<p></p><p>Porous carbon has attracted extensive attentions as the electrode material for various energy storage devices considering its advantages like high theoretical capacitance/capacity, high conductivity, low cost and earth abundant inherence. However, there still exists some disadvantages limiting its further applications, such as the tedious fabrication process, limited metal-ion transport kinetics and undesired structure deformation at harsh electrochemical conditions. Herein, we report a facile strategy, with calcium gluconate firstly reported as the carbon source, to fabricate ultrathin porous carbon nanosheets. <a>The as-prepared Ca-900 electrode delivers excellent K-ion storage performance including high reversible capacity (430.7 mAh g<sup>-1</sup>), superior rate capability (154.8 mAh g<sup>-1</sup> at an ultrahigh current density of 5.0 A g<sup>-1</sup>) and ultra-stable long-term cycling stability (a high capacity retention ratio of ~81.2% after 4000 cycles at 1.0 A g<sup>-1</sup>). </a>Similarly, when being applied in Zn-ion capacitors, the Ca-900 electrode also exhibits an ultra-stable cycling performance with ~90.9% capacity retention after 4000 cycles at 1.0 A g<sup>-1</sup>, illuminating the applicable potentials. Moreover, the origin of the fast and smooth metal-ion storage is also revealed by carefully designed consecutive CV measurements. Overall, considering the facile preparation strategy, unique structure, application flexibility and in-depth mechanism investigations, this work will deepen the fundamental understandings and boost the commercialization of high-efficient energy storage devices like potassium-ion/sodium-ion batteries, zinc-ion batteries/capacitors and aluminum-ion batteries.</p><br><p></p>

Abstract Development of sustainable electrochemical energy storage devices faces great challenge in exploring highly efficient and low cost electrode materials. Biomass waste derived carbonaceous materials can be used as an alternative to expensive metals in supercapacitor. However, their application limited by low performance. In this study, the combination use of persimmon waste derived carbon and transition metal nitride demonstrated strong potential for supercapacitor application. Persimmon based carbonaceous gel decorated with bimetallic-nitride (N-NiCo/PC) was firstly synthesized through a green hydrothermal method. Electrochemical properties of N-NiCo/PC as electrode in 6 M KOH electrolyte solution were evaluated by using cyclic voltammetry (CV) and charge-discharge measurements. The N-NiCo/PC exhibited 895.5 F/g specific capacitance at 1 A/g current density and maintained 91.5% capacitance retention after 900 cycles. Hence, the bimetallic nitride-based-composite catalyst is a potentially suitable material for high-performance energy storage devices. In addition, this work demonstrated a promising pathway for transforming environmental waste into sustainable energy conversion materials.

Background: As an emerging carbon nanomaterial, graphene quantum dots (GQDs) have shown great potential application in new energy storage devices due to their unique small size effect and abundant edge active sites. This work introduces the main synthesis strategies of GQDs, which includes top-down and bottom-up methods; the application examples of GQDs and GQDs-based composites in energy storage are reviewed, and more, the unique advantages of GQDs are used in supercapacitors, Lithium-ion batteries (LIBs) and Lithium-sulfur batteries (Li–S batteries) are highlighted. The problems and development prospects in this growing area are also discussed. Method: We conducted a detailed search of “the application of GQDs in energy storage devices” in the published papers and the public patents based on Web of Science database in the period from 2014 to 2020. The corresponding literature was carefully evaluated and analyzed. Results: Sixty papers and twenty-eight recent patents were included in this mini-review. The significant advances in the recent years are summarized with comparative and balanced discussion. Thanks to the unique properties of large specific surface area, high conductivity and abundant active sites, GQDs have unparalleled potential application for new energy storage, especially improving the specific capacity and cycle stability of supercapacitors, LIBs and Li-S batteries. Conclusion: The findings of this mini-review confirm the importance of GQDs, show the enhanced electrochemical performance in supercapacitors, LIBs and Li-S batteries, and also provide a helpful guide to design and fabricate highefficiency electrode materials.

Abstract Biomass-activated carbon materials are promising electrode materials for lithium-ion hybrid capacitors (LiCs) because of their natural hierarchical pore structure. The efficient utilization of structural pores in activated carbon is very important for their electrochemical performance. Herein, porous biomass-activated carbon (PAC) with large specific surface area was prepared using a one-step activation method with biomass waste as the carbon source and ZnCl2 as the activator. To further improve its pore structure utilization efficiency, the PAC was doped with nitrogen using urea as the nitrogen source. The experimental results confirmed that PAC-1 with a high nitrogen doping level of 4.66% exhibited the most efficient pore utilization among all the samples investigated in this study. PAC-1 exhibited 92% capacity retention after 8000 cycles, showing good cycling stability. Then, to maximize the utilization of high-efficiency energy storage devices, LiNi0.8Co0.15Al0.05O2 (NCA), a promising cathode material for lithium-ion batteries with high specific capacity, was compounded with PAC-1 in different ratios to obtain NCA@PC composites. The NCA@PC-9 composite exhibited excellent capacitance in LiCs and an energy density of 210.9 Wh kg-1 at a high power density of 13.3 kW kg-1. These results provide guidelines for the design of high-performance and low-cost energy storage devices.
