A new lightweight, three-dimensional structure developed by researchers enhances lithium ion transport in batteries, showing improved stability and energy density, with potential for industrial application.
Just as road signs guide travelers with directions and distances to prevent them from losing their way, “signposts” in certain contexts offer similar guidance. Recently, in the field of chemistry, structures that fulfill a comparable role have been identified, sparking considerable interest in the academic community.in collaboration with Dr. Gyujin Song of Korea Institute of Energy Research and a team of researchers at POSCO N.EX.T HUB have developed a three-dimensional polymeric structure.
This structure is more than five times lighter than the copper collectors typically used in battery anodes and has a high affinity for lithium ions, facilitating their migration through the spaces in the three-dimensional porous structure and enabling uniform lithium electrodeposition. Professor Soojin Park of POSTECH expressed the significance of the research by stating, “This research opens up new possibilities for maximizing the energy density of lithium metal batteries.” Dr. Gyujin Song of the KIER emphasized, “This structure, which combines lightweight properties with high energy density, represents a breakthrough in future battery technology.”
