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.
