Porous NiO architecture prepared with coordination polymer precursor as a high performance anode material for Li-ion batteries

Abstract

By the calcination of a coordination polymer precursor, a porous flower-like NiO architecture was conveniently synthesized. The electrode fabricated by it exhibited excellent cycling stability and high rate performance in electrochemical tests. The lithium storage could be maintained at ∼1000 mA h g⁻¹ with a high coulombic efficiency (∼95%), which is among the best reported results.
