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

摘要

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 similar to 1000 mA h g(-1) with a high coulombic efficiency (similar to 95%), which is among the best reported results.
