“…In contrast to ZPC, the spectrum of BZPC had a tiny peak at a binding energy of ∼191 eV, which is a B1s peak with 1.63% atomic content, indicating successful boron doping ( Wang et al, 2018a ). Compared with the high-resolution C1s deconvolution peak of ZPC ( Supplementary Figure S4B ), BZPC has an additional fitted peak at 284.1 eV corresponding to the C–B bond ( Figure 3A ) ( Ahmad et al, 2020 ), further confirming the binding of B atoms to the carbon skeleton. In addition, the high-resolution B1s peak of BZPC was deconvoluted into three characteristic peaks ( Figure 3B ) at 188.5, 191.35, and 193.6 eV, corresponding to BC 3 , BC 2 O, and BCO 2 , respectively ( Wang et al, 2016 ; Wang et al, 2019 ; Lian et al, 2022 ).…”

“…This was consistent with the results of selected area electron diffraction (SAED, inset of Figure 2A ). Compared with pure carbon (ZPC) (( Supplementary Figure S2A ), doped boron broadened the carbon framework, expanded the average distance between graphite layers from 0.342 nm (ZPC) to 0.416 nm (BZPC) ( Wang et al, 2016 ; Ahmad et al, 2020 ), which was conducive to potassium ion insertion/extraction. Furthermore, compared with the energy dispersive X-ray spectroscopy (EDS) map of ZPC, the boron signal of BZPC was uniformly distributed throughout the carbon matrix, indicating that boron was successfully doped into the carbon skeleton ( Figure 2B and Supplementary Figure S2B ).…”

“…Supplementary Figure S3A displayed the XRD spectra of BZPC and ZPC, both materials showed amorphous carbon features with two broad characteristic diffraction peaks around 23° and 42° corresponding to the 002 and 100 planes of graphitic carbon ( Gao et al, 2019 ; Ahmad et al, 2020 ), respectively. These results were consistent with the HRTEM images.…”

“…The I D /I G values of BZPC and ZPC were 1.03 and 0.89, respectively, indicating that B doping increased the disorder in the carbon material, exposing more defect sites and providing more active sites for the adsorption and desorption of potassium ions, therefore improving capacitive storage and rate capability ( Wang et al, 2018a ; Cui et al, 2020a ). The introduction of boron primarily created more edges, defects, and vacancies in the carbon skeleton, which inhibits graphitization, resulting in an increase in carbon disorder ( Wang et al, 2019 ; Ahmad et al, 2020 ).…”

Potassium-ion batteries (KIBs) have received widespread attention as an alternative to lithium-ion batteries because of their low cost and abundance of potassium. However, the poor kinetic performance and severe volume changes during charging/discharging due to the large radius of potassium leading to low capacity and rapid decay. Therefore, development of anode materials with sufficient space and active sites for potassium ion deintercalation and desorption is necessary to ensure structural stability and good electrochemical activity. This study prepared boron-doped pine-cone carbon (BZPC) with 3D interconnected hierarchical porous in ZnCl2 molten-salt by calcination under high temperature. The hierarchical porous structure promoted the penetration of the electrolyte, improved charge-carrier diffusion, alleviated volume changes during cycling, and increased the number of micropores available for adsorbing potassium ions. In addition, due to B doping, the BZPC material possessed abundant defects and active centers, and a wide interlayer distance, which enhanced the adsorption of K ions and promoted their intercalation and diffusion. When used as the anode of a KIB, BZPC provided a high reversible capacity (223.8 mAh g−1 at 50 mA g−1), excellent rate performance, and cycling stability (115.9 mAh g−1 after 2000 cycles at 1 A g−1).

“…It is an effective strategy to solve the above problems for introducing the doping heteroatoms (S, N, P and B) into carbon materials, which will generate more active sites and abundant defects and increase the layer spacing of the material to facilitate Na + store [31–37] . Among them, nitrogen‐rich carbon materials have made outstanding achievements in energy storage.…”

Sodium‐ion hybrid capacitors (SIHCs) are considered a prospective alternative to lithium‐ion batteries (LIBs) since there are rich and available sodium reserves. Here, nitrogen‐doped carbon tubes (N‐MJ) derived from metaplexis japonica fluff are prepared by using a facile method of etching and peeling the fluff with urea to prepare a Na+ storage anode. With prominent traits in terms of structure and a high nitrogen content (11.08 %), N‐MJ exhibits exceptional Na+ storage performance with a high reversible capacity (390.9 mAh g−1 at 50 mA g−1) and excellent long‐term circulation (208.1 mAh g−1 after 2650 cycles at 1 A g−1). Systemic kinetic analysis manifests that the extraordinary performance is responsible for the large‐scale capacitance control. Furthermore, the SIHCs assembled by using N‐MJ and activated carbon (AC) presents a maximum energy density of 111.4 Wh kg−1 (at 445.8 W kg−1) and power density of 2455.2 W kg−1 (at 34.1 Wh kg−1). Notably, the developed SIHCs maintain a 100 % capacity retention rate at 1 A g−1 after 5000 cycles. Overall, our work not only provides a good choice for storage Na+ anode materials, but also supplies a feasible method for the recycling of waste biomass.

Carbon micro/nanocages have received great attention, especially in electrochemical energy‐storage systems. Herein, as a proof‐of‐concept, a solid‐state gas‐steamed metal–organic‐framework approach is designed to fabricate carbon cages with controlled openings on walls, and N, P dopants. Taking advantage of the fabricated carbon cages with large openings on their walls for enhanced kinetics of mass transport and N, P dopants within the carbon matrix for favoring chemical adsorption of Zn ions, when used as carbon cathodes for advanced aqueous Zn‐ion hybrid supercapacitors (ZHSCs), such open carbon cages (OCCs) display a wide operation voltage of 2.0 V and an enhanced capacity of 225 mAh g−1 at 0.1 A g−1. Also, they exhibit an ultralong cycling lifespan of up to 300 000 cycles with 96.5% capacity retention. Particularly, such OCCs as electrode materials lead to a soft‐pack ZHSC device, delivering a high energy density of 97 Wh kg−1 and a superb power density of 6.5 kW kg−1. Further, the device can operate in a wide temperature range from −25 to + 40 °C, covering the temperatures for practical applications in daily life.
