[EN VIDÉO] Recycling batteries from nuclear waste
Researchers at the University of Bristol have developed a new technique that uses nuclear waste to generate electricity in synthetic diamond cells. When it’s bombarded with beta particles from the decomposition of the carbon-14 that makes it up, it generates an electrical current for thousands of years. Low current, but can be very useful for some applications. (English) © University of Bristol

This nerve Liquidity is Battery. There are those smartphones, connected watchof tablet, wireless accessories and accessories for electric vehicles.All these batteries have one thing in common, they are hard recycle and re-use and components such as lithium, very expensive.In order to solve ecological and cost issues, from Materials Innovation Center Someone from the University of Maryland had the idea of ​​using seashells shellfishin particular CrabCreate the battery.

Why shellfish?because hard shield Crab and other crustaceans including Chitin. It is a biopolymer and is also present in some shells insect even structurally mushroom. it is he who strengthens them Exoskeleton. This transformed substance has also been Chitosan for many application commercial. For example, it is used in the form of diet pills.Actually, it doesn’t really work, but these pills still have the advantage of being able to reduce adverse effects cholesterol. As for the battery, by dipping chitosan into aqueous solution ofacid acetic acid, which scientists have converted into freeze. is this special gel mixed with Zinc Can be used as battery electrolyte.

Biodegradable within five months

In their experiments, the researchers were able to observe that using this type of mixed electrolyte, the energy efficiency of the battery remained at 99.7% even after 1000 discharge-charge cycles, i.e. period The prototype accumulated 400 hours of use. so much performance.

On the ecological side, they also note that the battery can Biodegradable Almost completely after five months. Only zinc residues that can be recycled are left.As already reported, the same type of experiment has been tested with a stack of paper Futura.

In this case, the cells were fully biodegraded within a month. But these crustacean-powered batteries also have other assets. they don’t overheat, ignite No, and there is no risk of explosion.Finally, where they’re not made from lobster shells, they’re much less expensive to produce than Lithium Ion Battery. As Hu Liangbing, director of the Mylance University Research Center, stated in his communicatedchitosan can be simply obtained from waste The overlooked seafood on our table.
