Abstract
Low volumetric-energy-density caused by low tap density of nanomaterial seriously restricts the application of nanomaterial in lithium-ion batteries. Here, to solve this problem, micron-sized Fe2O3 secondary particles (MFSPs) with high tap density (2.8 g cm−3) are synthesized via a facile way. As a result, ultrahigh volumetric-energy-density of 1490 mA h cm−3 is obtained after 100 cycles at C/2 (∼500 mA g−1). Densely packed structure of MFSPs exhibits well structural stability and electrical conductivity. For the high areal mass loading of 4.02 mg cm−2, an areal capacity about 3 mA h cm−2 is achieved.
