Journal ArticleDOI
High rate and stable cycling of lithium metal anode
Jiangfeng Qian,Wesley A. Henderson,Wu Xu,Priyanka Bhattacharya,Mark H. Engelhard,Oleg Borodin,Ji-Guang Zhang +6 more
TL;DR: It is reported that the use of highly concentrated electrolytes composed of ether solvents and the lithium bis(fluorosulfonyl)imide salt enables the high-rate cycling of a lithium metal anode at high Coulombic efficiency (up to 99.1%) without dendrite growth.
Journal ArticleDOI
Dendrite-Free Lithium Deposition via Self-Healing Electrostatic Shield Mechanism
Fei Ding,Wu Xu,Gordon L. Graff,Jian Zhang,Maria L. Sushko,Xilin Chen,Yuyan Shao,Mark H. Engelhard,Zimin Nie,Jie Xiao,Xingjiang Liu,Peter V. Sushko,Jun Liu,Ji Guang Zhang +13 more
TL;DR: This work shows a novel mechanism that can fundamentally alter dendrite formation in lithium-ion batteries as well as other metal batteries and transform the surface uniformity of coatings deposited in many general electrodeposition processes.
Journal ArticleDOI
Oxidation of Black Carbon by Biotic and Abiotic Processes
TL;DR: In this article, the authors assess the relative importance of either biotic or abiotic oxidation of biomass-derived black carbon (BC) and characterize the surface properties and charge characteristics of oxidized BC.
Journal ArticleDOI
Nitrogen-doped graphene and its electrochemical applications
Yuyan Shao,Sheng Zhang,Mark H. Engelhard,Guosheng Li,Guocheng Shao,Yong Wang,Yong Wang,Jun Liu,Ilhan A. Aksay,Yuehe Lin +9 more
TL;DR: In this paper, Nitrogen-doped graphene (N-graphene) is obtained by exposing graphene to nitrogen plasma, and it exhibits much higher electrocatalytic activity toward oxygen reduction and H2O2 reduction than graphene, and much higher durability and selectivity than the widely used expensive Pt for oxygen reduction.
Journal ArticleDOI
Activation of surface lattice oxygen in single-atom Pt/CeO2 for low-temperature CO oxidation
Lei Nie,Donghai Mei,Haifeng Xiong,Bo Peng,Zhibo Ren,Zhibo Ren,Xavier Isidro Pereira Hernandez,Andrew DeLaRiva,Meng Wang,Mark H. Engelhard,Libor Kovarik,Abhaya K. Datye,Yong Wang,Yong Wang +13 more
TL;DR: This study demonstrates how atomically dispersed ionic platinum (Pt2+) on ceria (CeO2), which is already thermally stable, can be activated via steam treatment to simultaneously achieve the goals of low-temperature carbon monoxide (CO) oxidation activity while providing outstanding hydrothermal stability.
