An ultrasound-assisted approach to synthesize Mn3O4/RGO hybrids with high capability for lithium ion batteries†
Abstract
A facile, low-cost and green ultrasound-assisted method was developed to ultra-fast synthesize Mn3O4 nanosheets supported on reduced graphene oxide (RGO). Such hybrid materials exhibited ultrahigh performance as lithium ion battery (LIB) anodes, whose specific capacity reached more than 1400 mA h gā1 after 40 cycles at a current density of 100 mA gā1 (based on the mass of Mn3O4). The remarkably enhanced LIB performance could be attributed to their layer-by-layer aggregation structures.
