“…Therefore, researchers desire to explore cathode materials with outstanding energy density, which undoubtedly relies on the material breakthroughs. [145][146][147][148][149][150][151] In the last few years, Ni-rich cathodes bring a huge prospect due to high discharging capacity and mass energy density, which is much higher than those of conventional positive materials (LiCoO 2 , LiFePO 4 , etc.). Although Ni-rich cathode materials exhibit an appealing advantage in EV market, it still undergoes unnecessary weaknesses such as inherent volume stress, cathode-electrolyte interface side reaction upon Li + insertion/extraction process.…”

High-capacity layered oxide Ni-rich cathodes are attractive to enhance the driving-range of electric vehicles because of its preferential costs. Nevertheless, in Ni-rich cathodes, there are still many issues such as microcracks generation along grain boundaries and interface side reaction between active substance and electrolyte, resulting in the rapidly deterioration of electrochemical property. Herein, improving the performance of Ni-based cathodes by structural regulation is summarized. The remaining challenges and outlook are discussed as well.

“…Carbon-based materials have different structures (graphite, graphene, hard carbon and soft carbon) and varied morphologies, which have crucial influence on ions storage mechanism. [45,46] Generally, there are three ions storage modes (Figure 2), including i) intercalation/deintercalation into/from interlayers (intercalation/deintercalation mechanism), ii) adsorption/desorption on heteroatom, edges, and defects (adsorption/desorption mechanism), iii) filling in pores (pore-filling mechanism). The intercalation mechanism can be explained as follows: Na + /K + intercalate/deintercalate into/from interlayers of carbon materials during charging/discharging process, and ions storage capacity depends on ionic radius, interlayers structure and the thermodynamic stability of Na/K-compounds.…”

distribution make it difficult to meet the demand of large-scale energy storage device with low cost and high performance. [1,2] Sodium-ion batteries (SIBs) and potassium-ion batteries (PIBs), as "post Li-ion batteries," share similar operation principles and battery device to LIBs. [3-8] In recent years, they have drawn great attention due to obvious advantages such as high sodium/potassium abundance, even distribution and low cost, which are ideal candidates for high-performance secondary batteries in large-scale storage systems. With the continuous development of clean energy technology (including wind energy, solar energy, biomass energy, geotherm energy and water energy) and increasing proportion of clean power generation in the total power generation (the installed capacity of wind energy and solar energy may reach 7059 GW accounting for 49.21% in 2040), smart management of intermittent electricity is increasingly important. [9,10] The generated intermittent electricity needs to be regulated by a smart grid, which can be stored in high-performance SIBs/PIBs during low demand periods and released during peak demand periods, such as electricity supply of slow electric vehicles, residences, manufactories and remote area (Figure 1). [11-13] In some remote mountainous areas, there is no electricity transmission line and therefore SIBs/PIBs energy storage system can provide a continuous electricity supply as a power source. When electricity power is in short supply or out of power, SIBs/PIBs energy storage systems can provide considerable power to keep manufactory running or to power residences. Considering obvious advantages of carbon-based materials, such as abundant sources, low cost and chemical inertness, they show enormous potential as anode materials of SIBs and PIBs. [14-17] Carbon-based materials have different structures (graphite, graphene, hard carbon and soft carbon) and morphologies (0D, 1D, 2D, and 3D, here D represents dimension), [15,18-21] which makes it possible to control these factors of carbon-based materials to meet the demand of highly efficient Na + /K + storage. Graphite delivers two different Na + /K + storage behaviors with theoretical capacities of 35 mAh g −1 (Na + intercalation) and 279 mAh g −1 (K + intercalation), and the high theoretical capacity indicates that graphite is a potential candidate for PIBs. [22,23] Due to high specific surface area and abundant defects, graphene materials (except for pristine single-layered As novel "post lithium-ion batteries," sodium-ion batteries/potassium-ion batteries (SIBs/PIBs) are emerging and show bright prospect in large-scale energy storage applications due to abundant Na/K resources. Further benefits of this technology include, its low cost, chemical inertness and safety. Extensive research findings have demonstrated that carbon-based materials are promising candidates for both SIBs and PIBs. Although the two alkali-ion batteries have similar internal components and electrochemical reaction mechanisms, in carbon-based materials the stora...

“…In contrast, the intercalation potentials of Na ion for carbon anode are ≈0.05 V versus Na + /Na in sodium‐ion capacitors (SICs), resulting in a lower possibility of metal plating in PICs during the charging processes as compared to SICs, which is beneficial for improving safety in terms of operation. [ 8 ] The research on sulfur induced carbon materials in potassium ion hybrid capacitors started in 2019. A reliable method for manufacturing 3D porous carbon nanosheets co‐doped with sulfur and nitrogen elements was reported by Wen et al., which can balance the kinetic mismatch between battery‐type anodes and capacitor‐type cathodes.…”

Potassium ion capacitors (PICs) have the potential to combine the advantages of capacitors and batteries, making them promising energy storage substitutes for existing systems. Biomass‐based‐electrodes are very promising materials for potassium storage, however, at present, the acquisition of biomass‐based‐electrodes is mainly dependent on high temperature calcination, which makes the efficient utilization of biomass materials quite challenging. Herein, in accordance with ex‐situ 13C NMR and Raman, a universally directional selection strategy of biomass precursors through an advanced pre‐diagnosis method for calcination intermediates and a sulfur engineering strategy are initially proposed, proving that the carbon materials derived from precursors with fewer aliphatic chains and more aromatic carbons show a higher yield and can be have more K ions inserted. In addition, the evolution mechanism of in‐plane/interlayered CS bonds is thoroughly evaluated. Notably, PICs assembled by such carbon materials as the battery‐type anode, deliver a high energy density of 151 Wh kg‐1 and an ultrahigh power output of 10 kW kg‐1, closing to state‐of‐the‐art values for PICs. This breakthrough opens up a new avenue for targeted design of biomass materials and offers in‐depth insights into the evolution of S‐C bonds, promoting the energy/power density of PICs devices to a higher level.
