Abstract

In this work, we report the electrochemical reactivity of MoTe₂ for various metal ions with special emphasis on Al³⁺ ion storage in aqueous electrolytes for the first time. A stable discharge capacity of 100 mA h g^-1 over 250 cycles at a current density of 1 Ag^-1 could be obtained for the Al³⁺ ion, whereas inferior storage capacities were shown for other metal ions.
