Can we survive three minutes without air or three days without water? How about without batteries? Imagine not having a battery for three hours. Lightweight, high-capacity lithium-ion batteries are widely used in mobile phones, laptops, and other necessities in today’s world. However, the organic electrolytes in conventional lithium-ion batteries are highly flammable, leading to fatal fires or explosions. As lithium-ion batteries are widely used in our lives, such accidents can cause direct damage to users, which has led to a demand for a safer battery system.
Professor Soojin Park and Gyujin Song (Post-doc fellow) in the Department of Chemistry and PhD candidate Sangyeop Lee of the Division of Advanced Materials Science at POSTECH together developed a stable aqueous zinc-ion battery that uses water as an electrolyte. They employed a protective polymer layer to prevent electrode…
