“…Fe3O4 (magnetite) electrodes have also been extensively researched as potential Li-ion anodes, some reports of which are outlined in Table 1 Fe3O4/C Nanospindles 749 (C/2) 600 (80) [173] Fe3O4/C Nanowires ~800 (C/10) ~800 (50) [174] Fe3O4/C Nanocrystals ~610 (C/10) ~635 (50) [175] Fe3O4/C Nanofibres 1551 (C/5) 1007 (80) [176] Fe3O4/C Spheres 1259 (C/5) 984 (70) [177] Fe3O4/graphene Nanoparticles ~1320 (C/10) ~900 (50) [178] Despite earlier reports of poor capacity retention among Co3O4 nanowires [188], recent examples have displayed excellent Li-ion capabilities, including significant rate performance [189,190]. Initially, the poor capacity retention of the Co3O4 nanowires was attributed to inter-particle disconnect following complete conversion, resulting in Co nanograins electrically isolated from one-another by insulating polymeric layers [188].…”

Rights © Tsinghua University Press and Springer-Verlag Berlin ABSTRACTThe performance of the lithium-ion cell is heavily dependent on the ability of the host electrodes to accommodate and release Li + ions from the local structure. While the choice of electrode materials may define parameters such as cell potential and capacity, the process of intercalation may be physically limited by the rate of solid-state Li + diffusion. Increased diffusion rates in lithium-ion electrodes may be achieved through a reduction in the diffusion path, accomplished by a scaling of the respective electrode dimensions.In addition, some electrodes may undergo large volume changes associated with charging and discharging, the strain of which, may be better accommodated through nanostructuring. Failure of the host to accommodate such volume changes may lead to pulverisation of the local structure and a rapid loss of capacity. In this review article, we seek to highlight a number of significant gains in the development of nanostructured lithium-ion battery architectures (both anode and cathode), as drivers of potential next-generation electrochemical energy storage devices.

“…However, the synthesis of these anisotropic iron oxide nanocrystals is nontrivial, more so for one-dimensional (1D) systems such as nanorods (NRs), nanotubes (NTs), and nanowires (NWs), with different strategies being proposed to reach this goal [11][12][13]. Among them, a process involving the dehydration and/or reduction of premade elongated β-FeOOH with a channel-type nanoporous structure (akaganeite)…”

Synthesizing Iron Oxide Nanostructures: The Polyethylenenemine (PEI) Role

et al. 2017

Controlled synthesis of anisotropic iron oxide nanoparticles is a challenge in the field of nanomaterial research that requires an extreme attention to detail. In particular, following up a previous work showcasing the synthesis of magnetite nanorods (NRs) using a two-step approach that made use of polyethylenenemine (PEI) as a capping ligand to synthesize intermediate β-FeOOH NRs, we studied the effect and influence of the capping ligand on the formation of β-FeOOH NRs. By comparing the results reported in the literature with those we obtained from syntheses performed (1) in the absence of PEI or (2) by using PEIs with different molecular weight, we showed how the choice of different PEIs determines the aspect ratio and the structural stability of the β-FeOOH NRs and how this affects the final products. For this purpose, a combination of XRD, HRTEM, and direct current superconducting quantum interference device (DC SQUID) magnetometry was used to identify the phases formed in the final products and study their morphostructural features and related magnetic behavior.

“…Methods include: decomposition [8], microwave-hydrothermal [9], ultra-sonication assisted [10], hydrolysis of iron chloride [11], gas-liquid interfacial synthesis [12], the reverse micelle method [13], laser pyrolysis [14], laser ablation [15] and liquid-solid-solution [16]. They are also a result of high iron loading in carbon nanotube (CNT) synthesis [17] and similar results can be achieved by filling CNTs [18,19].…”

“…Functionalisation has the potential to improve biocompatibility, improve selectivity [22] and enhance functionality [3]. The relatively low synthesis temperature (250 o C) to produce encapsulated nanoparticles has only been seen in a handful of journals [9,12,[23][24][25] and none using a one-step synthesis route. The system introduced in this study avoids complex synthesis routes and provides a low cost, simple route for protecting iron rich nanoparticles.…”
