    • 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 ...

    • Modelling capacity fade in silicon-graphite composite electrodes for lithium-ion batteries 

      Dhillon, Shweta; Hernández, Guiomar; Wagner, Nils Peter; Svensson, Ann Mari; Brandell, Daniel (Peer reviewed; Journal article, 2021)
      Silicon-based composite electrodes in lithium ion batteries attract increasing attention because of their high theoretical capacity. Here, numerical simulations are used to better understand the interplay between electrochemical ...

    • 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 ...

    • 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 ...
