KAIST extends lifespan of anode-free EV batteries

Researchers at KAIST tackled dendrite growth in anode-free lithium batteries using semiconductor lithography: 300 nm-wide, 150 nm-tall microtubes on copper foil quadruple the lithium deposition area. A 10 nm MXene coating promotes a LiF-rich protective layer. The approach could enable smaller, lighter EV batteries with longer range.

• 300 nm microtubes on copper foil quadruple the lithium deposition area
• A 10 nm MXene coating promotes a LiF-rich protective layer
• The SSL-based method adds no significant weight or thickness to the cell
• The project was led by KAIST professors Jinwoo Lee and Hee-Tae Jung
