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.

The properties and the mechanism of the dry electrodes have been deeply studied. The unique microstructure could also benefit the electrode with better fast-charging ability and longer cycle life. Thus, we believe this work paves a more efficient way for battery manufacturing with higher-quality electrode products.
