MOFs-derived porous Mn2O3 as high-performance anode material for Li-ion battery

Abstract

MOFs-derived porous Mn₂O₃ have been synthesized by the high-temperature calcination of a metal–organic framework, [Mn(Br₄-bdc)(4,4′-bpy)(H₂O)₂]_n (Br₄-bdc = tetrabromoterephthalate and 4,4′-bpy = 4,4′-bipyridine). The porous Mn₂O₃ as an anode material for lithium ion batteries displays excellent performances, 705 mA h g⁻¹ after 250 cycles at 1 A g⁻¹.
