  • Advanced and Emerging Negative Electrodes for Li-Ion Capacitors: Pragmatism vs. Performance 
    Lai, Samson Yuxiu; Cavallo, Carmen; Abdelhamid, Muhammad; Lou, Fengliu; Koposov, Alexey (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)
    Li-ion capacitors (LICs) are designed to achieve high power and energy densities using a carbon-based material as a positive electrode coupled with a negative electrode often adopted from Li-ion batteries. However, such ...
  • Cycling performance of silicon-carbon composite anodes enhanced through phosphate surface treatment 
    Gobena, Hana; Lai, Samson Yuxiu; Koposov, Alexey; Mæhlen, Jan Petter; Ghamouss, Fouad; Lemordant, Daniel (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    Abstract Silicon (Si)‐based anodes have long been viewed as the next promising solution to improve the performance of modern lithium‐ion batteries. However, the poor cycling stability of Si‐based anodes impedes their ...
  • Enabling Increased Delithiation Rates in Silicon-Based Anodes through Alloying with Phosphorus 
    Huld, Frederik Thorbjørn; Lai, Samson Yuxiu; Tucho, Wakshum Mekonnen; Batmaz, Rasim; Jensen, Ingvild Julie Thue; Lu, Song; Eleri, Obinna Egwu; Koposov, Alexey; Yu, Zhixin; Lou, Fengliu (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)
    The capability of battery materials to deliver not only high lithium storage capacity, but also the ability to operate at high charge/discharge rates is an essential property for development of new batteries. In the present ...
  • Morphology engineering of silicon nanoparticles for better performance in Li-ion battery anodes 
    Lai, Samson Yuxiu; Mæhlen, Jan Petter; Preston, Thomas; Skare, Marte Orderud; Nagell, Marius Uv; Ulvestad, Asbjørn; Lemordant, Daniel; Koposov, Alexey (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)
    Amorphous silicon nanoparticles were synthesized through pyrolysis of silane gas at temperatures ranging from 575 to 675 °C. According to the used temperature and silane concentration, two distinct types of particles can ...
  • Revealing Silicon’s Delithiation Behaviour through Empirical Analysis of Galvanostatic Charge–Discharge Curves 
    Huld, Frederik Thorbjørn; Mæhlen, Jan Petter; Keller, Caroline; Lai, Samson Yuxiu; Eleri, Obinna E.; Koposov, Alexey; Yu, Zhixin; Lou, FengLiu (Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)
    The galvanostatic charge–discharge (GCD) behaviour of silicon (Si) is known to depend strongly on morphology, cycling conditions and electrochemical environment. One common method for analysing GCD curves is through ...
