ELECTRODE INCLUDING A GRAPHENE LAYER AND A SELF-ASSEMBLED ELECTRODE ACTIVE MATERIAL AGGREGATE LAYER, AND SECONDARY BATTERY USING SAME, AND METHOD FOR MANUFACTURING SAME

摘要

The present invention relates to: an electrode including a graphene layer, for improving the adhesion properties between a self-assembled electrode active nanoparticle aggregate layer and a collector; a secondary battery including same; an electrochemical capacitor including same; and a method for manufacturing same. More particularly, the graphene layer covers the self-assembled electrode active nano particle aggregate layer, and the graphene layer and the electrode active nano particle aggregate layer form an alternating multilayer so that fast electron transfer is achieved through the graphene layer and lithium ions can move quickly through the empty spaces between the aggregates. Thus, a thin battery suitable for fast charging and discharging can be realized. In particular, mechanical stability can be increased to provide good long lasting characteristics.
