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) -
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, ... -
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 ... -
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 ... -
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 ... -
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 ... -
A Single-Pot Co-Precipitation Synthesis Route for Ni-Rich Layered Oxide Materials with High Cycling Stability
Pollen, Harald Norrud; Tolchard, Julian R; Svensson, Ann Mari; Wagner, Nils Peter (Peer reviewed; Journal article, 2022)In this work we report variations of LiNi0.88Mn0.06Co0.06O2 synthesised through a single-pot oxalic acid co-precipitation route, in which all cation precursors were added in the same step. The effects of Al-doping, ...
