“…Different from slow reaction kinetics and poor structural stability in graphite, hard carbon exhibits rapid Na + /K + transport rate and tolerates volume expansion because of rich pores and large interlayer spacing, which makes it suitable for Na + /K + storage. [97][98][99][100] It is no doubt that the development of SIBs is rapid and lots of hard carbon materials with unique structure and excellent performance have been proposed. [101] The mechanism of sodium storage in hard carbon is the focus of these researches, several mechanisms have been proposed, including "adsorption-intercalation" mechanism (Figure 5a), "intercalationadsorption" mechanism ( Figure 5b) and "intercalation-pore filling" mechanism ( Figure 5c).…”

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...

“…However, V 2 O 5 suffers from the sluggish kinetics due to the narrow interplanar spacing (4.4 Å) and poor electrical conductivity (10 −2 -10 −3 S cm −1 ) [36,37]. The interplanar spacing of layered materials is critical to the electrochemical properties of electrodes [38][39][40]. To modify the reaction kinetics of V 2 O 5 , ions or molecules have been introduced into the interlayers, such as Na + [41], K + [42], Cu 2+ [43], H 2 O [44], and PANI [45].…”

Ammonium vanadate with bronze structure (NH4V4O10) is a promising cathode material for zinc-ion batteries due to its high specific capacity and low cost. However, the extraction of $${\text{NH}}_{{4}}^{ + }$$ NH 4 + at a high voltage during charge/discharge processes leads to irreversible reaction and structure degradation. In this work, partial $${\text{NH}}_{{4}}^{ + }$$ NH 4 + ions were pre-removed from NH4V4O10 through heat treatment; NH4V4O10 nanosheets were directly grown on carbon cloth through hydrothermal method. Deficient NH4V4O10 (denoted as NVO), with enlarged interlayer spacing, facilitated fast zinc ions transport and high storage capacity and ensured the highly reversible electrochemical reaction and the good stability of layered structure. The NVO nanosheets delivered a high specific capacity of 457 mAh g−1 at a current density of 100 mA g−1 and a capacity retention of 81% over 1000 cycles at 2 A g−1. The initial Coulombic efficiency of NVO could reach up to 97% compared to 85% of NH4V4O10 and maintain almost 100% during cycling, indicating the high reaction reversibility in NVO electrode.

“…The b values of the three cathodic peaks of SnSe 2 NCs/C are calculated to be 0.65, 0.62, and 0.75, implying the diffusion and surface capacitance controlled behavior coexisted in the charge process. To further quantify the storage contribution for SnSe 2 NCs/C, the current (i) was separated at a fixed voltage (V) based on the following equation [41][42][43][44][45][46][47][48][49][50][51][52][53]:…”

Tin selenides have been attracting great attention as anode materials for the state-of-the-art rechargeable sodium-ion batteries (SIBs) due to their high theoretical capacity and low cost. However, they deliver unsatisfactory performance in practice, owing to their intrinsically low conductivity, sluggish kinetics and volume expansion during the charge-discharge process. Herein, we demonstrate the synthesis of SnSe 2 nanocrystals coupled with hierarchical porous carbon (SnSe 2 NCs/C) microspheres for boosting SIBs in terms of capacity, rate ability and durability. The unique structure of SnSe 2 NCs/C possesses several advantages, including inhibiting the agglomeration of SnSe 2 nanoparticles, relieving the volume expansion, accelerating the diffusion kinetics of electrons/ions, enhancing the contact area between the electrode and electrolyte and improving the structural stability of the composite. As a result, the as-obtained SnSe 2 NCs/C microspheres show a high reversible capacity (565 mA h g −1 after 100 cycles at 100 mA g −1), excellent rate capability, and long cycling life stability (363 mA h g −1 at 1 A g −1 after 1000 cycles), which represent the best performances among the reported SIBs based on SnSe 2-based anode materials.
