“…Speed mixing (15 minutes) followed by sonication (5 minutes) was repeated 3 times until a homogeneous dispersion was obtained. [22,48] To confirm the reliability of the electrode preparation process, which has already been used for lithium-air batteries, [47,49] the same procedure was used for the preparation of a LiFePO 4 (LFP) electrode (the LFP was kindly supplied by ALEEES) with a loading of 5-6 mg cm À2 . Finally, disks of 10 mm diameter were cut and dried under vacuum at 110 8C overnight ( Figure S1a).…”

A high-performance Al/graphite battery has been investigated, employing a natural graphite cathode (NG) and 1-ethyl-3methylimidazolium chloride (EMIMCl):AlCl 3 as electrolyte. The employed graphite is characterized by excellent reversibility as revealed by electrochemical tests and ex-situ XRD. The Al/ EMIMCl:AlCl 3 /NG battery showed extraordinary performance in terms of rate capability, and cycle life. The cell delivered a capacity of 110 mAh g À1 at lower current values, retaining 90 % and 60 % of the capacity employing a current of 20 A g À1 and 50 A g À1 , respectively (i. e., a complete charge-discharge cycle in 35 and 9 seconds, respectively). Furthermore, the cycling test performed using a current of 20 A g À1 revealed an extremely long calendar life of half million of cycles. The practical applicability of the investigated Al/graphite system has been ascertained; this involved estimating the energy efficiency as a function of current rate and carefully calculating the practical energy densities that can be obtained from the system.

“…The most common electrolytes for DCBs are organic carbonates and ionic liquid (IL) solvents paired with various inorganic/organic salts such as LiPF 6 , NaPF 6 , and n‐butyl pyridinium [PF 6 ] . Their concentration is usually set to be between 0.5 and 2 mol L −1 to ensure high ionic conductivity and low viscosity.…”

[26][27][28][29][30][31][32][33][34][35][36][37][38] Their concentration is usually set to be between 0.5 and 2 mol L À 1 to ensure high ionic conductivity and low viscosity. These electrolytes, however, suffer from severe decomposition on carbonaceous cathodes and/or anodes because of the superior catalytic activity of the defects in carbonaceous materials, [39][40][41] causing unsatisfactory Coulombic efficiency (CE) and inferior cycling performance of DCBs.…”

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.

“…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...
