Rechargeable Lithium Sulfur Battery for Greater Battery Capacity
Professor Do Kyung Kim from the Department of Material Science and Engineering and Professor Jang Wook Choi from the Graduate School of EEWS have been featured in the lead story of the renowned nanoscience journal Advanced Materials for their research on the lithium sulfur battery. This new type of battery developed by Professor Kim is expected to have a longer life battery life and [higher] energy density than currently commercial batteries.
With ample energy density up to 2100Wh/kg—almost 5.4 times that of lithium ion batteries—lithium sulfur batteries can withstand the sharp decrease in energy capacity resulting from charging and discharging—which has been considered the inherent limitation of the conventional batteries.
Professor Kim and his research team used one-dimensional, vertical alignment of 75nm tick, 15μm long sulfur nanowires to maximize electric conductivity. Then, to prevent loss of battery life, they carbon-coated each nanowire and prohibited direct contact between the sulfur and electrolyte.
The result was one of the most powerful batteries in terms of both energy performance and density. Compared to conventional batteries which suffer from continuous decrease in energy capacity after being discharged, the lithium sulfur battery maintained 99.2% of its initial capacity after being charged and discharged 300 times and up to 70% even after 1000 times.
Professor Kim claims that his new battery is an important step forward towards a high-performance rechargeable battery which is a vital technology for unmanned vehicles, electric automobiles and energy storage. He hopes that his research can solve the problems of battery-capacity loss and contribute to South Korea’s leading position in battery technology. Professor Kim’s research team has filed applications for one domestic and international patent for their research.

Wearable computer follows suit of smart phones
KAIST hosts “Wearable Computer Competition” in KI Building, Daejeon Campus, on the 7th-8th of November
“Computer that controls smart phones with the movement of facial muscles” and 12 other wearable computers to be presented
As technology transitions to “Wearable Computers,” KAIST is hosting its 9th “Wearable Computer Competition.” The competition will take place over two days, 7th-8th of November, in KI building, on the main Daejeon Campus.
The “wearable computer” is designed to enable users to use the computer whilst moving by limiting its weight and size so that it can be worn as a part of the body and clothing. Wearable computers have been considered the future of information technology (IT) ever since smart phones and other miniaturized IT devices made an appearance.
The “Wearable Computer Competition” has been held since 2005 under the leadership of Professor Hoi-Jun Yoo from the KAIST Department of Electrical Engineering. It is the only competition in the nation where undergraduate students use their unique ideas and newest technology to produce computers that seem to be existed only in sci-fi movies and comic books.
A total of 15 teams out of 70 made the competition and went through a rigorous selection process based on written applications and interviews to enter the final. The teams at the final received USD 1,400 and IT devices including smart phones to produce a wearable computer.
KAIST increased the number of finalists from the last year"s 10 to 15 this year as the wearable computer industry is extending, and there is growing interest in the computer around the world after the launch of Google Glass and Samsung Galaxy Gear.
This year’s entries included a product for quadriplegic patients to control smart phones with the movement of facial muscles, which attracted public interest. The product in the form of a headband can be worn by quadriplegic patients or someone with limited hand movement. The user can activate the product by clenching their molars and move the mouse on the smart phones with the movement of muscles in their face.
Furthermore, a wearable band shaped device that can control smart phones with simple hand movements is also attracting interest. Broad hand movements of the user allows him/her to receive calls and take photos, and handshakes between users control sharing of files. Body communication can be used to protect private information without a password or locking the device.
In addition, gloves and shoes that can sense the user’s movement to play an instrument without the instrument being present; a cane for the blind that converts visual information to tactile; a belt that protects children from sexual crimes; and a game where the user can be Super Mario to play and other practical products are presented.
The chairman of the competition, Professor Yoo said, “As you can see from the launch of Samsung Galaxy Gear, wearable computers will follow smart phones as the leader of IT devices in the next generation.” He continued, “This competition and workshop is an opportunity to increase public interest in wearable computers and serves as a communication platform for experts to view the present and the future of wearable computers.”
