“…The compositions of the SEI layers in the ASSLBs with/without the additives were analyzed on the cycled lithium anodes by XPS (Figure ). As shown in the F 1s spectra (Figures a,b and S6a), there were two characteristic peaks of LiF (684.5 eV) and C–F (688.5 eV) in the CSE-0LiPO 2 F 2 /ASE-0LiFSI ASSLBs and CSE-5LiPO 2 F 2 /ASE-10LiFSI . The LiF in the former ASSLBs originated from the decomposition of LiTFSI, being uneven and hardly suppressing the growth of lithium dendrite, while the LiF previously generated from LiFSI additive in the latter cells was homogeneous and led to a uniform Li deposition .…”

Lithium-ion capacitors (LICs) consist of a capacitor-type cathode and a lithium-ion battery-type anode, incorporating the merits of both components. Well-known for their high energy density, superior power density, prolonged cycle life, and commendable safety attributes, LICs have attracted enormous interest in recent years. However, the construction of high-performance LIC devices faces significant constraints due to the inherent kinetic imbalances between the battery-type and the capacitor-type electrode materials and the trade-off between energy density, power density, and cycle stability. Hence, many efforts have been made to develop high-performance LICs. This review mainly focuses on the recent progresses in LICs, particularly containing the cathode and anode active materials, anode prelithiation technologies, conductive additives, and nonaqueous electrolytes. Finally, a summary and outlook are presented to highlight some future challenges for hybrid LICs.

Hybrid potassium‐ion capacitors (PICs) and potassium dual‐ion batteries (PDIBs) represent two types of potassium‐based electrochemical energy storage devices. Their differences in the microstructure of carbon cathodes enable PICs and PDIBs to possess high power and energy density, respectively. Herein, a hybrid device integrating PIC and PDIB, called as dual‐ion capacitor‐battery hybrid device (DICB), is designed by modifying the microstructure of carbon cathode, to simultaneously acquire high power and energy density. By utilizing the carbon cathode combining highly‐disordered and pseudo‐graphitic microstructures, the resultant DICB demonstrates excellent energy density (320.4 Wh kg−1) and power density (15.9 kW kg−1) with 1.5‐4.5 V. By utilizing the carbon cathode having both pseudo‐graphitic and highly‐graphitic microstructures, the corresponding DICB can achieve an elevated energy density (351.7 Wh kg−1) within a wider voltage range 1.5‐5.0 V. Experiments reveal that in the mixed microstructures of carbon cathodes, highly‐disordered part mainly exhibits capacitive contribution, the pseudo‐graphitic part provides both capacitor‐ and battery‐type energy storage behaviors, and the highly‐graphitic part offers additional capacity through ion insertion/extraction in the higher voltage region. Consequently, the carbon cathode with mixed microstructure can introduce both capacitor‐ and battery‐type energy storage behaviors in a device, thereby regulating the energy and power output characteristics of the DICB.
