research, aqueous electrolytes were occasionally employed for the investigation of cathode materials instead of the conventional nonaqueous electrolytes. [9,10] It was discussed that the simplicity of an aqueous electrolyte provides a better opportunity for the fundamental studies of the process of intercalation/deintercalation of Li-ions as opposed to the nonaqueous electrolytes. For instance, although the formation of solid electrolyte interphase (SEI) is of utmost importance for the cyclability of LIB, the significant role of the electrolyte does not allow to exclusively study the electrochemical behavior of the electrode material under consideration. The current research has specifically targeted the development of ARLBs, but in practice, most of the recent papers have followed the same line of research in investigating a limited range of cathode and anode materials in the same aqueous electrolytes. [11][12][13][14][15][16][17][18][19][20][21][22][23][24][25][26][27][28] A possible reason is that the key advantage of ARLBs was low cost, and thus, the focus was limited to a few inexpensive materials (e.g., lithium salts). Aqueous electrolytes are definitely excellent choices for the fundamental studies of electrode materials, but the practical development of ARLBs needs overcoming the key obstacles rather than finding more cathode materials.In any case, aqueous electrolytes were occasionally used during the 2000s by various research groups, but there was no vivid plan for the development of ARLBs. These works have been extensively reviewed before, [29][30][31][32][33] and it is not aimed to repeat the general works on aqueous electrolytes here. During the recent years, new opportunities have been introduced, which can extend the stable potential window of aqueous electrolyte to the range of 3-4 V. Upon this advancement, aqueous electrolytes can fairly compete with the conventional nonaqueous electrolytes for the fabrication of cheaper and safer LIBs. On the other hand, novel designs such as self-healing [34] or flexible [16,35,36] ARLBs have paved the path for new practical potentials of aqueous electrolytes. The present paper specifically focuses on the recent advancements and attempts to foster the strategy of research to shed light on the pathway of this emerging area of research. Two factors are directly responsible for achieving a high energy density, the specific capacity, and the cell voltage. Since the former is not massively controlled by the electrolyte and the specific capacity of most electroactive Owing to the high voltage of lithium-ion batteries (LIBs), the dominating electrolyte is non-aqueous. The idea of an aqueous rechargeable lithium battery (ARLB) dates back to 1994, but it had attracted little attention due to the narrow stable potential window of aqueous electrolytes, which results in low energy density. However, aqueous electrolytes were employed during the 2000s for the fundamental studies of electrode materials in the absence of side reactions such as the decomposition of organic spec...

“…These mixtures are referred to in the literature as slurry or ink. The most frequent method for preparing inks or slurries involves the use of polyvinylidene fluoride (PVDF) as binder and N-methyl-2-pyrrolidone (NMP) as solvent [12,[25][26][27][28][29][30]. This solvent is expensive, toxic and flammable [12].…”

Aqueous and organic inks of carbon xerogels as models for studying the role of porosity in lithium-ion battery electrodes

The electrochemical performances of lithium-ion batteries depend to a great extent on the method used to prepare the electrodes and on the pore texture of the active material. In the present study, carbon xerogels with different pore sizes and pore volumes were synthesized by means of microwave heating. These carbonaceous materials were used to prepare lithium-ion battery anodes. Generally, electrodes are prepared by coating a slurry made of an active material, a binder and N-methyl-2-pyrrolidone as organic solvent. The disadvantage of this solvent is that it is both toxic and costly. In this work, the use of water instead of the organic solvent and water-soluble binders yielded electrodes with similar electrochemical performances making the battery assembly process more economic and environmentally friendly. The results of this study also confirm that the use of an aqueous preparation pathway does not undermine the interdependence between the electrochemical properties of the cells and the porous properties of the carbon xerogels.

“…LiMn 2 O 4 is a very common Li-ion intercalation-type cathode for both aqueous and non-aqueous batteries [1][2][3][4][5]. The aqueous rechargeable LiMn 2 O 4 battery has been developed extensively with different types of anodes [6][7][8][9][10][11][12][13][14][15][16]. Considering cost, operational safety, and environmental issues, aqueous rechargeable lithium batteries (ARLBs) are more attractive than their non-aqueous analogues [6].…”

“…Moreover, the ionic conductivity of typical aqueous electrolytes is about two orders of magnitude higher than those of non-aqueous analogues, leading to better rate capability of the aqueous-based battery [6]. In addition to the development of ARLBs conducted by several research groups [7,[9][10][11][12][13][14][15][16]], Chen's group has introduced the rechargeable hybrid aqueous battery (ReHAB), which combines an intercalation cathode (LiMn 2 O 4 , LiFePO 4 ) with a metal (first order electrode such as zinc) anode and an aqueous electrolyte containing both Li + and Zn 2+ [17][18][19][20][21][22].…”

Three major components in a cathode of aqueous rechargeable lithium batteries are the active material, the polymer binder, and the carbon conductive additive. The stability of each component in the battery is the key to long service life. To evaluate the stability of the carbon component, we introduce here a quick and direct testing method. LiMn2O4 is chosen as a typical active material for the preparation of the cathode, with polyvinylidene fluoride (PVdF), and a commercial carbon, which is chosen among Acetylene black, superP, superP-Li, Ketjen black 1, Ketjen black 2, Graphite, KS-6, splintered glassy carbon, and splintered spherical carbon. This method reveals the correlation between the electrochemical stability of a carbon and its physical and structural properties. This helps researchers choose the right carbon component for a Li-ion cathode if they want the battery to be robust, especially at near full state of charge.
