Mn3O4 nanocrystals anchored on multi-walled carbon nanotubes as high-performance anode materials for lithium-ion batteries

Facile synthesis and characterization of Mn3O4 nanoparticles by auto-combustion method

“…In particular, Mn 3 O 4 draws increasing interest owing to its intriguing phonic, optical, magnetic and electrochemical properties [4]. Mn 3 O 4 is known to be an effective and inexpensive catalyst to limit the emission of NOx and CO [1,5], and it can also be used as electrode materials for lithium ion batteries [6] and supercapacitors [7]. Nanometer-sized Mn 3 O 4 is expected to display better performance in these aspects of application on account of the greatly reduced size and notably increased surface area.…”

Mn3O4 anchored on carbon nanotubes as an electrode reaction catalyst of V(IV)/V(V) couple for vanadium redox flow batteries

“…The On the basis of the obtained results and the literature about this aspects [29,30], the Mn3O4/MWCNTs composite preparation process is illustrated in Fig. 2.…”

Carbon nanotubes decorated by mesoporous cobalt oxide as electrode material for lithium-ion batteries

“…CNTs have unique morphological characteristics: in addition to the high surface area it is the extremely high aspect ratio which efficiently can generate interconnected networks of percolating CNT. The pore structure of CNTs increases the contact area with the electrolyte, thereby improving the electrochemical performance of CNT-based materials [24] in contrast to some other carbon materials, such as activated carbons [25,26]. This has been shown for several MO.…”

“…conversion reactions, which are much higher than in graphite, transition-metal oxide nanoparticles (MO-NPs with M = Co, Ni, Cu or Fe) are particularly promising anode materials [11][12][13]. However, large volume expansion upon Li insertion/extraction destabilizes the structure of the MO and derogates the electrical contacts within the materials and towards the current collector, resulting in poor cyclability and rate capabilities.…”

“…This has been shown for several MO. MnO/CNT composites has generated a substantial increase in performance [27] as well as exohedral functionalization of CNTs by Mn 3 O 4 [24]. Even filling of CNTs is a potential route as shown by Yan et al in the case of Fe 2 O 3 nanoparticles [28].…”
