Abstract
A composition is provided that includes mesoporous starburst carbon domains. Each of the mesoporous starburst carbon domains is incorporated with particles of metal or metal oxide in an amount of from 40 to 85 total weight percent of the composition. The metal or metal oxide particles can include tin, cobalt, copper, molybdenum, nickel, iron, or ruthenium, or an oxide thereof. The resulting composition when combined with a binder forms a battery electrode. Such a battery electrode operating as an anode in a lithium ion battery has gravimetric capacity of more than 1000 milliampere hours per gram after 15 galvanostatic cycles.
