Titanium niobium oxides (TNO) are promising anode materials for sodium-ion batteries (SIBs) due to their efficient ion diffusion channels. However, their poor electronic conductivity and severe volume expansion during Na+ (de-)intercalation impede the longevity of SIBs. To address these issues, the core@shell TiNb0.8O4/C@C microspheres (TNO/C@C) have been developed to enhance electron conduction and Na+ diffusion. The TNO/C@C, featuring a dual conductive configuration, outperforms pure TNO and other variations like TNO/C and TNO@C that rely solely on either bulk or surface electronic conductors. Thus, the TNO/C@C anode material achieves a fast-charging rate of 200 C, allowing full charging in 2 seconds, and demonstrates long-term stability over 5000 cycles. In-situ Raman analysis reveals a zero-strain feature during sodiation/desodiation, which minimizes structural degradation over repeated cycles. In-situ EIS test indicates low electron resistance, enhancing both the rate capability and stability. Therefore, the bulk and surface dual conducting strategy offers new insights into robust and fast-charging SIBs. © 2024, The Authors. All rights reserved.
