Anodes for Li‑ion batteries prepared from microcrystalline silicon and enabled by binder’s chemistry and pseudo‑self‑healing
Foss, Carl Erik Lie; Stephan, Müssig; Svensson, Ann Mari; Vie, Preben Joakim Svela; Ulvestad, Asbjørn; Mæhlen, Jan Petter; Koposov, Alexey (Peer reviewed; Journal article, 2020)Silicon, while suffering from major degradation issues, has been recognized as a next promising material to replace currently used graphite in the anodes of Li-ion batteries. Several pathways to mitigate the capacity fading ... -
Carbon-Coated Industrial-Grade Silicon as Potential Anode Material in Lithium-Ion Batteries
Backer, Lasse August Dørum (Master thesis, 2021)Silisium (Si) er et lovende anodemateriale for neste generasjons litium-ione-batterier (LIB) grunnet dens evne til å reversibelt danne legeringer med høy litiumkonsentrasjon. Dette gir en ekstremt høy gravimetrisk kapasitet ... -
Silicon Nanoparticle Ensembles for Lithium-Ion Batteries Elucidated by Small-Angle Neutron Scattering
Lai, Samson Yuxiu; Knudsen, Kenneth Dahl; Sejersted, Benjamin Tjeltveit; Ulvestad, Asbjørn; Mæhlen, Jan Petter; Koposov, Alexey (Journal article; Peer reviewed, 2019)Silicon in the form of nanoparticles has attracted significant interest in the field of lithium-ion batteries due to the enormous capability of lithium intake. In the present work we demonstrate the characterization of ... -
Stability and cell viability studies of silicon nanoparticles for drug delivery applications
Johnsen, Hennie Marie (Master thesis, 2020)Denne studien har som mål å undersøke potensialet til porøse og ikke-porøse silisium nanopartikler (Si NPs), laget ved en ny syntesemetode, som medisinbærere med fokus på stabilitet og biokompatibilitet. Denne typen ... -
Stoichiometry-Controlled Reversible Lithiation Capacity in Nanostructured Silicon Nitrides Enabled by in Situ Conversion Reaction
Ulvestad, Asbjørn; Skare, Marte Orderud; Foss, Carl Erik Lie; Krogsæter, Henrik; Reichstein, Jakob; Preston, Thomas J.; Mæhlen, Jan Petter; Andersen, Hanne Flåten; Koposov, Alexey (Peer reviewed; Journal article, 2021)In modern Li-based batteries, alloying anode materials have the potential to drastically improve the volumetric and specific energy storage capacity. For the past decade silicon has been viewed as a “Holy Grail” among these ... -
Toward Atomistic Understanding of Materials with the Conversion–Alloying Mechanism in Li-Ion Batteries
Park, Heesoo; van Duin, Adri C. T.; Koposov, Alexey (Peer reviewed; Journal article, 2023)The need for practical anodes for rechargeable batteries calls for new materials with improved storage capacity and cycling stability compared to the materials of today. Materials capable of alloying with alkali metals ...
