“…Nevertheless, the Na-storage mechanisms have not been intensively discussed. For example, it is well known that the modified Co 3 O 4 [23][24][25][26][27][28] shows reversible capacity of more than 700 mAh g -1 in Li-ion batteries. Very recently, Wen and co-workers [29] have investigated bowl-like hollow Co 3 O 4 microspheres as anodes for Na-ion batteries but with unsatisfactory electrochemical properties.…”

A composite of transition metal oxide Co 3 O 4 and multiwalled carbon nanotubes (MCNTs) was applied as an anode material for sodium-ion batteries via a simply modified solid-state reaction and sonication method. The as-prepared Co 3 O 4 /MCNTs composite shows improved electrochemical performance than bare Co 3 O 4 owing to the Co 3 O 4 /MCNTs nanostructure that benefits Na ion and electronic transport together with buffering the large volume change of Co 3 O 4 during charging and discharging process. Additionally, the Na-storage behavior and the original capacity loss of Co 3 O 4 based on the conversion reaction have been investigated through cyclic voltammogram, X-ray diffraction, field-emission scanning electron microscopy, high-resolution transmission electron microscopy, and selected area electron diffraction. It is firstly demonstrated that in discharge state, Co 3 O 4 particles initially react with Na to produce CoO and then is further reduced to nanosized Co in an amorphous sodium oxides matrix. In the charge process, Co nanoparticles were partially oxidized to Co 3 O 4 , the other part of the CoO remain leading capacity loss. These results offer new insights into the electrochemical process of transition metal-based anode materials for Na-ion batteries.

“…The hybrid configuration is expected to retain the advantages of each component and, at the same time, provide synergetic effects that enhance the physicochemical properties such as electrochemical reactivity and mechanical stability [21]. Recently, several iron oxide@cobalt oxide hybrid materials have been reported with enhanced lithium storage capability, such as Fe 2 O 3 @Co 3 O 4 @C composite nanoparticles [22], Fe 2 O 3 @Co 3 O 4 nanowire arrays [23], and Co 3 O 4 @Fe 2 O 3 core–shell nanoneedle arrays [24]. In addition, the construction of hierarchical hollow nanostructures was found to be an effective way to accommodate the large volume changes associated with electrochemical reactions [25, 26].…”

Transition metal oxides are promising candidates for the high-capacity anode material in lithium-ion batteries. The electrochemical performance of transition metal oxides can be improved by constructing suitable composite architectures. Herein, we demonstrate a metal–organic framework (MOF)-assisted strategy for the synthesis of a hierarchical hybrid nanostructure composed of Fe2O3 nanotubes assembled in Co3O4 host. Starting from MOF composite precursors (Fe-based MOF encapsulated in a Co-based host matrix), a complex structure of Co3O4 host and engulfed Fe2O3 nanotubes was prepared by a simple annealing treatment in air. By virtue of their structural and compositional features, these hierarchical composite particles reveal enhanced lithium storage properties when employed as anodes for lithium-ion batteries.

“…For example, Fan and coauthors reported the improved LIBs performance in the branched a-Fe 2 O 3 /SnO 2 nano-heterostructures where a-Fe 2 O 3 branches may relieve the stress exerted on inner SnO 2 nanowires due to the severe volume change arising from alloyingdealloying processes [12]. Xiong et al prepared Fe 2 O 3 @Co 3 O 4 array with large reversible capacity and excellent cycling life, which is mainly benefited from unique hierarchical nanowire architecture and an elegant synergistic effect of two electrochemically active materials [22]. Additionally, Wu et al designed ternary core/shell structure of Co 3 O 4 /NiO/C nanowire arrays as high performance anode material for LIBs.…”
