Graphene and diglyme assisted improved Al3+ ion storage in MoO3 nanorod: steps for high-performance aqueous aluminum-ion battery

An approach to improve the Al3+ ion storage capacity of MoO3 in aqueous electrolyte is illustrated here. Graphene as conductive additive and diglyme as electrolyte additive play a pivotal and synergistic role in the improvement. Graphene-MoO3 composite exhibits stable capacity of 160 mAh g−1 over 100 cycles in diglyme mixed aqueous electrolyte with v/v mixing ratio of 50:50, whereas it delivers a capacity of only 75 mAh g−1 at the 100th cycle in pristine aqueous electrolyte. Besides, pristine MoO3 also demonstrates improved stability in diglyme mixed aqueous electrolyte.
