Hematite microdisks as an alternative anode material for lithium-ion batteries
Balasingam, Suresh Kannan; Kundu, Manab; Balamuralitharan, Balakrishnan; Kim, Hee-Je; Svensson, Ann Mari; Jayasayee, Kaushik (Journal article; Peer reviewed, 2019)In this work, hematite microdisks (500 nm to 1 μm in diameter, ∼200 nm in thickness) have been synthesized by a facile hydrothermal method which exhibited good cycling stability at a current density of 200 mA g−1 and ... -
Non-Nucleophilic Electrolyte Based on Ionic Liquid and Magnesium Bis(diisopropyl)amide for Rechargeable Magnesium-Ion Batteries
Kallidanthiyil Chellappan, Lethesh; Kvello, Jannicke Hatlø; Tolchard, Julian R; Dahl, Paul Inge; Hanetho, Sidsel Meli; Berthelot, Romain; Fiksdahl, Anne; Jayasayee, Kaushik (Peer reviewed; Journal article, 2020)A non-nucleophilic electrolyte for rechargeable Mg-ion batteries is developed by the reaction of magnesium bis(diisopropyl)amide and 1-ethyl-3-methylimidazolium tetrachloroaluminate ionic liquid in tetrahydrofuran solvent. ... -
Rational design of mixed solvent and porous graphene-supported spinel oxide electrodes for high-rate and long cycle-life Mg batteries
Wang, Lu; Shao, Yuanlong; Jiang, Bo; Fiksdahl, Anne; Jayasayee, Kaushik (Peer reviewed; Journal article, 2019)The development of Mg batteries based on the interfacial charge storage mechanism, where the capacity originates from capacitive processes and the solvent-related interfacial reactions, could efficiently circumvent the ... -
Seebeck and Peltier coefficients of hydrogen electrodes related to the PEMFC
Zefaniya, Papy (Master thesis, 2012)The coefficient of Thermoelectric power of hydrogen electrode as function of partial pressure has shownto be negative in accordance with the negative sign of state function of entropy with a deviation of almost halfits ... -
Synthesis of magnesium complexes of ionic liquids with highly coordinating anion
Kallidanthiyil Chellappan, Lethesh; Fiksdahl, Anne; Jayasayee, Kaushik; Øien-Ødegaard, Sigurd (Journal article; Peer reviewed, 2019)Magnesium(II) complexes, [Mg2+(hfac−)3][Cation+], were prepared as solids from hydrophobic hexafluoroacetylacetonate ionic liquids ([Cation+][hfac−] ILs) and Mg(Tf2N)2. 1-Butyl-3-methylimidazolium ([C4mim]), N-butylpyridinium ... -
Tailored Porosities of the Cathode Layer for Improved Polymer Electrolyte Fuel Cell Performance
Zlotorowicz, Agnieszka; Jayasayee, Kaushik; Dahl, Paul Inge; Thomassen, Magnus Skinlo; Kjelstrup, Signe (Journal article; Peer reviewed, 2015)We show experimentally for the fi rst time that the introduction of macro-pores in the nanoporous catalyst layer of a polymer electrolyte membrane fuel cell can improve its performance. We have ach- ieved a Pt utilization ...
