“…7,8 It has also been noted that at high current densities, additional performance degradation takes place, resulting not only from sluggish kinetics for charge transfer and ionic diffusion but also from Fe 3 O 4 's intrinsically low electronic conductivity. 9,10 Two strategies have been usually employed to circumvent all of these limitations with the goal of generating Fe 3 O 4 anodes with improved and enhanced rate capability and cycling stability. One protocol has been to optimize the size of Fe 3 O 4 nanoparticles so as to improve the Li-ion diffusion and electron transport within the metal oxide nanoparticles.…”

Fe 3 O 4 nanoparticles (NPs) with an average size of 8-10 nm and a loading ratio of 50 wt% have been successfully attached onto the external surfaces of multi-walled carbon nanotubes (MWNTs) by means of three different preparative approaches, namely a sonication method, a covalent attachment protocol, as well as a non-covalent π-π interaction strategy. Specifically, the Fe 3 O 4 NPs associated with the sonication method lie directly on the outer surfaces of the MWNTs. Particles covalently attached onto the MWNTs formed amide chemical bonds through the mediation of the amorphous (3-aminopropyl) triethoxysilane (APTES) linker. Finally, particles were anchored non-covalently onto the underlying conjugated MWNTs via an aromatic 4-mercaptobenzoic acid (4-MBA) linker. Both structural and electrochemical characterization protocols have been used to systematically correlate the electrode performance with the corresponding attachment strategies. Fe 3 O 4 -MWNT composites generated by the π-π interaction strategy delivered 813, 768, 729, 796, 630, 580, 522, and 762 mAh/g under rates of 200, 400, 800, 100, 1200, 1600, 2000, and 100 mA/g, with 72% retention between cycles 2 and 80, demonstrating both higher capacity and better cycling stability as compared with analogues derived from the physical sonication as well as covalent attachment strategies. This finding may be attributed to the enhanced charge and ion transport coupled with retention of physical contact with the underlying MWNTs after a large volume change during cycling. Our collective results suggest that the non-covalent π-π attachment modality is a more effective preparative strategy for enhancing the performance of MWNT-Fe 3 O 4 composite electrodes after a full discharge process. Lithium ion battery (LIB) applications have experienced significant growth over the past two decades. Today LIBs are widely used and denote the battery of choice for a wide range of applications spanning from portable electronics to electric vehicles.1-5 Although LIBs have shown impressive commercial success, an understanding of the intrinsic functioning of LIB electrodes and of their constituent component materials still represents a subject of significant research. In recent years, the use of energy storage devices has expanded into new areas, including with uninterrupted power sources (UPS), stationary storage batteries (SSBs), and the automotive market, the latter of which encompasses both electric vehicles and hybrid electric vehicles. Hence, the development of LIBs based upon the use of lower cost and more earth abundant materials embodies a highly desirable objective.As an electroactive material, the inverse spinel structure of magnetite (Fe 3 O 4 ) epitomizes a particularly promising candidate for an anode material in LIB, due to its (i) significantly larger reversible capacity (i.e. 926 mAh g −1 , when reacting with eight lithium equivalents), (ii) plentiful earth abundance, and (iii) relative non-toxicity.

Li-ion hybrid supercapacitors (Li-HECs) facilitate effective combination of the advantages of supercapacitors and Li-ion batteries (LIBs). However, challenges remain in designing and preparing suitable anode and cathode materials, which often require tedious and expensive procedures. Herein, we demonstrated that hollow N-doped carbon capsules (HNC) with and without a Fe3O4 nanoparticle core can respectively function as the anode and the cathode in very-high-performance Li-HECs. The Fe3O4@NC anode exhibited a high reversible specific capacity exceeding 1530 mA h g −1 at 100 mA g −1 and excellent rate capability (45% capacity retention from 0.1 to 5 A g −1 ) and cycle stability (>97% retention after 100 cycles). Moreover, high rate performance was achieved in a full-cell using the HNC cathode. By combining the respective structural advantages of the components, the hybrid device with Fe3O4@NC//HN C exhibited a remarkable energy density of 185 W h kg −1 at a power density of 39 W kg −1 . The hybrid device furnished a battery-inaccessible power density of 28 kW kg −1 with rapid charging/discharging within 9 s at an energy density of 95 W h kg −1 .

“…They have low toxicity and high intrinsic density (5.17 g cm −3 for Fe 3 O 4 vs. 2.16 g cm −3 for graphite), and are abundant. In spite of these highly appealing features, their use in LIB anodes is hampered by low electrical conductivity, and fast capacity fading due to severe aggregation of iron oxides particles and large volume changes inherent in the conversion reaction process [5,8,14]. Their hybridization with conductive matrices such as carbon is mostly adopted to resolve these problems.…”

Magnetite, Fe 3 O 4, is a promising anode material for lithium ion batteries due to its high theoretical capacity (924 mA h g −1 ), high density, low cost and low toxicity. However, its application as high capacity anodes is still hampered by poor cycling performance. To stabilize the cycling performance of Fe 3 O 4 nanoparticles, composites comprising Fe 3 O 4 nanoparticles and graphene sheets (GS) were fabricated. The Fe 3 O 4 /GS composite disks of μm dimensions were prepared by electrostatic self-assembly between negatively charged graphene oxide (GO) sheets and positively charged Fe 3 O 4 -APTMS [Fe 3 O 4 grafted with (3-aminopropyl)trimethoxysilane (APTMS)] in an acidic solution (pH = 2) followed by in situ chemical reduction. Thus prepared Fe 3 O 4 /GS composite showed an excellent rate capability as well as much enhanced cycling stability compared with Fe 3 O 4 electrode. The superior electrochemical responses of Fe 3 O 4 /GS composite disks assure the advantages of: (1) electrostatic self-assembly between high storage-capacity materials with GO; and (2) incorporation of GS in the Fe 3 O 4 /GS composite for high capacity lithium-ion battery application.
