10. Li metal: Novel 3D anode architecture Parallel hollow tubules guide stable plating and stripping of metallic Li via Cobel creep.

Hollow tubules of mixed ionic-electronic conductors (MIEC) at the anode allow for metallic Li to be plated reversibly in a solid-state battery Coble creep mechanism of interfacial diffusion provides stress relief that enables reversible plating The race is on for higher energy density and anode engineering with novel materials and structures offers a path forward for Li metal anodes.
