Investigation of reversible metal ion (Li+, Na+, Mg2+, Al3+) insertion in MoTe2 for rechargeable aqueous batteries

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.

Automated summary

In this study, the electrochemical reactivity of MoTe2 for various metal ions was investigated. The storage of Al3+ ion in aqueous electrolytes was focused on and a stable discharge capacity of 100 mA h g(-1) over 250 cycles at a current density of 1 Ag-1 was achieved. However, inferior storage capacities were observed for other metal ions.
