Title (EN) LITHIUM ION BATTERIES WITH TITANIA/GRAPHENE ANODES
(FR) BATTERIES AUX IONS DE LITHIUM AVEC DES ANODES DE DIOXYDE DE TITANE/GRAPHÈNE
Abstract: front page image
(EN)Lithium ion batteries having an anode comprising at least one graphene layer in electrical communication with titania to form a nanocomposite material, a cathode comprising a lithium olivine structure, and an electrolyte. The graphene layer has a carbon to oxygen ratio of between 15 to 1 and 500 to 1 and a surface area of between 400 and 2630 m2/ g. The nanocomposite material has a specific capacity at least twice that of a titania material without graphene material at a charge/discharge rate greater than about IOC. The olivine structure of the cathode of the lithium ion battery of the present invention is L1MPO4 where M is selected from the group consisting of Fe, Mn, Co, Ni and combinations thereof.
(FR)L'invention concerne des batteries aux ions de lithium ayant une anode comprenant au moins une couche de graphène en communication électrique avec du dioxyde de titane pour former un matériau nanocomposite, une cathode comprenant une structure de lithium olivine et un électrolyte. La couche de graphène a un rapport du carbone à l'oxygène entre 15 à 1 et 500 à 1 et une aire de surface entre 400 et 2630 m2/g. Le matériau nanocomposite a une capacité spécifique d'au moins deux fois celle d'un matériau de dioxyde de titane sans matériau de graphène à une vitesse de charge/décharge plus grande qu'environ IOC. La structure d'olivine de la cathode de la batterie à ions de lithium de la présente invention est LiMPO4 où M est sélectionné parmi le groupe constitué de Fe, Mn, Co, Ni et des combinaisons de ceux-ci.
