“…Type V non-ionic DESs, for instance, lack an ionic contribution and yet still exhibit DES characteristics. 23 We note here that the present review did not cover the use of type I and II DESs, but there are some examples reporting their application in batteries, [221][222][223] and they might represent viable alternatives. Also hydrophobic DESs have been reported which may overcome the viscosity issue associated with eutectics based on large quaternary ammonium salts and have better water-stability.…”

Deep eutectic Solvents (DESs) are an emerging class of materials showing a marked depression in melting points compared to those of the neat constituents and characterized by a number of beneficial properties. DES research currently prospers and out of the multiple current applications, the electrochemistry field is likely the most flourishing. This detailed review emphasizes recent research efforts in order to apply type III and type IV DESs and their analogues as electrolytes for rechargeable cationic batteries. The recent developments in the last decade are outlined, framing outstanding achievements and open questions, and identifying future optimisation directions to overcome the existing challenges.

The utility of carbon quantum dots (CQDs) based electrodes prepared from biomass has drawn the attention of the scientists and industrialists due to their structural diversities, tuneable physical or chemical properties, and economical, environmental, and social considerations. As the raw material for the production of CQDs is abundantly available in nature at low‐cost any technological know‐how is bound to be sustainable. These carbon quantum dots with porous structure have ideal architecture, physicochemical properties, amenability for doping with heteroatoms, good electrical conductivity thus making them very attractive for electrochemical energy storage. In this paper, application potentialities of various metal ion batteries (Li+, Na+, K+, Al2+, and Zn2+) using nanostructured carbon materials, Columbic efficiency, cyclic ability, reversible discharge capacity, current density, dimensional effects and cost considerations are brought into close focus.

“…Dai's ADIB showed a high reversibility over thousands of cycles and graphite cathodic capacities of up to 67 mAh g -1 . Those first publications have initiated the exploration of deep eutectic solvents (DESs) as Al electrolytes for ADIBs by Dai et al 22,23 , Jiao et al [24][25][26] , and others [27][28][29][30][31] . A schematic illustration of the different classes of Al electrolytes presently used in ADIBs is shown in Fig.…”

In the search for sustainable energy storage systems, aluminum dual-ion batteries have recently attracted considerable attention due to their low cost, safety, high energy density (up to 70 kWh kg −1), energy efficiency (80-90%) and long cycling life (thousands of cycles and potentially more), which are needed attributes for grid-level stationary energy storage. Overall, such batteries are composed of aluminum foil as the anode and various types of carbonaceous and organic substances as the cathode, which are immersed in an aluminum electrolyte that supports efficient and dendrite-free aluminum electroplating/stripping upon cycling. Here, we review current research pursuits and present the limitations of aluminum electrolytes for aluminum dual-ion batteries. Particular emphasis is given to the aluminum plating/stripping mechanism in aluminum electrolytes, and its contribution to the total charge storage electrolyte capacity. To this end, we survey the prospects of these stationary storage systems, emphasizing the practical hurdles of aluminum electrolytes that remain to be addressed. T he integration of intermittent renewables into the grid is directly linked to the deployment of stationary energy storage systems at the terawatt scale, enabling grid stabilization. From this perspective, in addition to conventional energy storage means, such as pumpedstorage hydroelectricity (PSH), stationary batteries will be of significant importance 1. Loosely speaking, the assessment of the battery technologies for stationary storage applications can be made by comparing their capital cost (¢ kW −1 h −1 cycle −1) to that of PSH, which is presently the predominant stationary storage system. Consequently, stationary batteries should possess an exceptional cycling stability (thousands of cycles), environmental friendliness, low CO 2 footprint, and low cost. In this framework, the exploration of batteries composed of Na 2,3 , K 4 , Mg 5,6 , and Al 7-9 as earth-abundant metals has become a primary research target in recent years. Notably, batteries that employ Al metal as an anode can harness numerous advantages, such as a high charge storage capacity of 2977 mAh g −1 of Al, its natural abundance, and safety 10-15. Furthermore, Al can be reversibly deposited and stripped in chloroaluminate ionic liquids with a high coulombic efficiency and without the formation of dendrites 16,17. In this context, a new electrochemical concept called the aluminum dual-ion battery (ADIB) has recently attracted significant attention. ADIBs have a high potential for grid-scale energy storage applications
