An anode active material comprises a silicon-carbon secondary particle comprising a composite having an exterior conformal carbon coating and formed of type I primary particles. Each type I primary particle comprises a core particle of interconnected silicon, the interconnected silicon formed of nano-sized silicon particles each connected to at least one other particle, inner pores internal to the core particle and defined by the interconnected silicon, an internal carbon coating on internal wall surfaces of the inner pores and a conformal carbon coating on the core particle.
