KAIST team uses nanotech to solve vehicle battery problem

Korean scientists have discovered a way to improve the energy output and lifecycle of lithium-ion batteries by applying nanotechnology in the development of lithium manganese oxide for use in cathodes. The materials have been studied over the years as an alternative to lithium cobalt oxide to boost power and life expectancy of rechargeable batteries for electric vehicles. However, the dissolution of manganese during the chemical reaction process to create the compound has shortened the life cycle of lithium-ion batteries.

A team of scientists and researchers led by professor Choi Jang-wook at Korea Advanced Institute of Science and Technology’s Graduate School of Energy, Environment, Water and Sustainability have found a way to deter manganese dissolution. It said that the team was able to realign the atoms in the crystal structure of lithium manganese oxide by applying nano materials, which were able to boost the activity of both manganese and lithium-ion chemical elements.

This process led secondary batteries to generate five times as much power as existing batteries with lithium cobalt oxides, and have three times their life expectancy.
