Facile synthesis of nanosized Mn3O4 powder anodes for high capacity Lithium-Ion battery via flame spray pyrolysis

Abstract

Mn3O4 powders with nanometer size are successfully synthesized by a simple one-step method via flame spray pyrolysis. The precursor droplet is generated by heating under high temperature flame with fixed flow rate, and the exothermic reaction is induced to form nanosized Mn3O4 powders. When used as anode material for lithium-ion battery, the Mn3O4 exhibits good cycling capacity and rate performance. It delivers a specific capacity of 1,182 mA h g−1 over 110 cycles at a current density of 200 mA g−1, and has a high capacity of 140 mA h g−1 at 5,000 mA g−1.

Experimental Investigation of Pure Spinel Mn3O4 Properties Synthesized through Chemical Spray Pyrolysis for Future Gas Sensor Application

“…[20,21] The expanding attention in this material Mn 3 O 4 has been motivating the search for deposition techniques with a high-quality. In fact, several physical and chemical elaboration techniques are used for the fabrication of Mn 3 O 4 thin layers such as, chemical vapor deposition, [22] Metal-Organic Chemical Vapor Deposition (MOCVD), [23] hydrothermal technique, [24] spray pyrolysis [25,26] and Pulsed Laser Deposition (PLD). [27] However, some of them can introduce defects and impurities on material.…”

Hydrothermal fabrication of Sn/SnO/SnO2 hybrid nanocomposites as highly reliable anodes for advanced lithium-ion batteries

“…Researchers are now trying to develop different anode materials with both a good energy density and a long cycle life to suit such energy needs. Various materials with a high capacity value of 200-4200 mA h g À1 , namely silicon, 5 tin, 6 antimony, 7 aluminium, 8 cooper(II) oxide, 9 molybdenum oxide, 10 cobalt oxide, 11 manganese oxide, 12 titanium oxide, 13 rGO, 14 tin(II) oxide, 15 and tin(IV) oxide, 16 have been studied extensively. Among them, tin-based materials have received a lot of interest among the alternative conversion anode materials due to their good theoretical capacities (i.e., 992, 875 and 782 mA h g À1 for Sn, SnO and SnO 2 , respectively), excellent earth-abundance, low cost, and non-toxicity.…”
