Self-assembly and lithium storage performance of a nanoscale polyoxometalate based on the {MnTa18} cluster

Abstract

A nanosized Ta/W mixed addendum polyoxometalate (Cs12K3H7[MnTa18Si6W54O231]ยท61H2O) based on the unprecedented {MnTa18} cluster was fabricated successfully under hydrothermal conditions. An excellent electrochemical performance of this compound was found in lithium-ion batteries (LIBs) as an anode material. The discharge capacity was 829.9 mA h gโˆ’1 at a current density of 100 mA gโˆ’1 in the first cycle and stable at 428.4 mA h gโˆ’1 after 100 cycles, which suggests the potential application of this new compound in LIBs.
