The unsatisfactory conductivity and large volume variation severely handicap the application of SnO2 in sodium‐ion batteries (SIBs). Herein, we design unique three‐layer structured SnO2@C@TiO2 hollow spheres to tackle the above‐mentioned issues. The hollow cavity affords empty space to accommodate t...