The “Wearable Computer Workshop” will be held this year as well. The workshop under the theme of “the present and the future of wearable computers” invited Professor Kyu-Ho Park, Vice President of KAIST, as a keynote speaker to talk on “ubiquitous, fashionable computers.” Moreover, Samsung’s Dong-Jun Geum and the Electronics and Telecommunications Research Institute’s Hyeon-Tae Jeong will lecture on the “trend and direction of progress of wearable devices” and the “technological trend and prospect of industry of wearable computers,” respectively.

The key to Alzheimer disease, PET-MRI made in Korea
Professor Kyu-Sung Cho
- Simultaneous PET-MRI imaging system commercialization technology developed purely from domestic technology - - Inspiring achievement by KAIST, National NanoFab Center, Sogang University, Seoul National University Hospital –
Hopes are high for the potential of producing domestic products in the field of state-of-the-art medical imaging equipment that used to rely on imported products.
The joint research team (KAIST, Sogang University and Seoul National University) with KAIST Department of Nuclear and Quantum Engineering Professor Kyu-Sung Cho in charge, together with National Nanofab Institution (NNFC; Director Jae-Young Lee), has developed PET-MRI simultaneous imaging system with domestic technology only. The team successfully acquired brain images of 3 volunteers with the newly developed system.
PET-MRI is integrated state-of-the-art medical imaging equipment that combines the advantages of Magnetic Resonance Imaging (MRI) that shows anatomical images of the body and Position Emission Tomography (PET) that analyses cell activity and metabolism. Since the anatomical information and functional information can be seen simultaneously, the device can be used to diagnose early onset Alzheimer’s disease and is essential in biological science research, such as new medicine development.
The existing equipment used to take MRI and PET images separately due to the strong magnetic field generated by MRI and combine the images. Hence, it was time consuming and error-prone due to patient’s movement. There was a need to develop PET that functions within a magnetic field to create a simultaneous imaging system.
The newly developed integral PET-MRI has 3 technical characteristics: 1. PET detector without magnetic interference, 2. PET-MRI integration system, 3.PET-MRI imaging processing.
The PET detector is the most important factor and accounts for half the cost of the whole system. KAIST Professor Cho and NNFC Doctor Woo-Suk Seol’s team successfully developed the Silicon Photomultiplier (amplifies light coming into the radiation detector) that can be used in strong magnetic fields. The developed sensor has a global competitive edge since it optimises semiconductor processing to yield over 95% productivity and around 10% gamma radiation energy resolving power.
Sogang University Department and Electrical Engineering Professor Yong Choi developed cutting edge PET system using a new concept of electric charge signal transmission method and imaging location distinction circuit. The creativity and excellence of the research findings were recognised and hence published on the cover of Medical Physics in June.
Seoul National University Hospital Department of Nuclear Medicine Professor Jae-Sung Lee developed the Silicon Photomultiplier sensor based PET imaging reconstitution programme, MRI imaging based PET imaging revision technology and PET-MRI imaging integration software.
Furthermore, KAIST Department of Electrical Engineering Professor Hyun-Wook Park was responsible for the development of RF Shielding technology that enables simultaneous installation of PET and MRI and using this technology, he developed a head coil for the brain that can be connected to PET for installation.
Based on the technology describe above, the joint research team successfully developed PET-MRI system for brains and acquired PET-MRI integrated brain images from 3 volunteers last June.
In particular, this system has the distinct feature of a detachable PET module and MRI head coil to the existing whole body MRI, so that PET-MRI simultaneous imaging is possible with low installation cost.
Professor Cho said, “We have prepared the foundation of domestic commercial PET and the system has a competitive edge in the global market of PET-MRI system technology.” He continued, “It can reduce the cost of the increasing brain related disease diagnosis, including Alzheimer’s, dramatically.”
Funded by Ministry of Trade, Industry and Energy as an Industrial Foundation Technology Development Project (98 billion won in 7 years), the research applied for over 20 patents and 20 CSI theses.
