MXenes, a class of two-dimensional materials, show great potential as anodes but suffer from low intrinsic capacity and severe nanosheet self-stacking. To overcome these issues, this study developed a double transition metal MXene, Ti\n                    <jats:sub>2<\/jats:sub>\n                    NbC\n                    <jats:sub>2<\/jats:sub>\n                    T\n                    <jats:italic>\n                      <jats:sub>x<\/jats:sub>\n                    <\/jats:italic>\n                    , which offers enlarged interlayer spacing and high electrical conductivity.
