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
Enabling High-Voltage Lithium-Metal Batteries under Practical Conditions
Xiaodi Ren,Lianfeng Zou,Xia Cao,Mark H. Engelhard,Wen Liu,Sarah D. Burton,Hongkyung Lee,Chaojiang Niu,Bethany E. Matthews,Zihua Zhu,Chongmin Wang,Bruce W. Arey,Jie Xiao,Jun Liu,Ji-Guang Zhang,Wu Xu +15 more
TL;DR: Li et al. as mentioned in this paper proposed an ether-based localized high-concentration electrolyte that can greatly enhance the stability of a Ni-rich LiNi0.8Mn0.1Co 0.1O2 (NMC811) cathode.
Journal ArticleDOI
Electrochromic mechanism in a-WO3−y thin films
TL;DR: In this paper, the electrochromic mechanism in amorphous tungsten oxide films was studied using Raman scattering measurements, and the authors concluded that the as-deposited films contain mainly the W4+ and W6+ states and the W5+ states are generated as a result of reduction of the W6+) states when lithium or hydrogen ions and electrons are inserted.
Journal ArticleDOI
Optimization of Nonaqueous Electrolytes for Primary Lithium/Air Batteries Operated in Ambient Environment
TL;DR: In this paper, the selection and optimization of nonaqueous electrolytes for ambient operations of lithium/air batteries has been studied and it has been found that PC/EC mixture is the best solvent system and LiTFSI is the most feasible salt for ambient operation of Li/Air batteries.
Journal ArticleDOI
Effects of Nonaqueous Electrolytes on the Performance of Lithium/Air Batteries
TL;DR: In this paper, the effects of various properties of nonaqueous electrolytes on the performance of lithium/air batteries are investigated, and a clear maximum in capacity is observed as a function of the electrolyte amount.
