When we sit down for the time honored tradition in Maryland that is a crab feast, we usually throw the shells away. It's something we don't typically think about. But researchers Dr. Lin Xu and his team of researchers [at the Univ. of MD] have discovered a new way to use crustacean shells asa renewable energy.
Xu and his team have been exploring a substance called chitosan. It's found inside the crab shell, that can be used for a zinc-ion battery. And the great part? The battery could last longer, it's safer, and cheaper than the lithium-ion battery.

The Baltimore Sun reported this about 3 weeks ago The link to the article, which may be paywalled, is in the link below. I myself haven't had any crabs since the Sun broke this, but not because of the crab shell/battery connection.
