Battery Materials Made Using Crab Shells

MTorrice writes "Crab shells usually are just a nuisance that you have to crack and dig through to get the delicious meat inside. But one team of materials scientists thinks the shells could help them fabricate materials for long lasting batteries. The team used the nanostructures (abstract) found in the crustacean shells as templates to make sulfur and silicon electrode materials for lithium-ion batteries. Sulfur or silicon electrodes have a 10-times greater theoretical energy storage capacity than electrodes used in commercial batteries."
