ITRI (Industrial Technology Research Institute), Taiwan's largest and one of the world's leading high-tech research and development institutions, will accept a "2009 R+D 100 Award in Energy Devices" today, in Orlando, Fla., for developing STOBA (self-terminated oligomers with hyper-branched architecture), the first technology to enhance the safety of lithium-ion (Li-ion) batteries.
"It is a great honor to be recognized by a publication as prestigious and influential as R+D Magazine," said Dr. Alex Peng, senior research scientist and deputy general director at ITRI's Material and Chemical Research Laboratories (MCL). "During the past five years, the STOBA team worked diligently to develop this technology. They have truly earned this achievement."
Li-ion batteries, the power source for many consumer electronic devices, including cell phones, laptops, MP3 players, cameras, and hybrid and electric cars, are susceptible to overheating, which can cause fires and explosions. In the past, safety standards for Li-ion batteries could not be raised because there was no solution available.
To meet the growing demand for high-safety lithium batteries, ITRI successfully developed STOBA, which has fundamentally resolved the safety issue. By integrating a nano-grade high-molecular polymer, which forms a protective film, into the Li-ion battery, a locking effect is generated when the battery encounters excessive heat, external impact or piercing and interrupts the electrical and chemical action, preventing explosions. In 2008 and 2009, STOBA passed the mandatory shorting and piercing experiments conducted by battery manufacturers in Japan and Taiwan. These intensive nail penetration and impact tests confirmed STOBA's effectiveness in preventing internal shorting and overheating in Li-ion batteries.
For the past 47 years, The R+D 100 Awards have annually identified and recognized the 100 most significant and revolutionary technologies newly introduced to the market. Past winning technologies include the printer (1986) and HDTV (1998). An R+D 100 Award serves as a mark of excellence to industry, government and academia and confirms the technology is one of the top innovations of the year. This year's winners will be honored at a ceremony this evening in Orlando, Fla.
