Higher energy and safer sodium ion batteries via an electrochemically made disordered Na3V2(PO4)2F3 material

Autor: Guochun Yan, Sathiya Mariyappan, Gwenaelle Rousse, Quentin Jacquet, Michael Deschamps, Renald David, Boris Mirvaux, John William Freeland, Jean-Marie Tarascon

Publikováno v: Nature Communications, Vol 10, Iss 1, Pp 1-12 (2019)

Na3V2(PO4)2F3 is a promising cathode material for Na-ion batteries, although its third sodium is usually not accessible electrochemically. Here the authors realize a disordered tetragonal NVPF phase, which can reversibly uptake 3 Na-ions and enables

Controlled Synthesis of NixCoyS4/rGO Composites for Constructing High-Performance Asymmetric Supercapacitor

Autor: Mingxia Dong, Zhixing Wang, Jiexi Wang, Huajun Guo, Xinhai Li, Guochun Yan

Publikováno v: Frontiers in Materials, Vol 6 (2019)

Nickel-cobalt sulfides (NixCoyS4) are promising supercapacitor materials due to their high capacitance, while the sluggish kinetics in terms of charge transfer limits their energy density. To achieve both high energy and power density for the NixCoyS
