Amorphous carbon, particularly hard carbon (HC), is widely considered as the most promising anode material for sodium-ion batteries (SIBs) due to its high reversible capacity and cost-effectiveness. However, complex poorly defined structural properties of HC present challenges in understanding underlying sodium storage mechanisms. To facilitate rational design high-performance anodes, a comprehensive correlation between microstructure behavior critical. This Review critically examines interplay features capabilities, focusing on two key factors: pore structure surface functional groups. It begins by outlining fundamental mechanisms HC, followed an in-depth discussion how chemistry influence storage. Finally, strategic insights are provided manipulate these factors optimize performance. aims drive development next-generation anodes support commercialization SIBs.
