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.

Green Technology for Data Centers: Ultra-low Power 100 Gbps Ethernet Integrated Circuit Developed
A new integrated circuit (IC), consuming only 0.75W of electricity, will reduce the power usage of data chips installed at data centers by one-third.
Each day, billions of people surf the Internet for information, entertainment, and educational content. The Internet contains an immeasurable amount of information and knowledge generated every minute all around the world that is readily available to everyone with a click of a computer mouse. The real magic of the Internet, however, lies in data centers, where hundreds of billions of data are stored and distributed to designated users around the clock.
Today, almost every business or organization either has its own data centers or outsources data center services to a third party. These centers house highly specialized equipment responsible for the support of computers, networks, data storage, and business security. Accordingly, the operational cost of data centers is tremendous because they consume a large amount of electricity.
Data centers can consume up to 100 times more energy than a standard office building. Data center energy consumption doubled from 2000 to 2006, reaching more than 60 billion kilowatt hours per year. If the current usage and technology trends continue, the energy consumption of data centers in the US will reach 8% of the country’s total electric power consumption by 2020.
A research team at the Korea Advanced Institute of Science and Technology (KAIST) and Terasquare, Inc. (
http://www.terasquare.co.kr
), a spin-off company of the university,
developed an extremely low-powered integrated circuit for Ethernet that consumes less than 0.75W of electricity but is able to send and receive data at the high speed of 100 gigabits per second (Gbps). The research team, headed by Hyeon-Min Bae, assistant professor of electrical engineering at KAIST, claims that the new microchip uses only one-third of the electricity consumed by the currently installed chips at data centers, thereby helping the centers to save energy.
Integrated circuits are embedded on communication modules that are inserted into a line card. Data centers have numerous line cards to build a network including routers and switches. Currently, 8W ICs are the most common in the market, and they consume a lot of energy and require the largest modules (112 cm
2
of CFP), decreasing the port density of line cards and, thus, limiting the amount of data transmission.
The ultra-low-power-circuit, 100-gigabit, full-transceiver CDR, is the world’s first solution that can be loaded to the smallest communication modules (20 cm
2
of CFP4 or 16 cm
2
of
QSFP28), the next-generation chips for data centers. Compared with other chip producers, the 100 Gbps CDR is a greener version of the technology that improves the energy efficiency of data centers while maintaining the high speed of data transmission.
Professor Hyeon-Min Bae said, “When we demonstrate our chip in September of this year at one of the leading companies that manufacture optical communication components and systems, they said that our product is two years ahead of those of our competitors. We plan to produce the chip from 2014 and expect that it will lead the 100 Gbps Ethernet IC market, which is expected to grow to USD 1 billion by 2017.”
The commercial model of the IC was first introduced at the 39
th
European Conference and Exhibition on Optical Communication (ECOC), the largest optical communication forum for new results and developments in Europe, held from September 22-26 at ExCeL London, an international exhibition and convention center.
Professor Bae added, “We received positive responses to our ultra-low-power 100-Gbps Ethernet IC at the ECOC. The chip will be used not only for a particular industry but also for many of next-generation, super-high-speed information communications technologies, such as high-speed USB, high-definition multimedia interface (HDMI), and TV interface.”
Before joining KAIST, Hyeon-Min Bae worked for many years at Finisar as a researcher who designed and developed the world’s first super-high-speed circuit, the 100 Gbps Ethernet IC.
