An electrochemical study on LiMn2O4 for Al3+ ion storage in aqueous electrolytes

Herein, we report the possibility of electrochemical Al3+ ion insertion in LiMn2O4 in aqueous electrolytes. LiMn2O4 exhibits a discharge potential plateau of 1.5 V and a discharge capacity of 65 mA h g−1 is achieved at a current rate of 800 mA g−1 at the 75th cycle with the pre-addition of low-valen...

Description
Summary:Herein, we report the possibility of electrochemical Al3+ ion insertion in LiMn2O4 in aqueous electrolytes. LiMn2O4 exhibits a discharge potential plateau of 1.5 V and a discharge capacity of 65 mA h g−1 is achieved at a current rate of 800 mA g−1 at the 75th cycle with the pre-addition of low-valence Mn ions in an aqueous AlCl3 electrolyte.
