Claim 0:
1. A method for making a nitrogen doped carbon composite comprising:
grinding an exoskeleton from a crawfish to make a crawfish powder;
washing the crawfish powder with an acid to reduce a mineral content of the crawfish powder;
washing the demineralized crawfish powder with a base to reduce a protein content of the crawfish powder;
contacting the crawfish powder and silicon microparticles to make a mixture;
grinding the mixture to reduce a size of the silicon microparticles to silicon nanoparticles to make a first composite;
carbonizing the first composite to make a nitrogen doped carbon composite, wherein the nitrogen doped carbon composite comprises silicon nanoparticles.
