Boosted Supercapacitive Energy with High Rate Capability of aCarbon Framework with Hierarchical Pore Structure in an Ionic Liquid
Wang, Xuehang; Zhou, Haitao; Lou, Fengliu; Li, Yahao; Buan, Marthe Emelie Melandsø; Duan, Xuezhi; Walmsley, John Charles; Sheridan, Edel; Chen, De (Journal article; Peer reviewed, 2016)The specific energy of a supercapacitor (SC) with an ionic liquid (IL)-based electrolyte is larger than that using an aqueous electrolyte owing to the wide operating voltage window provided by the IL. However, the wide-scale ... -
Boosting properties of 3D binder-free manganese oxide anodes by preformation of a solid electrolyte interphase
Zhou, Haitao; Wang, Xuehang; Sheridan, Edel; Chen, De (Journal article; Peer reviewed, 2015)Huge irreversible capacity loss prevents the successful use of metal oxide anodes in Li-ion full cells. Here, we focus on the critical prelithiation step and demonstrate the challenge of electrolyte decomposition on a ... -
Boosting the energy density of 3D dual-manganese oxides-based li-ion supercabattery by controlled mass ratio and charge injection
Zhou, Haitao; Wang, Xuehang; Sheridan, Edel; Gao, Hongquan; Du, Juan; Yang, Jianhong; Chen, De (Journal article; Peer reviewed, 2016)Supercabatteries, combining the energy of secondary batteries with the power of supercapacitors, have attracted significant attention in the energy storage research and market field. Herein, we continued our previous 3D ... -
Enhancing capacitance of supercapacitor with both organic electrolyte and ionic liquid electrolyte on a biomass-derived carbon
Wang, Xuehang; Li, Yahao; Lou, Fengliu; Buan, Marthe Emelie Melandsø; Sheridan, Edel; Chen, De (Journal article; Peer reviewed, 2017)Supercapacitor (SC) with organic electrolyte or ionic liquid (IL) electrolyte can generally store/release higher energy than that with an aqueous electrolyte, due to a larger operating voltage window of a non-aqueous ... -
Porous Carbon Prepared by Chemical Activation for High-Energy Supercapacitors in Ionic Liquid Electrolyte
Wang, Xuehang (Doctoral theses at NTNU;2016:264, Doctoral thesis, 2016)Supercapacitor (SC), a high-power, safe and long-lifetime energy storage device, has been considered as a potential candidate to replace the use of rechargeable batteries for mobile high-power application. Due to the ... -
Selective Charging Behavior in an Ionic Mixture Electrolyte- Supercapacitor System for Higher Energy and Power
Wang, Xuehang; Mehandzhiyski, Aleksandar Yordanov; Arstad, Bjørnar; Van Aken, Katherine L.; Tyler S., Mathis; Gallegos, Alejandro; Tian, Ziqi; Ren, Dingding; Sheridan, Edel; Grimes, Brian Arthur; Jiang, De-en; Wu, Jianzhong; Gogotsi, Yury; Chen, De (Journal article; Peer reviewed, 2017)Ion–ion interactions in supercapacitor (SC) electrolytes are considered to have significant influence over the charging process and therefore the overall performance of the SC system. Current strategies used to weaken ionic ... -
Thermal characterisation of anode materials for Li-ion batteries
Gullbrekken, Øystein (Master thesis, 2012)Coin cells with lithium and graphite electrodes were assembled using different combinations of graphite material and electrolyte. Specifically, three commercially available graphite materials and five electrolyte compositions ...
