“…Furthermore, Figure e shows the long‐term cycling stability of the MoS 2 /C‐G DIB at 2 C for 200 cycles with MoS 2 ‐G DIB as contrast. The discharge capacity remained stable with a capacity of 55 mA h g −1 after 200 cycles and 85% capacity retention, demonstrating good cycling performance of the MoS 2 /C‐G DIB, which is superior than most reported DIBs based on sodium‐ion electrolytes . The coulombic efficiency also kept at around 90% during 200 cycles apart from the first several cycles.…”

“…Sodium‐ion batteries (SIBs) have attracted more and more attention in the past decades owing to the merits of low cost and large earth abundance . However, sodium‐ion based DIBs were rarely investigated due to the larger size of Na + (1.4 times larger than Li + ), leading to failure of Na + intercalation/deintercalation into/from graphite anode. Therefore, designing appropriate anode materials plays an important role on developing high‐performance Na‐DIBs.…”

The dual-ion battery (DIB) system has attracted great attention owing to its merits of low cost, high energy, and environmental friendliness. However, the DIBs based on sodium-ion electrolytes are seldom reported due to the lack of appropriate anode materials for reversible Na insertion/extraction. Herein, a new sodium-ion based DIB named as MoS /C-G DIB using penne-like MoS /C nanotube as anode and expanded graphite as cathode is constructed and optimized for the first time. The hierarchical MoS /C nanotube provides expanded (002) interlayer spacing of 2H-MoS , which facilitates fast Na insertion/extraction reaction kinetics, thus contributing to improved DIB performance. The MoS /C-G DIB delivers a reversible capacity of 65 mA h g at 2 C in the voltage window of 1.0-4.0 V, with good cycling performance for 200 cycles and 85% capacity retention, indicating the feasibility of potential applications for sodium-ion based DIBs.

“…It is noteworthy that the state-of-the-art positive electrode materials based on sodium storage can deliver capacity values generally less than 150 mAh g −1 in potential ranges lower than 4 V versus Na/Na + . [28,29] Thus, the excellence of positive graphite electrodes will become more competitive in sodium-based DIBs.For DIBs, in contrast with the increased number of reports about anion intercalation within graphite, [30][31][32] the investigations of anodes are insufficient. In theory, anode active materials with distinguished Na + storage capacities in the low potential range can match the performance of positive graphite electrodes.…”

electrodes. [18][19][20][21][22][23][24] Among the large family of cations, lithium acts as the lightest charge carrier in nonaqueous electrolyte systems. However, lithium has to face its unfortunate fate of being a limited resource in the world. Hence, sodium has received increased attention as an alternative choice mainly because of its abundance and its similar physical and chemical properties to lithium. [25][26][27] Therefore, the application of a Na + -based organic electrolyte may be a valuable strategy for the development of DIBs in the future. It is noteworthy that the state-of-the-art positive electrode materials based on sodium storage can deliver capacity values generally less than 150 mAh g −1 in potential ranges lower than 4 V versus Na/Na + . [28,29] Thus, the excellence of positive graphite electrodes will become more competitive in sodium-based DIBs.For DIBs, in contrast with the increased number of reports about anion intercalation within graphite, [30][31][32] the investigations of anodes are insufficient. In theory, anode active materials with distinguished Na + storage capacities in the low potential range can match the performance of positive graphite electrodes. Carbon materials should be a promising candidate for this task considering the safety of the devices they are utilized in, the availability of raw materials, and other factors. [33] Lu and co-workers have reported that soft carbon is a highperformance anode material for sodium-based DIBs. [34] Based on the above, we predicted that hard carbon and graphite will also become an appropriate couple. Nevertheless, researchers are plagued by the high production cost and complex synthesis procedures for synthesizing hard carbon. [35] For the sake of tackling this issue, employing biomass resources to synthesize carbon materials is an available and convenient strategy. [36][37][38][39][40] Biomass materials can exhibit multilevel, multidimensional, and hierarchical porous structures, which can be reserved in the derived carbons and are favorable for the penetration of electrolytes and ion diffusion. [41] During synthesis, they can be used as their own templates, which solves many problems (e.g., the complicated processes, long periods, expensive raw materials, and pollution involved using other materials) caused by adopting artificial templates. [42][43][44] In addition, natural biomaterials contain heteroatoms, such as nitrogen, boron, and phosphorous, that can provide extra active sites for Na + storage. In this paper, we synthesized hard carbon by simply calcining pine needles without activation ( Figure S1, Supporting information). Dried pine needles contain crude protein, fat, fiber, and various sugars (glucose, fructose, galactose, and sucrose), [45] which are all carbon sources. Moreover, pine needles are slender. The Pine needles are used as the precursor material to prepare hard carbon. Scanning electron microscopy, X-ray diffraction, and N 2 adsorption-desorption tests are carried out to characterize the surface, crystal, and pore...

“…To achieve better cell performances, two major types of electrolytes used for DIBs are either highly concentrated organic electrolytes or ionic liquid electrolytes . Recently, different DIB chemistries based on sodium, potassium, aluminum, zinc, or calcium were developed. Except for graphite‐based cathode materials, various anion‐hosting cathodes have been exploited containing metal–organic frameworks, aromatic amine, polytriphenylamine, thianthrene, and coronene .…”

A Dual‐Ion Battery with a Ferric Ferricyanide Anode Enabling Reversible Na⁺ Intercalation

Dual‐ion batteries have been developed as a promising technology in recent years, but their high self‐discharge rate leading to low coulombic efficiency (CE) limits their practical applications. This work provides a deft strategy to circumvent this issue by using FeFe(CN)6 as the anode material for hosting Na+ cations, in combination with a graphite cathode for accommodating the bis(trifluoromethanesulfonyl)imide anions (TFSI−). The relatively high bonding force between FeFe(CN)6 and Na+ can hinder self‐extraction of ions from the electrodes, thereby decreasing the self‐discharge rate. The FeFe(CN)6 nanospheres, synthesized by a facile solution reaction method, are well crystallized and dispersed. Na+ insertion into the FeFe(CN)6 cube is determined by cyclic voltammetry (CV), galvanostatic charge–discharge, and X‐ray diffraction tests, suggesting a reversible process. Under a current of 0.05 mA cm−2 the batteries present an acceptable discharge plateau within 1.5–0.7 V and a well‐defined capacity of 75.0 mAh g−1, with a high CE above 98.5% (±0.1%); under 0.2 mA cm−2, cells display a high cyclability of 83.0% capacity retention for 100 cycles, with an excellent CE exceeding 99.6% (±0.1%). Moreover, the batteries exhibit a low self‐discharge rate with a resting capacity decay of 0.32% h−1, outperforming many of the reported dual‐ion cells.
