Core technology for lithium air secondary battery developed

Will the day come to travel Seoul-Busan with an electronic vehicle? The core technology for lithium air secondary battery, the next generation high capacity battery, has been finally developed.
A research team formed by KAIST Department of Materials Science’s Professors Il-Doo Kim and Seokwoo Jeon, and Kyonggi University Department of Materials Science’s Professor Yong Joon Park has created a ‘lithium air secondary battery,’ with five times greater storage than the lithium-ion secondary battery, by developing a nano fiber-graphene composite catalyst. The research results are published in Aug. 8th online edition of Nano Letters, an academic journal of authority in the nano fields.
A cathode of a lithium-ion battery consists of graphite and an anode of the battery consists of a lithium transition metal oxide. Lithium-ion batteries are widely used in mobile phones and laptops. However, lithium-ion batteries cannot support electric vehicles, providing energy for only 160 kilometers on one full charge. The lithium air secondary battery just developed by the research team uses lithium on the cathode and oxygen on the anode. It is earning the popular acknowledgement among the next generation secondary battery research community for having lightweight mass and high energy density.
