Nickel phosphate (NiP) was synthesized by sono-chemical synthesis followed by calcination at 400 °C for 5 h. Synthesized NiP was blended with various concentrations (10, 30 and 50 wt%) of multiwalled carbon nanotubes (MWCNTs) to prepare the nanocomposites that were then characterized in terms of microstructure, morphology, composition, and electrochemical performance. Microscopic analysis showed the presence of uniformly distributed MWCNTs in NiP matrix in case of nanocomposites containing 50 wt% MWCNTS (NiP50CNT50) resulting in its better electrochemical performance than the other compositions. X-ray diffraction and Fourier transformed infra-red spectroscopic analysis also confirmed the synthesis of MWCNTs/NiP nanocomposites by showing that the characteristics peaks becoming broader and intense due to incorporation of CNTs. The electrochemical analysis of all the prepared …
