Technology Developed by Research Team Led by Prof. Moon Jun-hyuk

Selected as 'Top 10 Nano-technology of 2018'

 

Prof. Moon Jun-hyuk

 

Spongy nano-tube particle manufacturing technology, developed by Prof. Moon Jun-hyuk's research team, was selected as a 'Top 10 nano-technology' for 2018. This result came from the nano convergence fair, jointly organized by the Ministry of Science and ICT and the Ministry of Trade, Industry, and Energy. These technologies are selected among those recommended as demonstrating tangible outcomes from June 2017 to May 2018.

 

As primary features in this selection, innovativeness (40 points), scalability (40 points), and contribution to R&D (20 points) were evaluated, leaving 20 selected technologies. Next, a thorough review and on-line vote open to members of the Korea Nano Technology Research Society and the Nano Technology Research Association, along with the selection committee, produce the final appointees for the top 10 nano-technologies.

 

Prof. Moon Jun-hyuk's team's efforts produced a designing and manufacturing technology for a sponge nano-tube particle that can absorb the active material in the next generation lithium cell in high density. The active material in the lithium cell is the material that determines the actual amount from the oxidation-reduction reaction in the lithium cell. In a lithium-sulfur cell, the next generation high-capacity lithium cell, sulfur is applied as the active material; generally, sulfur is stored in a porous carbon electrode. However, in this case, due to the high surface energy of sulfur, it is difficult to penetrate the porous carbon.

 

 

Prof. Moon Jun-hyuk's team manufactured a carbon nano-tube particle that includes a nano-pore that it makes it easier for sulfur to get in. This particle is possible for high-volume sulfur to make inroads into the pore and, as a result, the energy density of the cell is two times that of the existing lithium cell. It is expected that, once applied to the next generation of electric cars, fuel efficiency and mileage will be drastically increased.
