New lithium-ion batteries have been invented that have five-times the capacity as current ones opening a new path for the development of batteries used in electric devices such as smart phones and notebooks.
A joint research team that includes Prof. Ji Man Kim of Sungkyunkwan University¡¯s Department of Chemistry and Prof. Won Sub Yoon of the Department of Energy Science discovered that if they use molybdenum oxide combined with a nano constitution to create a cathode, they can increase the capacity of a battery by five times.
The research team was the first to investigate the mechanism of lithium being saved in ¡®metallic cluster¡¯ form in molybdenum oxide. Professor Ji Man Kim said, ¡°The newly discovered mechanism overturned the established theory related to lithium-ion batteries and is the result of several years of experiments and modifications. We can now develop new electrode material for lithium-ion batteries that surpass the limit of the preexisting theory¡±.
The results of the research were published in ¡®Nature Communications¡¯ on March 22, 2016.
