The present study is to investigate the formation of 1D carbon coated with noble metal core shellâ??s nanoparticles and the novel composites helps in the fabricating a Hybrid lead-acid battery to improve the electrochemical performance for high end application-hybrid batteries. The core shell (Ag@Au) was synthesized using natural reducing agents favoring the â??go green methodsâ? by first reducing the silver salts using Cymbopogon citratus (lemon grass) extract followed by the addition of gold solution (Chlorauric acid) on the surface of silver nanoparticles where in Nano silver acts as a self-reducing agent to form Nano gold shell as shown in the schematic diagram (A). The core shell of Au@Ag Nano particles was synthesized by using lemon grass as reducing agent for the Nano core gold (chlorauric acid) followed by the addition of silver salt solution kept in Hydrazine atmosphere to obtain the core shell Au@Ag, ( Schematic diagram B )which leads to the formation of bimetallic Au coreâ??Ag shell & Ag Core- Au shell nanoparticles. The well stabilized core shell was further added to functionalize MWCNTCOOH & MWCNT-NH2 to make the Nano-composites of MWCNT- Noble metal core shell, investigated through XRD & TEM. The Nano composite is coated on the lead acid battery grid and the same was confirmed by SEM & EDAX. The capacity of the battery performance was improved to 10 % from C1 & C10 test.
