Risinggård, Helene Kjær; Cooil, Simon Phillip; Mazzola, Federico; Hu, Di; Kjærvik, Marit; Østli, Elise Ramleth; Patil, Nilesh; Preobrajenski, Alexei; Evans, Andrew; Breiby, Dag Werner; Trinh, Thuat; Wells, Justin (Journal article; Peer reviewed, 2018) -
Limitations of Ultrathin Al2O3 Coatings on LNMO Cathodes
Østli, Elise Ramleth; Tesfamhret, Yonas; Wenner, Sigurd; Lacey, Matthew J.; Brandell, Daniel; Svensson, Ann Mari; Selbach, Sverre Magnus; Wagner, Nils P. (Peer reviewed; Journal article, 2021)This study demonstrates the application of Al2O3 coatings for the high-voltage cathode material LiNi0.5–xMn1.5+xO4−δ (LNMO) by atomic layer deposition. The ultrathin and uniform coatings (0.6–1.7 nm) were deposited on LNMO ... -
On the Durability of Protective Titania Coatings on High-Voltage Spinel Cathodes
Østli, Elise Ramleth; Ebadi, Mahsa; Tesfamhret, Yonas; Mahmoodinia, Mehdi; Lacey, Matthew; Brandell, Daniel; Svensson, Ann Mari; Selbach, Sverre Magnus; Wagner, Nils Peter (Peer reviewed; Journal article, 2022)TiO2-coating of LiNi0.5-xMn1.5+xO4 (LNMO) by atomic layer deposition (ALD) has been studied as a strategy to stabilize the cathode/electrolyte interface and mitigate transition metal (TM) ion dissolution. The TiO2 coatings ... -
Optimization of chemical composition of novel manganite oxides for oxygen permeable membranes
Østli, Elise Ramleth (Master thesis, 2015)Every year, millions of tons of high purity oxygen are produced mainly by cryogenic distillation. Since this process is energetically demanding, there is a need for more energy efficient technologies, and the use of oxygen ... -
Oxygen Absorption in Nanocrystalline h-RMnO<inf>3</inf> (R = Y, Ho, Dy) and the Effect of Ti Donor Doping
Danmo, Frida Hemstad; Williamson, Benjamin Albert Dobson; Småbråten, Didrik Rene; Gaukås, Nikolai Helth; Østli, Elise Ramleth; Grande, Tor; Glaum, Julia; Selbach, Sverre Magnus (Journal article; Peer reviewed, 2023) -
Stabilizing strategies for the high‐voltage cathode material LiNi0.5‐xMn1.5+xO4 (LNMO)
Østli, Elise Ramleth (Doctoral theses at NTNU;2022:133, Doctoral thesis, 2022)In order to reduce the amount of greenhouse gasses and stop global warming, the transition to a renewable energy-based society needs to be accelerated. The production of energy-dense and high-performing batteries is a key ... -
Stabilizing the Cathode Interphase of LNMO using an Ionic-liquid based Electrolyte
Østli, Elise Ramleth; Mathew, Alma; Tolchard, Julian R; Brandell, Daniel; Svensson, Ann Mari; Selbach, Sverre Magnus; Wagner, Nils Peter (Peer reviewed; Journal article, 2023)The ionic liquid (IL)-based electrolyte comprising 1.2 M lithium bis(fluorosulfonyl)imide (LiFSI) in N-propyl-N-methylpyrrolidinium bis(fluorosulfonyl)imide (PYR13FSI) (ILE) has been evaluated as a suitable system for the ...
