A composite of Si nanoparticles and a two dimensional porous conductive Ni3(2,3,6,7,10,11-hexaiminotriphenylene)2 (Ni3(HITP)2) metal–organic framework (MOF), namely Si/Ni3(HITP)2, is suggested as a potential anode material for Li-ion batteries.
Impressive Li-ion storage, fast charge–discharge and ultra long life spans more than 1000 cycles with high capacity retention are simultaneously obtained in CoCOP nanowires.
