Abstract Hard carbon (HC) anodes have shown extraordinary promise for sodium‐ion batteries, but are limited to their poor initial coulombic efficiency (ICE) and low practical specific capacity due the large amount of defects. These defects with oxygen containing groups cause irreversible sites Na + ions. Highly graphited decreases defects, while potentially blocking diffusion paths Therefore, molecular‐level control graphitization hard open accessible channels ions is key achieve...
