Aluminum secondary battery using exfoliated transition metal chalcogenide and graphene composite as cathode active material and method for manufacturing of the same

摘要

The present invention relates to an aluminum secondary battery using the exfoliated transition metal chalcogenide and a graphene composite as a positive electrode active material and a manufacturing method thereof. The secondary battery of the present invention and a manufacturing method thereof improve the intercalation-deintercalation of ions by using a composite of exfoliated electric metal chalcogenide and graphene, thereby enhancing the charge and discharge capacity of the aluminum secondary battery.
