Are MXenes Suitable as Cathode Material for Rechargeable Mg Batteries?
Kaland, Henning; Hadler-Jacobsen, Jacob; Fagerli, Frode Håskjold; Wagner, Nils Peter; Wang, Zhaohui; Selbach, Sverre Magnus; Vullum-Bruer, Fride; Wiik, Kjell; Schnell, Sondre Kvalvåg (Peer reviewed; Journal article, 2020)MXenes, a type of two-dimensional transition metal carbide/nitride, have received significant attention for electrochemical storage applications. With substantial capacities predicted for Mg ions, MXenes have been considered ... -
Bulk substitution of F-terminations from Ti3C2Tx MXene by cation pillaring and gas hydrolysation
Fagerli, Frode Håskjold; Vullum, Per Erik; Grande, Tor; Wang, Zhaohui; Selbach, Sverre Magnus; Wiik, Kjell; Wagner, Nils Peter (Journal article, 2023)Applications of 2D MXenes are limited by the difficulty of controlling bulk termination groups after the initial HF etching step without forming surface oxides. Here, we report on gas hydrolysation using a continuous flow ... -
Dipentamethylene thiuram tetrasulfide-based cathodes for rechargeable magnesium batteries
Kaland, Henning; Hadler-Jacobsen, Jacob; Fagerli, Frode Håskjold; Wagner, Nils Peter; Schnell, Sondre Kvalvåg; Wiik, Kjell (Peer reviewed; Journal article, 2020)Rechargeable Mg batteries (RMBs) represent a possible route for low-cost energy storage applications, but they are lacking a satisfactory cathode material. Conventional sulfur (S8) cathodes have shown promise, yet they ... -
Exploring V2C MXene as a New Cathode Material for Rechargeable Magnesium Batteries
Fagerli, Frode Håskjold (Master thesis, 2018)Rechargeable magnesium batteries (RMBs) is a promising technology to compete with state-of-the art lithium-ion batteries, due to the possible improvements in safety, abundance of materials and energy density. However, one ... -
Exploring V2C MXene as Cathode Constituent for Rechargeable Magnesium Batteries
Boge, Lars-Arne (Master thesis, 2019)Oppladbare magnesiumbatterier er spådd å kunne utkonkurrere moderne Li-ion-batterier når det kommer til volumetrisk kapasitet, sikkerhet, pris og skaleringspotensiale. Hovedutfordringene som står i veien for utviklingen ... -
Performance Study of MXene/Carbon Nanotube Composites for Current Collector- and Binder-Free Mg-S Batteries
Kaland, Henning; Fagerli, Frode Håskjold; Hadler-Jacobsen, Jacob; Zhao-Karger, Zhirong; Fichtner, Maximilian; Wiik, Kjell; Wagner, Nils Peter (Peer reviewed; Journal article, 2021)The realization of sustainable and cheap Mg-S batteries depends on significant improvements in cycling stability. Building on the immense research on cathode optimization from Li-S batteries, for the first time a beneficial ... -
Removing fluoride-terminations from multilayered V2CTx MXene by gas hydrolyzation
Fagerli, Frode Håskjold; Wang, Zhaohui; Grande, Tor; Kaland, Henning; Selbach, Sverre Magnus; Wagner, Nils Peter; Wiik, Kjell (Peer reviewed; Journal article, 2022)Two-dimensional MXenes have shown great promise for many different applications, but in order to fully utilize their potential, control of their termination groups is essential. Here we demonstrate hydrolyzation with a ... -
Stacking Sequence, Interlayer Bonding, Termination Group Stability and Li/Na/Mg Diffusion in MXenes
Hadler-Jacobsen, Jacob; Fagerli, Frode Håskjold; Kaland, Henning; Schnell, Sondre KvalvÃ¥g (Peer reviewed; Journal article, 2021)A versatile group of 2D carbide materials from the past decade, MXenes, have attracted attention for their rich chemistry and wide range of properties. The perhaps best known MXene, namely, Ti3C2Tx, has been observed to ... -
A study on multilayered MXenes for rechargeable battery electrodes through surface termination control
Fagerli, Frode Håskjold (Doctoral theses at NTNU;2023:19, Doctoral thesis, 2023)In the transition from fossil fuels to renewable energy sources, the demand for rechargeable batteries is rapidly increasing. To meet this demand, a diversification of battery chemistries will be essential, due to limited ...
