Enhanced activated carbon lithium-ion capacitor electrochemical stability through electrolyte dielectric optimisation
Eleri, Obinna Egwu; Pires, Julie; Huld, Frederik Thorbjørn; Lu, Song; Schweigart, Philipp; Svensson, Ann Mari; Lou, Fengliu; Yu, Zhixin (Peer reviewed; Journal article, 2023)Interactions between electrolyte constituents and active materials strongly influence the capacity, energy density, and cycling stability of energy storage devices. In this study, the role of electrolyte dielectric on the ... -
Revealing mechanisms of activated carbon capacity fade in lithium-ion capacitors
Eleri, Obinna Egwu; Huld, Frederik Thorbjørn; Pires, Julie; Tucho, Wakshum Mekonnen; Schweigart, Philipp; Svensson, Ann Mari; Lou, Fengliu; Yu, Zhixin (Peer reviewed; Journal article, 2023)The capacity fade mechanism of activated carbon (AC) electrode in Li-ion electrolyte was studied via electrochemical impedance spectroscopy (EIS) and post-mortem electrode characterizations at different stages of electrochemical ...
