It sounds a bit strange, but it is the result of science. Batteries made from crab could be the alternative of the energy future. The bet is to move towards more efficient ways of storing energy from renewable sources.
The result follows from an investigation carried out by a group of researchers. They found that the shells and exoskeletons of crabs and lobsters have a component that can help. Based on these elements, batteries made of zinc and a biodegradable electrolyte that this crustacean possesses could be manufactured.
The operation of the batteries is simple, they use a liquid, gel or paste to transport ions between the positively or negatively charged poles. For this process, many modern batteries use flammable or corrosive chemicals. If we add to this that the parts made of polypropylene and polycarbonate in lithium batteries take thousands of years to degrade, then the result is a battery with a high environmental impact.

What is chitosan?
Faced with this situation, a component called chitosan appears, but what is this? This is a derivative of chitin found in the cell walls of fungi, the exoskeletons of crustaceans, and the feathers inside squid. With this compound a gel electrolyte is manufactured. The battery resulting from this compound could store energy from wind and solar sources on a large scale.
In the world there is an abundant source of chitosan, which are the exoskeletons of crustaceans (crabs, shrimps and lobsters). The best thing is that they can be easily obtained from shellfish waste.
Making batteries with a biodegradable electrolyte means that two-thirds of the battery could be broken down by microbes. And in the case of this battery, it could break down in just 5 months, leaving only the metal component (zinc) that could be easily recycled. These crab-made batteries are 99.7% efficient after 1,000 battery cycles, making them a viable option for storing wind and solar power for transfer to power grids.
