In this research, the team delved into the impact of lithium raw material purity on the production and performance of secondary battery cathode materials.

Conventionally, it's assumed that impurities in lithium materials hamper secondary battery performance.

Through their experiments, they demonstrated that utilizing low-purity lithium, not entirely rid of impurities, could reduce secondary battery production costs and carbon dioxide emissions by up to 19.4% and 9.0%, respectively.

Professor Yong-Tae Kim who led the research stated, " Secondary battery cell manufacturers need to reassess whether their current cathode material specifications are too stringent."

The study delves deep into the characteristics and challenges surrounding silicon anode materials -- the focus of significant attention as secondary battery components.
