Title:
ALUMINUM SECONDARY BATTERY USING COMPOSITE OF EXFOLIATED TRANSITION METAL CHALCOGENIDE AND GRAPHENE AS POSITIVE ELECTRODE ACTIVE MATERIAL, AND METHOD OF MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2020/045793
Kind Code:
A1
Abstract:
The present invention relates to an aluminum secondary battery using a composite of exfoliated transition metal chalcogenide and graphene as a positive electrode active material, and to a method of manufacturing same. The secondary battery and the method of manufacturing same according to the present invention, by using a composite of exfoliated transition metal chalcogenide and graphene, can improve intercalation-deintercalation of ions, thereby improving the charge/discharge capacity of an aluminum secondary battery.
