Abstract:Lithium‐ion capacitors (LICs) exhibit superior power density and cyclability compared to lithium‐ion batteries. However, the low initial Coulombic efficiency (ICE) of amorphous carbon anodes (e.g., hard carbon (HC) and soft carbon (SC)) limits the energy density of LICs by underutilizing cathode capacity. Here, a solution‐based deep prelithiation strategy for carbon anodes is applied using a contact‐ion pair dominant solution, offering high energy density based on a systematic electrode balancing based on the … Show more
