A group of science researchers at the University of Maryland created crab shell batteries, that is to say, zinc batteries that leverage electrolytes made from crab and shrimp shells. The batteries use chitin, a material found in crustacean shells in abundance, to create a gel electrolyte that is fully biodegradable.
The resulting batteries use this chitosan electrolyte combined with metal zinc components to create a cheap, safe-for-general-use battery. The batteries showed 99.7% energy efficiency retention after 1,000 charge cycles in testing, showing that they are capable of long-term operation. The primary use case for these batteries would be to store excess energy, such as solar and wind-generated energy, for use at a later date.
In addition to being sustainably sourced, the biodegradable nature of the chitosan combined with the recyclable nature of zinc results in an energy storage solution that is fully circular.
