“…An obvious cathodic peak between 0.01 and 2.0 V can be found, corresponding to reversible insertion of lithium into the carbon layers and nanopores [51]. The intensity of the above cathodic peak in the first loop is much higher than that of the rest, which may be due to the formation of the SEI, the electrolyte decomposition, and the irreversible insertion of Li + into special sites of carbon material [52]. Figure 4b shows the discharge and charge curves from the 1st to 100th cycle of the HPC anode under a current density of 100 mA g −1 in a voltage range of 0.01-3 V. The HPC anode presents the 1st discharge and charge capacities of 1062.5 and 649.2 mAh g −1 , respectively.…”

As lithium-ion battery (LIB) anode materials, porous carbons with high specific surface area are highly required because they can well accommodate huge volume expansion/contraction during cycling. In this work, hierarchically porous carbon (HPC) with high specific surface area (~1714.83 m2 g−1) is synthesized from biomass reed flowers. The material presents good cycling stability as an LIB anode, delivering an excellent reversible capacity of 581.2 mAh g−1 after cycling for 100 cycles at a current density of 100 mA g−1, and still remains a reversible capacity of 298.5 mAh g−1 after cycling for 1000 cycles even at 1000 mA g−1. The good electrochemical performance can be ascribed to the high specific surface area of the HPC network, which provides rich and fast paths for electron and ion transfer and provides large contact area and mutual interactions between the electrolyte and active materials. The work proposes a new route for the preparation of low cost carbon-based anodes and may promote the development of other porous carbon materials derived from various biomass carbon sources.

“…The distinct hysteresis loop at the pressure range of 0.5–0.95 is reflective of mesoporosity [ 49 , 62 ]. Specific to BGC-750, a slight rise at the high pressure range (0.95 < P / P 0 < 0.99) can be observed, which proves the existence of the macropores [ 63 ], whereas for AC, the platform occupying the whole pressure region of the isotherm indicates that the porosity is mainly composed of micropores [ 64 ]. These observations are in line with the SEM and TEM results.…”

“…The three peaks in O 1 s represent quinone-type groups (C=O, O-I), phenol groups/ether groups (C–OH/C–O–C, O-II) and carboxylic groups (COOH, O-III) [ 67 ]. For N 1 s , the four peaks present pyridinic-N (N-6), pyrrolic-N (N-5), quaternary-N (N-Q) and oxidized N (N-X), respectively [ 63 , 67 , 68 ]. Other BGCs exhibit identical functional group configurations (Fig.…”

“…These b values indicate that the charge storage processes in BGC cathodes are capacitive in nature occurring on the carbon surface with negligible ion diffusion action in carbon bulk, which agrees with the aforementioned observation. Meanwhile, the contribution of the capacitive charge storage was quantitatively calculated via dividing the current response into two parts (proportional to v 1/2 and v ) as following equation: i = k 1 v + k 2 v 1/2 [ 63 ]. Variables k 1 and k 2 represent the proportions of the capacitive and non-capacitive contributions.…”

Aqueous zinc-based batteries (AZBs) attract tremendous attention due to the abundant and rechargeable zinc anode. Nonetheless, the requirement of high energy and power densities raises great challenge for the cathode development. Herein we construct an aqueous zinc ion capacitor possessing an unrivaled combination of high energy and power characteristics by employing a unique dual-ion adsorption mechanism in the cathode side. Through a templating/activating co-assisted carbonization procedure, a routine protein-rich biomass transforms into defect-rich carbon with immense surface area of 3657.5 m2 g−1 and electrochemically active heteroatom content of 8.0 at%. Comprehensive characterization and DFT calculations reveal that the obtained carbon cathode exhibits capacitive charge adsorptions toward both the cations and anions, which regularly occur at the specific sites of heteroatom moieties and lattice defects upon different depths of discharge/charge. The dual-ion adsorption mechanism endows the assembled cells with maximum capacity of 257 mAh g−1 and retention of 72 mAh g−1 at ultrahigh current density of 100 A g−1 (400 C), corresponding to the outstanding energy and power of 168 Wh kg−1 and 61,700 W kg−1. Furthermore, practical battery configurations of solid-state pouch and cable-type cells display excellent reliability in electrochemistry as flexible and knittable power sources.

Carbon nanosheets (CNs) were successfully synthesized from nettle stem (NS) which is an inexpensive material with a high carbon content that is abundantly available in nature. CNs were produced using chemical (potassium hydroxide activation and acid exfoliation) and thermal treatments. Sulfuric (H2SO4), phosphoric (H3PO4) and nitric (HNO3) acid solutions were used for exfoliation. CNs exfoliated by H3PO4 have higher specific surface area (789 m2 g−1) compared to CNs exfoliated by H2SO4 (705 m2 g−1) and HNO3 (106 m2 g−1). In this work, NSCNs were found to be a potential candidate for electrode material in electrochemical capacitors. The maximum specific capacitance of the NSCNs exfoliated by H3PO4 is found to be 27.3 F g−1 at a current density of 0.05 A g−1, while the specific capacitance of NSCNs exfoliated by H2SO4 and HNO3 is 9.34 F g−1 and 1.71 F g−1, respectively. Energy density (0.06–0.95 Wh kg−1) and power density (20.9–26.7 W kg−1) of NSCNs are confirmed to be supercapacitor materials and can be applied in energy storage devices.
