Wu,Aigerim Daniyar,Liangdong Zhu,Cheng Chen,Daniel P. Leonard,Ismael A. Rodríguez-Pérez,Jia-Xing Jiang,Chong Fang,Xiulei Ji +11 more
TL;DR: A low-cost water-in-salt electrolyte, of 30 m ZnCl2, which enables a dendrite-free Zn metal anode to possess a high coulombic efficiency (CE) in asymmetric Zn‖Zn cells with a limited mass of plated Zn as the working electrode.
Journal ArticleDOI
Tailoring Electrolyte Solvation for Li Metal Batteries Cycled at Ultra-Low Temperature.
John Holoubek,Haodong Liu,Zhaohui Wu,Yijie Yin,Xing Xing,Guorui Cai,Sicen Yu,Hongyao Zhou,Tod A. Pascal,Zheng Chen,Ping Liu +10 more
TL;DR: In this paper, the role of solvation structures of Li-ions in the charge-transfer kinetics was discussed and an electrolyte was designed to enable low-temperature operations of LMBs.
Journal ArticleDOI
An All-Fluorinated Ester Electrolyte for Stable High-Voltage Li Metal Batteries Capable of Ultra-Low-Temperature Operation
John Holoubek,Mingyu Yu,Sicen Yu,Minqian Li,Zhaohui Wu,Dawei Xia,Pranjal Bhaladhare,Matthew Gonzalez,Tod A. Pascal,Ping Liu,Zheng Chen +10 more
TL;DR: In this article, the authors proposed a method to improve the energy output of batteries at sub-zero temperatures, which can generally be accomplished by emplacement of the battery in the battery charger.
Journal ArticleDOI
Ultra-fast NH4+ Storage: Strong H Bonding between NH4+ and Bi-layered V2O5
Shengyang Dong,Shengyang Dong,Woochul Shin,Heng Jiang,Xianyong Wu,Zhifei Li,John Holoubek,William F. Stickle,Baris Key,Cong Liu,Jun Lu,P. Alex Greaney,Xiaogang Zhang,Xiulei Ji +13 more
TL;DR: In this paper, the authors show that the use of NH4+ results in battery performance governed by the chemical nature of the ion-electrode interaction, and they show that H bonding between NH4+, and a bi-layered V2O5 electrode is coupled with prominent pseudocapacitive behavior.
Journal ArticleDOI
Insights on the Proton Insertion Mechanism in the Electrode of Hexagonal Tungsten Oxide Hydrate.
Heng Jiang,Jessica J. Hong,Xianyong Wu,T. Wesley Surta,Yitong Qi,Shengyang Dong,Shengyang Dong,Zhifei Li,Daniel P. Leonard,John Holoubek,Jane C. Wong,Joshua J. Razink,Xiaogang Zhang,Xiulei Ji +13 more
TL;DR: Ex situ XRD reveals that protonation of the WO3 hydrate causes consecutive anisotropic structural changes: it first contracts along the c-axis but later expands along the ab planes, together with appreciable capacity and promising rate performance.
