Summary: | We report the electrochemical intercalation–extraction of aluminum (Al) in the layered TiS2 and spinel-based cubic Cu0.31Ti2S4 as the potential cathode materials for rechargeable Al-ion batteries. The electrochemical characterizations demonstrate the feasibility of reversible Al intercalation in both titanium sulfides with layered TiS2 showing better properties. The crystallographic study sheds light on the possible Al intercalation sites in the titanium sulfides, while the results from galvanostatic intermittent titration indicate that the low Al3+ diffusion coefficients in the sulfide crystal structures are the primary obstacle to facile Al intercalation–extraction. |
