Interphase Engineering of LiNi0.88Mn0.06Co0.06O2 Cathodes Using Octadecyl Phosphonic Acid Coupling Agents
Pollen, Harald Norrud; Nylund, Inger-Emma; Dahl, Øystein; Svensson, Ann Mari; Brandell, Daniel; Younesi, Reza; Tolchard, Julian R; Wagner, Nils Peter (Peer reviewed; Journal article, 2023)Ni-rich layered oxides are proven high-energy cathode materials for Li-ion batteries, but their characteristic short cycle life remains a challenge for implementation on a wider scale. The surface reactivity of Ni-rich ... -
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 ...
