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 (Peer reviewed; Journal article, 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 ... -
Enabling long cycle life lithium-ion capacitors through electrode-electrolyte interface optimization
Eleri, Obinna Egwu (PhD thesis UiS;749, Doctoral thesis, 2024)Electrode-electrolyte interfaces in electrochemical cells represent critical boundaries between the electrode and electrolyte where most charge transfer or storage processes are initiated. Accordingly, the interface ... -
Lithium-Ion Capacitors: A Review of Strategies toward Enhancing the Performance of the Activated Carbon Cathode
Eleri, Obinna Egwu; Lou, Fengliu; Yu, Zhixin (Peer reviewed; Journal article, 2023)Lithium-ion capacitors (LiC) are promising hybrid devices bridging the gap between batteries and supercapacitors by offering simultaneous high specific power and specific energy. However, an indispensable critical component ... -
