“…In order to circumvent the problems accompanied by a divided cell setup, the Ackermann group introduces an unprecedented, user-friendly undivided cell arrangement for performing rhoda- 65 and ruthena-electro-catalysed 66 C-H/C-H activation and C-H/O-H annulation reactions respectively. Subsequently, other 4d and 5d metals including ruthenium, 66-70 rhodium [71][72][73][74][75] and iridium [76][77][78] were explored for electrochemical C-H activations.…”

“…[10] Significant recent impetus was gained by the merger of electrocatalysis with oxidative CÀH activation, thus avoiding the use of often toxic metal oxidants. [11] Compared with rhodium [12] and iridium [13] electrocatalysis, economically attractive ruthenaelectrocatalysis continues to be underdeveloped. [14] Within our program on electrochemical C À H activation, [15] we have now devised a sustainable ruthenaelectro-catalyzed three-component reaction to assemble versatile isoquinolines in a domino manner.…”

“…Therefore, we employed a larger reaction flask, facilitating the H 2 dispersion into the expanded volume (Table 1, Entry 10). Further, we employed an oil bubbler, which allowed for the H 2 release, benefiting the chemoselectivity for product 3 aa formation ( Table 1, Entries 11,12,and the SI). With air, oxygen or with Cu(OAc) 2 as the oxidant, unsatisfactory results were obtained, reflecting the unique efficacy of the electrocatalysis (Table 1, Entries 13-15).…”

The electrochemical three‐component assembly of isoquinolines has been accomplished by ruthenaelectro‐catalyzed C−H/N−H functionalization. The robustness of the electrocatalysis was reflected by an ample substrate scope, an efficient electrooxidation, and an operationally friendly procedure. The isolation of key intermediates and detailed mechanistic studies, including unprecedented cyclovoltammetric analysis of a seven‐membered ruthenacycle, provided support for an unusual ruthenium(II/III/I) regime.

“…Sulfur-based TMX, for instance, required the shuttling of soluble lithium and sodium polysulfides, intermediate reaction products, to be carefully addressed, while more in general, volume variations remained as a major limit. [130][131][132] Transition metal chalcogenides such as SnS and SnS 2 , which are subjected both to conversion-alloying mechanism, exhibit high theoretical capacity but bear with themselves the disadvantage of low intrinsic diffusion kinetics and a large volume change. Various approaches have been adapted in order to overcome these drawbacks.…”

IntroductionAs renewable energy sources are taking a wider share of worldwide energy production, [1] grids reliability and utilization efficiency are plummeting. [2,3] This is mainly due to intermittency and discontinuity of power sources, such as wind and solar, which determine uncertainties in energy production capability and in fulfilling the instantaneous energy demand. This aspect, in turn, sensibly increases the unpredictability of energy prices spikes and marginal and maintenance costs of traditional fossil fuel plants, which are demanded Since the breakthrough achieved in the research around material intercalating lithium, almost a decade has passed before the commercialization of the first lithium-ion battery (LIB). On the brink of an energy voracious future, convergence of scientific efforts over efficient and low-cost energy production and storage would be advantageous and beneficial. The research hovering around sodium-ion rechargeable batteries (SIBs), a more sustainable alternative to LIBs, has been observing a positive momentum for ten years now, and chemically stable and electrochemically performing anode and cathode materials represent important milestones on the path toward a commercial full-cell. Material science breakthroughs achieved in carbon and graphite based matrices, layered and open framework structures, and sodium storing alloys, disclose new full-cell set up opportunities going beyond traditional "rocking chair" configuration. In this contribution an in-depth analysis of chemical and physical principles lying beyond the energy storage provided by SIBs most recently investigated active materials is given. In the second half of the review, challenges, opportunities, and state-of-the art description of full-cell SIBs lab scale prototypes are discussed. The latter, indeed, stands for a technological validation of a low-cost alternative to lithium-ion batteries guaranteeing energy densities close to 150 Wh kg −1 . Sodium-Ion Batteriesdiscontinuously to provide for power unbalances between demand and supply. In general, resilience to these drawbacks would be higher providing an incremented flexibility from demand response resources, interregional energy transmission, and energy storage. Plenty of energy storage systems (ESS) are being utilized to curb renewable energy sources intermittency. Among them, worth to be listed are hydroelectric (pumped hydro), mechanical (flywheels and compressed air), and electrochemical (lead-acid, Na-S, Na-NiCl 2 , and Li-ion batteries). [4] Nevertheless not all the previously cited energy storage technologies are comparable one with another in terms of scalability, environmental impact, investment costs, maintenance, and moreover, responsivity to energy needs. Batteries energy storage, directly suppling electric energy without requiring any mechanical-to-electrical energy transducer, surely represents the most versatile appliance. In particular, intrinsic flexibility of modern Li-ion batteries coupled to renewable power plants, ensures the proper response not...
