“…On the other hand, doping of carbon materials with heteroatoms such as nitrogen, sulphur, phosphorous, or boron can improve ionic and electronic conductivity [14][15][16]. Also, doping-induced defects on carbon could create localised active sites to accommodate sodium ions and favour ion transfer, giving rise to higher sodium storage performance [17,18].…”

“…Doping hard-carbon or graphene-like structures creates a defect sites to absorb sodium ions and improves the electrode-electrolyte interaction. [108] Biomass derived carbons, which have been widely investigated due to their low production cost and low energy consumption during the synthesis procedure, indeed often exhibit very low Coulombic efficiency. [107] In another work, nitrogen rich hard carbon derived from biomass with improved capacitance exhibited stable 204 mAh g −1 for over 1000 cycles at 1 A g −1 but a Coulombic efficiency of 34% in the first cycle.…”

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...

“…On the other hand, however, the absence of nitrogen was clearly observed for the sample HCS ( Figure S7.2). The X-ray diffraction (XRD) patterns of both samples exhibit two prominent peaks at ~22 and ~42 degrees two theta which can be attributed to the crystallographic planes of (002) and (100) of graphitic domains in the hard carbon (Figure 7.2a) [20]. Although no significant change in the peak patterns were observed after treatment with ethylenediamine, an increase in the d- (Figure 7.3a and b).…”
