Closed‐Pore Engineering Couples Sodium Confinement and Interfacial Stabilization for Dendrite‐Resistant Hard Carbon Anodes

Hard carbon, a leading anode for sodium‐ion batteries (SIBs), suffers from nonuniform sodium deposition, which causes dendrite growth and compromises safety and cycle life. Here, we report a closed‐pore engineering strategy based on cobalt‐doped hard carbon (CoHC) that couples internal sodium‐cluster confinement wi...
