Abstract
An anode for use in lithium-ion battery. The anode contains silicon nanoparticles, a coating of carbon on the silicon nanoparticles, and a polymeric binder. A method of making an anode for use in lithium-ion battery. The method includes the steps of mixing the silicon nanoparticles with wheat flour to form a homogenized mixture of wheat flour and silicon nanoparticles, heating the homogenized mixture to form a silicon-carbon composite comprising a coating of carbon on the silicon nanoparticles which is then heated along with an additional quantity of wheat flour in an inert atmosphere resulting in an anode comprising silicon-carbon composite with a double coating on the silicon nanoparticles. The silicon-carbon composite is then mixed with a polymeric binder, resulting in an anode for use in a lithium battery. An electrochemical cell with an anode containing silicon nanoparticles, a coating of carbon on the silicon nanoparticles; and a polymeric binder.
