In this work, a core-shell structure Fe2O3@C hollow nanospheres derived from metal-organic frameworks is used as anode material for Liion batteries. This material delivers reversible capacity of 928 mAh g-1 at 0.2 A g-1 in 1 M LiPF6 in ethylene carbonate: dimethyl carbonate=1:1. While1 M Lithium bis (trifluoromethane sulfonyl) imide is used as conductive salt, it delivers only 644 mAh g-1 at 0.2 A g-1. In operando synchrotron radiation diffraction revealed that the intermediate phases LixFe2O3 (R3 ̅ m, hexagonal) and LixFe2O3 (Fd3 ̅ m, Li-lean) form and subsequently convert to LixFe2O3 (Fd3 ̅ m, Li-rich), which finally transforms into Fe, Li2O, and LixFe2O3 (Fd3 ̅ m, X phase). During the de-lithiation process, the material does not return to the initial Fe2O3 structure. Instead, the partially de-lithiated Lix-1Fe2O3 (Fd3 ̅ m, X phase) and an amorphous metallic Fe phase remain. The Fe K-edge transition and the formation of Fe are confirmed by the in operando X-ray absorption spectroscopy measurement. Furthermore, the resistive contributions of this material in the two type of Li-salt are evaluated by electrochemical impedance spectroscopy, which highlight a different type of solid electrolyte interphase induced by the salt. This work provides fundamental insights on understanding the lithium-ion storage mechanism in conversion-type electrodes.

“…More complicatedly, a bimetallic Ni‐Co‐ZIF was used as the starting precursor. Furthermore, hierarchical hollow hybrid Fe 2 O 3 @MIL‐101/C materials were prepared as anode materials of SIBs by employing a generic template‐free strategy . The hollow nanostructure ensured a stable reversible capacity of 710 mA h g −1 , and after 200 cycles, it can retain at 662 mA h g −1 with a retention of 93.20%.…”

production, especially for hydroelectricity, sunlight, and wind energy, which cannot be gathered or released when they are needed. [5][6][7][8] Electrochemical energy storage devices provide a promising approach for the storage of electric energy from these sources. [9][10][11] Currently, carbonaceous materials have attracted much interest for their extensive applications including adsorption, [12] catalysis, [13] batteries, [14] fuel cells, [15,16] supercapacitors, [17,18] and drug delivery and imaging. [19] In addition, some sensors are also one of the important applications of carbonaceous materials, because they are closely related to human health. [20,21] For instance, Emran and co-workers [22] constructed ultrasensitive biosensors with N-doped mesoporous carbon (NMC)-based electrodes for in vitro monitoring of DA released from living cells. With the further study of the experiment, they also designed a series of S-doped carbon materials for a wider detection of DA, UA (uric acid), and AA (ascorbic acid). [23,24] The advantages of easy preparing, nontoxic and excellent electrical conductivity of carbonaceous materials, which are rare among energy storage materials, make carbonaceous materials superior to most of the energy storage materials. [25][26][27] There are varieties of approaches for the preparation of carbon materials, such as directly carbonizing from organic precursors, physically or chemically carbonizing from carbon, template methods using zeolites and mesoporous silica, solvothermal and hydrothermal methods with elevated temperature, the electrical arc methods, and chemical vapor decomposition (CVD) methods. [28][29][30][31][32][33][34] Among all these approaches, directly carbonizing from organic precursors is the most frequently used method to prepare nanoporous carbons (NPCs) due to its flexibility and simplicity. [35][36][37] However, these NPC materials present certain drawbacks, such as low surface areas, disordered structures, and ununiformed sizes, which will greatly limit their applications. [25] As studies have progressed, researchers found that carbon materials derived from metalorganic frameworks (MOFs) could overcome these limitations.Metal-organic frameworks, which are also named porous coordination polymers (PCPs), are crystalline porous materials with periodic network structures formed by metal ions (or metal clusters) and organic ligands. [38][39][40][41][42] They are usually prepared by solvothermal methods and used as precursors or templates to form nanostructured materials. [43][44][45] So far, many researchers have highlighted the advantages of MOFs. For Carbon materials derived from metal-organic frameworks (MOFs) have attracted much attention in the field of scientific research in recent years because of their advantages of excellent electron conductivity, high porosity, and diverse applications. Tremendous efforts are devoted to improving their chemical and physical properties, including optimizing the morphology and structure of the carbon materials, compositing them wi...

“…Hematite α-Fe 2 O 3 as well as magnetite Fe 3 O 4 have been taken into consideration and their conversion reactivity has been widely characterized. Recently using as template a metal-organic frameworks a new Fe 2 O 3 carbon composite has been proposed by Li et al [116] Thanks to its stable high porous structure that can shorten ionic diffusion length and provide efficient channels for mass transport, the as prepared material manifests outstanding electrochemical performance. In a one-pot hydrothermal synthesis they have been able to synthesize nanometric Fe 3 O 4 particles embedded in a carbon matrix, the latter expected to take upon itself the sluggish electronic conduction of magnetite and provide a mechanical reinforcement capable of withstanding volume expansion stresses.…”

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...
