  • Patent number: 9510445
    Abstract: In the present invention, a copper electrode having a nanohole structure is prepared by using a polymer substrate in the form of nanopillars in order to avoid fatigue fracture that causes degradation of electrical and mechanical properties of a flexible electrode during repetitive bending of a typical metal electrode. The nanohole structure may annihilate dislocations to suppress the initiation of fracture and may blunt crack tips to delay the propagation of damage. Therefore, the nanohole electrode exhibits very small changes in electrical resistance during a bending fatigue test.

  • Publication number: 20160285095
    Abstract: In the graphene manufacturing method, a graphite oxide is formed from graphite, and then the graphite oxide is treated with a hydrochloric acid. The hydrochloric acid-treated graphite oxide is reduced at temperature of 120° C. or above and 200° C. or below by performing thermal treatment thereto. Since a low-temperature process is used for manufacturing graphene by performing thermal treatment at a relatively low temperature for a short time, this method has great economic feasibility and utilization. Due to a simple composing process and low thermal treatment temperature, graphene may be mass-produced with a low price. In particular, the graphene may be used as a cathode material for a lithium secondary battery, which exhibits a high capacity at a high voltage of 2V or above by reacting with Li, different from an anode material of a lithium secondary battery.
