A shaddock‐peel‐derived hard carbon with the different thickness of the disordered turbostratic nanodomains (DTN) is achieved through a hydrothermal process followed by a carbonization process. This process leads to different thickness of the DTN ( T D ) in hard carbon with controlled performance in sodium‐ion batteries (SIBs), exhibiting a high initial charge capacity of 287.3 mAh g −1 with T D of 7.3 nm. Further research reveals the controlled T D could greatly affect the balance of the charge conductivity, the sodium‐ion diffusion rate, and the adsorption number at defective sites, which are essential for the electrochemical performance of the hard carbon in SIBs. Controlling T D in hard carbon materials could provide new insights for the structural design of hard carbon derived from biomass for SIBs.
