View more“We’ve found that chicken eggshells can be used as electrodes – a conductor of electricity - in powering batteries. Eggshells contain a high level of calcium carbonate, and when they are baked and crushed, their chemical compositions change and they become a more efficient electrode and conductor of power,” Dr Minakshi said.
The core–shell electrode structure is formed by depositing (CoCrFeMnNi) 3 O 4 (HEO) nanoparticles on a conductive carbon (CC) cloth followed by electrodeposition of a shell layer composed of highly conductive polypyrrole (PPy) nanospheres.
Such lack of suitable core materials can be compensated by fabricating a shell to yield a core–shell structure. The use of carbon materials as the shell layer may provide high specific surface area and elevated electrical conductivity for the electrode .
Chicken eggshells may be the answer to developing safer, sustainable and cost-effective rechargeable battery storage systems, according to new research.
