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 ... -
Improved cyclability of Nickel-rich layered oxides
Wagner, Nils Peter; Tolchard, Julian R; Tron, Artur; Pollen, Harald Norrud; Gaertner, Heiko; Vullum, Per Erik (Peer reviewed; Journal article, 2020)This study compares the physico- and electro- chemical properties of LiNi0.8Mn0.10Co0.1O2 (NMC811) and LiNi0.83Mn0.06Co0.09Al0.1O2 (NMCA) prepared by an oxalic acid co-precipitation. Deposition of a SiO2 surface coating ... -
Improved electrochemical performance and solid electrolyte interphase properties of electrolytes based on lithium bis(fluorosulfonyl)imide for high content silicon anodes
Asheim, Karina; Vullum, Per Erik; Wagner, Nils Peter; Andersen, Hanne Flåten; Mæhlen, Jan Petter; Svensson, Ann Mari (Peer reviewed; Journal article, 2022)Electrodes containing 60 wt% micron-sized silicon were investigated with electrolytes containing carbonate solvents and either LiPF6 or lithium bis(fluorosulfonyl)imide (LiFSI) salt. The electrodes showed improved performance, ... -
Performance and failure analysis of full cell lithium ion battery with LiNi0.8Co0.15Al0.05O2 and silicon electrodes
Wagner, Nils Peter; Asheim, Karina; Vullum-Bruer, Fride; Svensson, Ann Mari (Journal article; Peer reviewed, 2019)The influence of the lithium inventory on the performance and degradation mechanism of NCA||Si cells operating at a third of the theoretical silicon capacity is analysed. The lithium inventory was increased by electrochemical ... -
Silica from diatom frustules as anode material for Li-ion batteries
Norberg, Andreas Nicolai; Wagner, Nils Peter; Kaland, Henning; Vullum-Bruer, Fride; Svensson, Ann Mari (Journal article; Peer reviewed, 2019)In spite of its insulating nature, SiO2 may be utilized as active anode material for Li-ion batteries. Synthetic SiO2 will typically require sophisticated synthesis and/or activation procedures in order to obtain a ... -
Silicon anodes for lithium-ion batteries produced from recovered kerf powders
Wagner, Nils Peter; Tron, Artur; Tolchard, Julian R; Noja, Gianluigi; Bellmann, Martin Pawel (Peer reviewed; Journal article, 2019)Silicon kerf waste from a photovoltaic silicon production process is assessed as an anode material for application as a lithium ion battery anode. In contrast to previous studies, the Si-kerf is used as-produced, with no ...
