Electrostatic assembly of mesoporous Li4Ti5O12/graphene hybrid as high-rate anode materials

Mesoporous Li4Ti5O12/graphene hybrid was synthesized by an electrostatic assembly method to serve as the high rate anode material for lithium batteries. The graphene sheets were strongly attatched with Li4Ti5O12 spheres and thus can form an efficient electrically conducting network permeating in the electrode to speed the charge and discharge process. The discharge capacity of Li4Ti5O12/graphene hybrid was improved to 124 mAh g−1 at 20 C-rate, which is more than twice the value of the Li4Ti5O12 electrode.
