Abstract

A novel graphene sheet-wrapped cobalt hydroxide chloride composite (Co₂(OH)₃Cl@GS) is synthesized by a facile one-pot and in situ growth, hydrothermal method, which presents dramatically improved cycling stability and rate capability for long-life lithium ion battery. These exceptional performances are attributed to the introduction of a chlorine group and the extraordinary synergistic effect between Co₂(OH)₃Cl and GS.
