The honor of the 2020 Nobel Prize in Chemistry went to those who developed lithium-ion rechargeable batteries. These batteries have become an essential energy source for electronic devices ranging from small IT devices to electric vehicles. Tesla, a leading U.S. automaker, recently emphasized the need to establish an innovative production system and reduce battery cost. The price of batteries accounts for a large portion of electric vehicles and cost reduction is vital to popularizing them.
A joint research team, led by Professor Soojin Park and Ph.D. candidate Hye Bin Son of POSTECH's Department of Chemistry with Professor Seungmin Yoo of Ulsan College, has successfully developed a multi-functional separator which allows the batteries to function even when the pouch cell is assembled in ambient air. These findings were introduced in the latest online edition of
