A nanospike hybrid carbon black product includes a plurality of carbon black aggregates. Each of the carbon black aggregates has a surface with a plurality of carbon nanospike formed thereon. The carbon nanospikes may each have a length between about 5 nm and 100 nm, and a width between about 5 nm and about 50 nm. A method for manufacturing the nanospike hybrid carbon black product includes the steps of injecting a primary carbon feedstock into a carbon black reactor, and combusting the carbon feedstock under a predetermined high temperature in the carbon black reactor to form carbon black aggregates. A catalyst is then deposited on surfaces of the carbon black aggregates. A secondary carbon feedstock is injected into the carbon black reactor, and reacted with the catalyst to grow carbon nanospikes on the surfaces of the carbon black aggregates.
