In 2022, Maryland engineers turned crab-shell chitosan into a zinc-battery electrolyte; after more than 1,000 cycles, the zinc anode still delivered 99.7% coulombic efficiency

Innovative researchers are turning leftover crab shells into essential components for batteries. Packed with chitosan, these shells can create an eco-friendly battery electrolyte that decomposes naturally. This breakthrough presents a green approach to battery waste management while ensuring the new batteries exhibit impressive energy efficiency even after numerous charging cycles. Ultimately, this advancement could play a significant role in meeting future demands for renewable energy storage.
