Scientists Use Crab Shells to Make Better Lithium-Ion Batteries

If you can make a battery out of a piece of citrus, why not a crustacean? Scientists at Stanford University are taking a look at the nanostructure of crab shells to create better lithium-ion batteries. Using the shells themselves, they were able to put the carapaces through chemical processes to create hollow carbon nanotubes. They stuffed these tiny tubes with sulfur and silicon, and tested them as electrodes. They found that not only did the anode and cathode hold a good amount of their charge after several hundred testing cycles, but the crab shells could help form a cheap, renewable base for batteries.
