“…23,27 To addressing these drawbacks, one general strategy is to combine designed α-Fe 2 O 3 nanostructures with carbon conducting matrixes such as thin-layer carbon shells, carbon nanotubes (CNT) and graphene or reduced graphene oxide (r-GO), forming hybrid composites to keep the structural integrity and improve the electrical conductivity of α-Fe 2 O 3 based anode materials. [27][28][29][30] Especially, graphene with outstanding electrical conductivity, and excellent mechanical flexibility is an ideal conducting host for α-then vacuum freeze-dried. Next, 15 mg of the precipitate was dispersed in 35 mL of the solution containing of 0.432 g of FeCl 3 ·6H 2 O and 0.864 g of NaNO 3 under stirring for 0.5 h.…”

The α-Fe 2 O 3 nanorods/reduced graphene oxide nanosheets composites (denoted as α-Fe 2 O 3 @r-GO NRAs) are fabricated by a facile and scalable seeds-assisted hydrothermal growth route, in which the α-Fe 2 O 3 nanorods are assembled onto the side surfaces of r-GO nanosheets. Such α-Fe 2 O 3 @r-GO hybrid nanostructures are tested as anodes for both Li-ion and Na-ion batteries (LIBs and SIBs), which exhibits excellent performance with high capacity and long-cycling stability. When used for LIBs, the hybrid α-Fe 2 O 3 @r-GO NRAs electrode exhibits a highly stable Li + storage capacity of 1200 mAh g -1 after 500 cycles at 0.2 C and excellent rate capability. Moreover, the hybrid α-Fe 2 O 3 @r-GO NRAs also displays its versatility as an anode for SIBs, which delivers high reversible Na + storage capacity of 332 mAh g -1 at 0.2 C over 300 cycles with long-term cycling stability. The excellent electrochemical performance for the hybrid α-Fe 2 O 3 @r-GO NRAs anodes could be ascribed to the synergistic effect between the α-Fe 2 O 3 nanorods arrays and reduced graphene oxide nanosheets, which could availably promote the charge transport and accommodate the volume change upon long-term charge-discharge process for reversible Li + or Na + storage.

“…Research on the influence of amount and type of CNTs on the performance of LiFePO 4 was carried out for optimizing electrical resistivity, specific capacity, specific surface area, and particle size distribution. Jin et al reported that use of MWNTs ($5 wt%) with LiFePO 4 as a filler material showed superior electrochemical properties compared with classic composite cathode [60][61][62]. A close look at 3D networks ( Fig.…”

“…In general, electrochemical lithium storage of up to 8 Li + /f.u. in CoFe2O4 follows a conversion mechanism (Equation (D)), which may be preceded by initial intercalation of Li + ions into the original ferrite structure (Figure 4a) [45,51,61,62].…”

Downsizing well-established materials to the nanoscale is a key route to novel functionalities, in particular if different functionalities are merged in hybrid nanomaterials. Hybrid carbon-based hierarchical nanostructures are particularly promising for electrochemical energy storage since they combine benefits of nanosize effects, enhanced electrical conductivity and integrity of bulk materials. We show that endohedral multiwalled carbon nanotubes (CNT) encapsulating high-capacity (here: conversion and alloying) electrode materials have a high potential for use in anode materials for lithium-ion batteries (LIB). There are two essential characteristics of filled CNT relevant for application in electrochemical energy storage: (1) rigid hollow cavities of the CNT provide upper limits for nanoparticles in their inner cavities which are both separated from the fillings of other CNT and protected against degradation. In particular, the CNT shells resist strong volume changes of encapsulates in response to electrochemical cycling, which in conventional conversion and alloying materials hinders application in energy storage devices.(2) Carbon mantles ensure electrical contact to the active material as they are unaffected by potential cracks of the encapsulate and form a stable conductive network in the electrode compound. Our studies confirm that encapsulates are electrochemically active and can achieve full theoretical reversible capacity. The results imply that encapsulating nanostructures inside CNT can provide a route to new high-performance nanocomposite anode materials for LIB.
