“…Typically, as a redox‐amphoteric material, graphite can be used as both the cathode and anode materials in DIBs. The resulting positive or negative charge can be compensated by the intercalation of a variety of certain anionic/cationic intercalation guests into the interlayer gaps of the graphite layers . In 1938, Rüdorff and Hofmann first reported the concept of graphite oxidation as the cathode material by electrochemical intercalation of HSO 4 − anions from an aqueous electrolyte .…”

Rechargeable dual‐ion batteries are considered to be potential candidates for applications in electrochemical energy storage devices. Ionic liquid is one of the most promising electrolytes due to its superior ionic conductivity and the wide electrochemical window. In this work, a novel dual‐graphite battery system was developed based on a pure 1‐butyl‐1‐methylpyrrolidinium bis(trifluoromethylsulfonyl) imide ionic liquid electrolyte and dual graphite electrodes. The working mechanism of the dual‐graphite battery based on a pure ionic liquid electrolyte without any metallic elements was proposed and investigated in detail. The cell delivers a reversible specific capacity of 49 mAh g−1 at a current density of 50 mA g−1, a high Coulombic efficiency of approximately 97.4 % and a fine cycling stability at high cut‐off voltage 4.6 V over 100 cycles. Moreover, the dual‐ion battery system, which is made entirely of non‐metallic elements, exhibits a high and obvious discharge voltage plateaus at about 3.7 V. These results encourage the further development of new types of futuristic rechargeable non‐metallic battery energy storage systems.

“…presented a high‐voltage electrolyte based on a fluorocarbonate solvent and additive, 1.7 M LiPF 6 in FEC–EMC (4 : 6 w/w)+5 mM HFIP (tris (hexafluoro‐iso‐propyl)phosphate), for a dual‐graphite battery, which supported the intercalation of PF 6 − at 5.2 V and demonstrated a capacity of 65 mAh g −1 with an average CE of 97.5 % . In the work of Aladinli et al., the Li/graphite cell utilizing 0.5 M NaPF 6 /PC electrolyte with 2 vol.% FEC additive exhibited substantially enhanced CEs of >98 % (Figure ) . The improved CE is owing to the preferential oxidation of FEC that established a stable SEI layer on graphite cathode and prevented the electrolytes from further degradation.…”

“…For instance, ClO 4 À would be inevitably oxidized at high potentials (> 4.6 V), which results in a lower charge cut-off potential and hence lower reversible capacity. [48,49] Both bis (trifluoromethanesulfonyl) imide (TFSI À ) and bis (fluorosulfonyl) imide (FSI À ) show low activation energies for interfacial anion transfer between the carbonate electrolyte and the graphite cathode, but they are expensive and tend to corrode Al current collectors at high potentials (> 4 V). [50][51][52] Therefore, the preferred anion used in carbonate electrolytes for DCBs is PF 6 À .…”

Dual‐carbon batteries (DCBs) are a promising candidate for smart grid applications, owing to their low cost, high power capability, and environmentally friendly benefits. As an essential component of DCBs, electrolytes not only act as a medium for ion migration during the running of the battery, but also provide active ions to be intercalated into carbon electrodes, exerting significant impacts on the electrochemical performance and safety of the DCB. In this Review, we discuss recent progress in electrolyte research for DCBs, including conventional liquid electrolytes, highly concentrated electrolytes, and gel polymer electrolytes, with a focus on their stability and compatibility with carbon electrodes. Finally, we present perspectives on the current limitations and future research directions of electrolytes for DCBs. Some recommendations for battery evaluation are also offered.

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...
