What are some benefits and potential problems that might arise with the use of crab shells to power batteries?

When was the last time you used a lithium ion battery?

Chances are, the laptop you use to complete your schoolwork and the smartphone you use daily contain lithium ion batteries.

These rechargeable, lightweight batteries power everything from electric cars to portable electronics and bicycles.

Despite their widespread use, lithium metal resources are not so widespread and are not finite. Researchers at the Shandong Academy of Medical Sciences in China found a method to convert chitin from crab shells into hard carbon, which can then be used as an anode for sodium-ion batteries. Check out the article below for more information on this exciting new discovery.

1) What are some of the unique properties of lithium that allow it to power such a wide variety of items?

2) What effects do the mining and refining of lithium have on the environment?

3) What are some benefits and potential problems that might arise with the use of crab shells to power batteries?

4) As we look to the future and scientifically evaluate new technologies, should we consider the actual “cleanliness” of new energy sources? Why or why not?
