“…Besides, part of the pores cannot be utilized, resulting in an insufficient effective surface area, so the actual capacity of AC is low [73–74] . Heteroatoms doping is an effective way to enhance the performance of AC by increasing the electrical conductivity and providing additional active sites [75] . A suitable biomass precursor material (corncob) was selected by Li et al [71] .…”

“…[73][74] Heteroatoms doping is an effective way to enhance the performance of AC by increasing the electrical conductivity and providing additional active sites. [75] A suitable biomass precursor material (corncob) was selected by Li et al [71] to in-situ synthesize a nitrogen-doped ACs (NACs) with a controllable pore structure. The N-doping can not only increase the electronic conductivity but also improve the capacity of AC via introducing the pseudocapacitance.…”

Lithium‐ion capacitors (LICs) combining of lithium‐ion batteries (LIBs) and supercapacitors (SCs) with improved performance bridge the gap between these two devices, and have attracted huge attention in the field of high‐efficiency electrochemical energy storage. The behavior of electrode materials is essential for the realization of high energy and high output LICs devices. As the most widely utilized electrodes, carbon materials demonstrated their ability in LICs with fast charge storage and long life‐span. Here, an overview of carbon materials for advanced LICs applications is given. The advantages and shortcomings of carbon materials as electrodes are systematically analyzed with the purpose of disclosing their influence on LICs devices. In light of this analysis, the critical aspects are discussed, which should be dealt with in the future for the realization of desires high‐performance LICs devices.

“…Benefiting from the diversity of composition and structure of biomass, their derived PCs with developed pore structures have high potential as electrode materials for supercapacitors (Huang et al, 2017;Yang et al, 2019;Zhao et al, 2019;Khan et al, 2020;Qian et al, 2020;Liang et al, 2021). Generally, to prepare high-performance PCs from selected biomass, some measures are taken to optimize their microstructures during the preparation process (Xu et al, 2017;He et al, 2019;Li et al, 2020b;Lin et al, 2020;Luo et al, 2020;Sun et al, 2020;Wu et al, 2020a;Xie et al, 2020a). Although those previous measures can improve the electrochemical properties, they may also show some adverse effects.…”

This study presents a novel method to improve the electrochemical performance of porous carbons (PCs) by simply adjusting the elemental composition of their precursors with nitrogen-rich materials as additives. Nitrogen-modified enteromorpha prolifera–based (EP-based) PCs are prepared from EP and urea (or melamine). Overall, compared with the control PC without nitrogen modification, their pore structures and surface chemical properties present similar improvement. When used in supercapacitors, their specific capacitances increase by approximately 22% due to their significant development of mesopores at 2.5–7.0 nm, which increases the effective surface areas. With an appropriate amount of nitrogen-containing or oxygen-containing functional groups maintaining surface wettability, the notable increase of graphitized N improves their conductivity. Due to the higher graphitization degrees, their resistances are reduced. With more mesopores transporting ions, they exhibit excellent high-rate capacitive performance. Moreover, they show remarkable long cycle performance with the specific capacitance retention of larger than 92% after 10,000 cycles.
