Methods of forming carbon-silicon composite material on a current collector

Abstract

Methods of forming electrodes are described. In some embodiments, the method can include providing a current collector. The method can also include providing a first carbon precursor on the current collector and providing a mixture on the first carbon precursor. The mixture can include a second carbon precursor and silicon particles. The method can further include pyrolysing the second carbon precursor to convert the second carbon precursor into one or more types of carbon phases to form a composite material. The one or more types of carbon phases can be a substantially continuous phase with the silicon particles distributed throughout the composite material. The method can also include pyrolysing the first carbon precursor to adhere the composite material to the current collector.
