Journal ArticleDOI
Reversible aqueous zinc/manganese oxide energy storage from conversion reactions
Huilin Pan,Yuyan Shao,Pengfei Yan,Yingwen Cheng,Kee Sung Han,Zimin Nie,Chongmin Wang,Jihui Yang,Xiaolin Li,Priyanka Bhattacharya,Karl T. Mueller,Karl T. Mueller,Jun Liu +12 more
TL;DR: In this paper, the authors demonstrate a highly reversible zinc/manganese oxide system in which optimal mild aqueous ZnSO4-based solution is used as the electrolyte, and nanofibres of a manganese oxide phase, α-MnO2, are used as a cathode.
Journal ArticleDOI
High-Voltage Lithium-Metal Batteries Enabled by Localized High-Concentration Electrolytes.
Shuru Chen,Jianming Zheng,Donghai Mei,Kee Sung Han,Mark H. Engelhard,Wengao Zhao,Wu Xu,Jun Liu,Ji-Guang Zhang +8 more
TL;DR: A novel "localized high-concentration electrolyte" (HCE) is reported that enables dendrite-free cycling of lithium-metal anodes with high Coulombic efficiency (99.5%) and excellent capacity retention (80% after 700 cycles) of Li||LiNi 1/3 Mn1/3 Co1/ 3 O2 batteries.
Journal ArticleDOI
Manipulating Adsorption–Insertion Mechanisms in Nanostructured Carbon Materials for High‐Efficiency Sodium Ion Storage
Shen Qiu,Lifen Xiao,Lifen Xiao,Maria L. Sushko,Kee Sung Han,Yuyan Shao,Mengyu Yan,Xinmiao Liang,Liqiang Mai,Jiwen Feng,Yuliang Cao,Xinping Ai,Hanxi Yang,Jun Liu +13 more
TL;DR: In this paper, a series of nanostructured hard carbon materials with controlled architectures is synthesized using a combination of in situ X-ray diffraction mapping, ex situ nuclear magnetic resonance (NMR), electron paramagnetic resonance, electrochemical techniques, and simulations.
Journal ArticleDOI
Non-flammable electrolytes with high salt-to-solvent ratios for Li-ion and Li-metal batteries
Ziqi Zeng,Vijayakumar Murugesan,Kee Sung Han,Xiaoyu Jiang,Yuliang Cao,Lifen Xiao,Xinping Ai,Hanxi Yang,Ji-Guang Zhang,Maria L. Sushko,Jun Liu +10 more
TL;DR: In this article, an approach that improves the stability of non-flammable phosphate electrolytes by adjusting the molar ratio of Li salt to solvent was proposed. But their compatibility with electrode materials, especially graphite anodes, remains an obstacle owing to the strong catalytic activity of the anode surfaces.
Journal ArticleDOI
Non-encapsulation approach for high-performance Li–S batteries through controlled nucleation and growth
Huilin Pan,Junzheng Chen,Ruiguo Cao,Vijay Murugesan,Nav Nidhi Rajput,Kee Sung Han,Kee Sung Han,Kristin A. Persson,Kristin A. Persson,Luis Estevez,Mark H. Engelhard,Ji-Guang Zhang,Karl T. Mueller,Yi Cui,Yuyan Shao,Jun Liu +15 more
TL;DR: In this article, a low-surface-area, open carbon fiber architecture is used to control the nucleation and growth of the sulfur species by manipulating the carbon surface chemistry and the solvent properties, such as donor number and Li+ diffusivity.
