themobility is the . There are those of smartphones, of the , wireless accessories and those of electric cars. All of these batteries have one thing in common, they are difficult to make and components, such as , they are expensive. To address both ecological and cost concerns, the researchers of the of the University of Maryland in the United States came up with the idea of using the shells of and in particular to create a battery.
Why shellfish? Why theshielding of and other crustaceans . It is a biopolymer that is also found in the shell of some and also in the structure of . It is he who comes to strengthen them . This transformed substance is also already used under the name of for many commercial. It is used, for example, in the form of diet pills. It doesn’t actually work at all, but these pills would still have the benefit of being able to reduce the harm . As for the batteries, it is by modifying the chitosan by dipping it in a from acetic that scientists made it into a . It is this particular gel, mixed with which can act as the battery electrolyte.
Biodegradable in five months
During their experiments, the researchers were able to observe that with this type of mixed electrolyte, the battery had an energy efficiency that was maintained at 99.7%, even after 1,000 cycles of discharge recharging, which is aof use of 400 cumulative hours for this prototype. This is in regards to performance.
As for the ecological aspect, they also noted that the battery couldalmost completely after five months. Only the zinc residues remained which could be recycled. The same type of experiment had already been experimented with a pile of paper, as already reported .
In this case, the cell had completely biodegraded within a month. But these crustacean-animated batteries have other resources as well. They do not overheat,they do not and do not present any risk of explosion. Finally, and provided they are not made with lobster shells, their production cost is much lower than that of . As explained in his book by Liangbing Hu, the director of the research center at Mylance University chitosan can be obtained simply from of neglected seafood on our table.
