Professor Woo Young Yoon's research lab specializes in advanced energy storage materials, with a primary focus on next-generation batteries such as lithium-metal and lithium-oxygen (Li-O₂) batteries. The lab develops innovative solid polymer electrolytes (SPEs) using sustainable, naturally derived crosslinkers—particularly terpenes—combined with polysiloxane and poly(ethylene glycol) derivatives to enhance ion conductivity, mechanical stability, and dendrite suppression. Their work emphasizes the design of quasi-solid and crosslinked electrolyte systems that improve safety, electrochemical performance, and thermal stability for practical battery applications. The lab also explores the integration of these materials into full-cell configurations to address critical challenges in energy density and cycle life.

Lithium-metal anode has fundamental problems concerning formation and growth of lithium dendrites, which prevents practical applications of next generation of high-capacity lithium-metal batteries. The synergistic combination of solid polymer electrolyte (SPE) crosslinked with naturally occurring terpenes and lithium-powder anode is promising solution to resolve the dendrite issues by substituting conventional liquid electrolyte/separator and lithium-foil anode system. A series of SPEs based on
