Application

• Battery Technology: Eggshell-derived electrodes can be used in rechargeable batteries, providing an eco-friendly and cost-effective alternative to traditional lithium-ion batteries.

Description

Researchers at Murdoch University have developed a sustainable battery technology using chicken eggshells as electrodes. The eggshells, rich in calcium carbonate, are baked, crushed, and transformed into efficient power conductors for energy storage systems. This breakthrough offers a safer, cost-effective alternative to traditional lithium-ion batteries, with applications in renewable energy storage. The project also promotes recycling and the use of bio-waste, supporting a circular economy.

Pathway Description:

The process involves using chicken eggshells as electrodes for rechargeable batteries. The eggshells are baked and crushed to alter their chemical composition, enhancing their conductivity. These modified eggshells are then used in aqueous-based energy storage systems, replacing traditional lithium-ion batteries. The process aims to create safer, cost-effective, and sustainable energy storage solutions.
