Abstract

Ni-NiO-CNT composite synthesized by swift and simple combustion process is investigated as anode for Li-ion batteries (LIB) and also as an electro-catalyst for oxygen evolution reaction (OER) in alkaline medium. The binder free, electrical conductor less, free standing anode fabricated from Ni-NiO-CNT displays a stable capacity of 736 mAh g�1 at a current density of 200 mAg�1 for the investigated 50 cycles, the exhibited capacity being higher than the theoretical capacity of NiO and carbon. The hybrid composite also exhibits excellent OER activity, achieving current density of 10 mA cm�2 at a lower over potential (h) of 320 mV. The presence of Ni nanoparticles and porous sponge like structure of the composite is the main reason for this high performance. Such multifunctional materials could emerge as promising for realizing future energy storage and conversion approaches
