1. A method of forming a composite material, the method comprising:
providing a mixture comprising a precursor and silicon particles, wherein an average particle size of the silicon particles is greater than 0.5 μm; and
pyrolysing the mixture to convert the precursor into one or more types of carbon phases to form the composite material,
wherein at least one of the one or more types of carbon phases comprises a continuous phase that holds the composite material together such that the silicon particles are distributed throughout the composite material, and
wherein the composite material comprises a material including silicon and carbon between the silicon particles and the one or more types of carbon phases.
