Cold Sintering as a Cost-Effective Process to Manufacture Porous Zinc Electrodes for Rechargeable Zinc-Air Batteries
Jayasayee, Kaushik; Clark, Simon; King, Cara; Dahl, Paul Inge; Tolchard, Julian R; Juel, Mari (Peer reviewed; Journal article, 2020)Zinc-air batteries (ZABs) offer a sustainable and safe pathway to low-cost energy storage. Recent research shows that thermally-sintered porous Zn electrodes with a three-dimensional network structure can enhance the ... -
Evaluation of Electrosorption Process for Phosphate and Nitrate Removal from Wastewater
Krishnamurthy, Shreenath; Jayasayee, Kaushik; Enebakk Eide, Tom-Andre; McCay, Katie; Tschentscher, Roman; Stensrød, Ruth Elisabeth; Sunding, Martin Fleissner (Peer reviewed; Journal article, 2022)The present work is dedicated to the preparation and characterization of carbon-based electrodes for the removal of phosphates and nitrate ions from wastewater by CDI method. Carbons obtained from the pyrolysis were used ... -
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. ... -
Robust nanocomposites of a-Fe2O3 and N-doped graphene oxide: Interfacial bonding and chemisorption of H2O
Polfus, Jonathan M.; Jayasayee, Kaushik (Peer reviewed; Journal article, 2019)Nanocomposites of α-Fe2O3 (hematite) and (N-doped) graphene oxide (GO) were investigated using first-principles calculations with focus on structure, chemical bonding, electronic structure and H2O adsorption. The nanocomposites ...
