Hierarchical structured materials for Li-ion batteries with high rate capability and tap density

In this paper by Zhang et al., specially structured precursors (iron phosphate nanoplates) are lithiated to LiFePO4/C quasi-spheres which show both superior high rate capability and high tap density.

The LiFePO4/C materials have hierarchical structures with discharge capacities of more than 120, 110, and 90 mAh g−1 at rates of 5 C, 10 C and 20 C, respectively. They also show a high tap density of 1.4 g cm−3 as cathode materials for lithium ion batteries.

micro-nano hierarchical structureThis hierarchical structured LiFePO4/C material could take us a step closer to real and large-scale applications for lithium ion batteries.
