Silicon anodes for lithium-ion batteries produced from recovered kerf powders
Wagner, Nils Peter; Tron, Artur; Tolchard, Julian R; Noja, Gianluigi; Bellmann, Martin Pawel (Journal article; Peer reviewed, 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, ... -
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 ... -
A study on multilayered MXenes for rechargeable battery electrodes through surface termination control
Fagerli, Frode Håskjold (Doctoral theses at NTNU;2023:19, Doctoral thesis, 2023)In the transition from fossil fuels to renewable energy sources, the demand for rechargeable batteries is rapidly increasing. To meet this demand, a diversification of battery chemistries will be essential, due to limited ... -
Surface Treatment of Graphite for the Mitigation of Lithium Plating in Fast Charging Lithium-Ion Batteries
Bjønnes, Emilie (Master thesis, 2022)Grafittanoden har vært det foretrukne valget for bruk i litium-ionbatterier (LIB-er) siden de ble kommersialisert i 1991, på grunn av dens lave kostnad, råmaterialtilgjengelighet, relativt høye energi- og effekttetthet og ... -
Synthesis and Structural Stability Investigations of Mg and Nb Modified Ultra-High Ni Layered Oxides for Li-ion Batteries
Andersen, Siri (Master thesis, 2022)Nikkel-rike lagbygde oksider har blitt bevist å kunne oppnå veldig høy kapasitet noe som har ført til stor interesse for dem i industrien. En negativ egenskap ved disse materialene er derimot den strukturelle ustabiliteten ... -
The Effect of Tortuosity and Porosity Graded Graphite Electrodes in Lithium-Ion-Batteries During Fast Charging
Hognestad, Mari (Master thesis, 2022)I dette prosjektet ble effekten av tortuositet og elektroder med porøsitets gradient studert under hurtigladning. To grafitt pulvere med ulik morfologi ble brukt til å lage elektroder. Disse pulverne er kalt S48 og S93. ...
