Gallery: Scientists Use Crab Shells to Make Better Lithium-Ion Batterie...

 

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. The scientists first put a series of shells through a chemical process that turned them into hollow carbon nanotubes. They then 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.

    If one the last paragraph were left off, this would actually be a great article. The poor assumption that the crab shells thrown out by the food industry is all waste is simple and utterly false information. The shells are used for garden compost. Even in landfills, as they break down, they return much needed calcium back to the environment. Please drop the environmental alarmism and keep the article focused.
