“…Similar to Fe 2 O 3 , natural abundance, high theoretical capacity (926 mAh/g) and low cost are its attractions, but huge volume expansion and severe particle agglomeration while cycling need to be overcome. A unique Fe 3 O 4 @PANI composite with yolk-shell micro-nanoarchitecture was obtained by Wang's group [128]. Figure 17 vividly illustrates its formation process.…”

Conducting polyaniline (PANI) with high conductivity, ease of synthesis, high flexibility, low cost, environmental friendliness and unique redox properties has been extensively applied in electrochemical energy storage and conversion technologies including supercapacitors, rechargeable batteries and fuel cells. Pure PANI exhibits inferior stability as supercapacitive electrode, and can not meet the ever-increasing demand for more stable molecular structure, higher power/energy density and more N-active sites. The combination of PANI and other active materials like carbon materials, metal compounds and other conducting polymers (CPs) can make up for these disadvantages as supercapacitive electrode. As for rechargeable batteries and fuel cells, recent research related to PANI mainly focus on PANI modified composite electrodes and supported composite electrocatalysts respectively. In various PANI based composite structures, PANI usually acts as a conductive layer and network, and the resultant PANI based composites with various unique structures have demonstrated superior electrochemical performance in supercapacitors, rechargeable batteries and fuel cells due to the synergistic effect. Additionally, PANI derived N-doped carbon materials also have been widely used as metal-free electrocatalysts for fuel cells, which is also involved in this review. In the end, we give a brief outline of future advances and research directions on PANI.

“…Significantly, the specific surface area of NGAs is calculated of 86.94 m 2 g −1 by a BET formula, which is larger than that of the bare NiCo 2 S 4 nanotube (42.86 m 2 g −1 ). Evidently, the porous structure of NGAs with the large surface area and pore volume can availably strengthen the penetration of electrolyte and relieve the volume charge of NiCo 2 S 4 nanotubes during charge–discharge cycling process [7].…”

“…As everyone knows, the performances of LIBs have a great relationship with the species of electrode materials [4,5]. In a variety of anode materials, transition metal oxides (TMOs) have been widely studied due to their high theoretical capacity, low cost and environmental friendly in recent years [6][7][8]. However, their poor electron conductivity usually leads to low rate capability, which greatly affects their practical application [9].…”

Three-dimensional nickel cobalt sulphide (NiCo 2 S 4) nanotubes-graphene aerogel composites (NGAs) are firstly assembled by an electrostatic interaction between the diallyldimethylammonium chloride-modified NiCo 2 S 4 nanotubes and graphene oxide (GO) sheets, followed by a steerable hydrothermal and freeze-drying process. The final samples are characterised by scanning electron microscope, transmission electron microscopy, X-ray diffraction and Brunauer-Emmett-Teller. The results reveal that the NiCo 2 S 4 nanotubes with a uniform diameter of about 200 nm tightly anchor onto the crumpled surface of graphene sheets and GO sheets self-assemble into an interconnected porous structure. When the composites are evaluated as an anode for lithium-ion batteries (LIBs), presenting an extremely admirable cycling stability (967.5 mAh g −1 after 100 cycles at a current density of 100 mA g −1) and excellent rate capability (as high as 654.7 mAh g −1 at a large rate of at 2000 mA g −1). This work proved that the NGAs may have a great application in LIBs.

“…Nanosizing and modification with carbon materials are the two main methods of resolving these issues. Reducing the bulkstructured Fe 3 O 4 to nanostructures with different morphologies, such as nanorods, [17] nanowires, [18] nanoballs, [19] and nanosheets, [20] is beneficial for increasing the specific surface area of the anode material, which can then shorten the transmission distance of Li + /e À and strengthen the diffusion kinetics, resulting in high rate capacities and better cycling stability. However, nano-sized Fe 3 O 4 tends to agglomerate due to its high surface energy.…”

Iron-based oxides are ideal candidates for a new generation of lithium-ion battery (LIB) anode materials owing to their high theoretical capacity and abundance, low cost, and non-toxicity. However, the shortcomings of nanoparticle agglomerations with low electrical conductivity, volume expansion, and easy powdering during the cycling process hinder their commercialization. Herein, a silkworm-chrysalisnet-like (SCN) Fe 3 O 4 /rGO/mesoporous carbon nano-architecture composite was prepared by combining an in-situ sol-gel coating strategy and a one-step hydrothermal reaction process. The overall microstructure of the electrode material with a unique SCN structure could effectively create a synergistic effect to enhance the electrochemical performance. As a result, the capacity of rGO-Fe-C0.5 could reach 916.4 mA h g À 1 after 100 cycles at a current density of 0.5 A g À 1 , and slow capacity attenuation of 0.033% per cycle after 500 cycles at 2 A g À 1 was achieved. This work provides new insights into the design of Fe 3 O 4 based composite for application in lithium-ion batteries.
