Journal ArticleDOI
Outstanding performance of activated graphene based supercapacitors in ionic liquid electrolyte from −50 to 80 °C
Wan-Yu Tsai,Rongying Lin,Shanthi Murali,Lili Zhang,John K. McDonough,Rodney S. Ruoff,Pierre-Louis Taberna,Yury Gogotsi,Patrice Simon,Patrice Simon +9 more
TL;DR: In this paper, a carbon-ionic liquid system with high capacitance of up to 180 F/g and wide electrochemical window (up to 3.5 V) over a wide temperature range from −50 °C to 80 °C.
Journal ArticleDOI
In situ NMR and electrochemical quartz crystal microbalance techniques reveal the structure of the electrical double layer in supercapacitors
John M. Griffin,Alexander C. Forse,Wan-Yu Tsai,Pierre-Louis Taberna,Patrice Simon,Clare P. Grey +5 more
TL;DR: In situ NMR is used to directly quantify the populations of anionic and cationic species within a working microporous carbon supercapacitor electrode and shows that charge storage mechanisms are different for positively and negatively polarized electrodes for the electrolyte tetraethylphosphonium tetrafluoroborate in acetonitrile.
Journal ArticleDOI
Electrochemical Quartz Crystal Microbalance (EQCM) Study of Ion Dynamics in Nanoporous Carbons
TL;DR: Electrochemical quartz crystal microbalance and cyclic voltammetry measurements were used to characterize ion adsorption in carbide-derived carbon (CDC) with two different average pore sizes, suggesting that EMI(+) cation owns higher mobility than TFSI(-) anion in these electrolytes.
Journal ArticleDOI
Graphene-like carbide derived carbon for high-power supercapacitors
Pengcheng Gao,Pengcheng Gao,Wan-Yu Tsai,Wan-Yu Tsai,Barbara Daffos,Barbara Daffos,Pierre-Louis Taberna,Pierre-Louis Taberna,Carlos R. Perez,Yury Gogotsi,Patrice Simon,Patrice Simon,Frédéric Favier,Frédéric Favier +13 more
TL;DR: In this article, two graphene-like carbide derived carbons (CDC-Gs) were produced by chlorination of SiC nanosheets obtained by magnesio-thermal reduction at moderate temperature of silica/graphene oxide nanocomposites.
Journal ArticleDOI
Tracking ion intercalation into layered Ti3C2 MXene films across length scales
Qiang Gao,Weiwei Sun,Weiwei Sun,Poorandokht Ilani-Kashkouli,Alexander Tselev,Paul R. C. Kent,Nadine Kabengi,Michael Naguib,Mohamed Alhabeb,Wan-Yu Tsai,Arthur P. Baddorf,Jingsong Huang,Stephen Jesse,Yury Gogotsi,Nina Balke +14 more
TL;DR: In this article, the authors report a highly integrated study with multiscale theory/modelling and experiments to track the intercalation of aqueous Li+, Na+, K+, Cs+, and Mg2+ ions into Ti3C2 MXene.
