“…Notably, the current response at high potential was much higher than that at low potential owing to the rational design of GLPC electrodes. The working voltage of the LIC was mostly over 3.0 V, which was higher than those of the other LICs assembled by porous carbon electrodes (with average voltages below 2.5 V), [35][36][37][38][39][40][41][42] thus resulting in high energy property. Based on the GCD curves shown in Fig.…”

Owing to the hybrid energy-storage features, Li-ion capacitors (LICs) inherit appealing properties from secondary batteries and supercapacitors, including high power density, high energy density and good cycling stability. However, incompatible kinetics between anode and cathode limit the performance improvement of the LICs. Moreover, the energy-storage mechanisms of carbon electrodes for LICs need to be further explored. Herein, we have prepared two ginkgo leaf-derived porous carbons (GLPCs) and used them as LIC electrodes. As resourceful biomass materials, ginkgo leaves have numerous O,N,S-enriched organics (e.g., flavonoids, alkaloids and thiophenes). By direct pyrolysis of the ginkgo leaves, ternary doped GLPCs are obtained without using additional dopants. The porosities, heteroatoms and defects for the GLPCs are tailored based on electrode requirements. The GLPCs obtained at 600 and 900 °C are specifically employed as the anode and cathode materials for LICs, respectively. The GLPC electrodes show good performance in half cells and their energy-storage mechanisms are interpreted by detailed ex situ and in situ experiments. DFT calculation results reveal that only specific heteroatom doping can enhance Li+ and PF6 − storage. Because of compatible electrode kinetics, the assembled LIC using the GLPC electrodes delivers high energy (118 Wh kg−1), high power (31.6 kW kg−1) and long lifespan.

“…In addition, the study found that the introduction of alumina nanofibers made the composite battery separator exhibit better porosity, liquid electrolyte affinity, and lower interfacial resistance, thereby improving the battery cycle stability. Liu et al ( Figure 13 ) [ 119 ] prepared inorganic–organic nanofiber composite separators for lithium-ion capacitors (LICs) by wet, using electrospun alumina nanofibers and polyimide nanofibers(PI) as components. Alumina nanofibers provided rapid ion transfer properties and excellent fire resistance for this composite separator, and the presence of polyimide nanofibers enhanced the heat resistance and entanglement.…”

“…Here, we present an innovative strategy in which continuous Al 2 O 3 nanofibers were manufactured by electroblown spinning (EBS) under both gas pressure and high voltage with an efficiency up to dozens of times that achievable by electrospinning, 19,20 followed by vacuum filtration to enable the formation of a 3D network structure from an aqueous Al 2 O 3 dispersion. Then, the PEO-LiTFSI solution was cast in the nanofiber interstices to form a PEO-based composite solidstate electrolyte reinforced by Al 2 O 3 nanofibrous membranes (AOM-PEO-LiTFSI).…”
