Cobalt oxide hollow nanoparticles as synthesized by templating a tri-block copolymer micelle with a core–shell–corona structure: a promising anode material for lithium ion batteries

Abstract

Cobalt oxide hollow nanospheres fabricated by core–shell–corona micelle of poly(styrene-<italic>block</italic>-methylacrylate-<italic>block</italic>-ethyleneglycol) in aqueous solution show good electrochemical properties for lithium batteries.
