Nanometer-sized Mn3O4 powders were successfully synthesized using flame spray pyrolysis, and exhibited excellent performance as anode material for lithium-ion batteries.
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).
