NOVELTY - An anode comprises a carbon shell comprising an outer surface, an inner volume and several pinholes on the outer surface, anode particles arranged in the inner volume of the carbon shell, such that a portion of the inner volume includes void space, and several graphene flakes arranged on the outer surface of the carbon shell and covering at least a portion of the pinholes. USE - Anode used for battery. ADVANTAGE - The anode provides battery having cycle characteristics, reduced coulombic efficiency and capacity. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: production of the anode, which involves applying a sacrificial coating to the anode particles to form coated anode particles, adding an amorphous carbon to the coated anode particles to form particles with an amorphous carbon shell, where the amorphous carbon shell comprises several pinholes and the particles with the amorphous carbons shell suspended in a liquid, dissolving the sacrificial coating to form an electrode with void space suspended in a slurry, and adding several graphene particles to the slurry such that the several graphene particles cover at least a portion of the several pinholes; and a composition, which comprises several carbon shells suspended in a solvent, at least 80% carbon shells including a pinhole, several anode particles suspended in the solvent, such that at least about 80% carbon shells have an anode particle, and several graphene flakes arranged in the solvent such that the several graphene flakes cover at least 80% pinholes on the carbon shells.
