Defect-rich TiO2 interphase and sulfur vacancies boost lithium storage in 3D-printed WS2 anodes
A 3D-printed WS2/TiO2@C anode combining sulfur vacancies and a defect-rich TiO2 interphase delivered markedly higher lithium storage capacity than WS2 or MXene alone. The second half of the strategy lies in the electrode architecture itself. By integrating the interphase-regulated material into a…
