Sodium ion intercalation and multi redox behavior of a Keggin type polyoxometalate during [PMo<sub>10</sub>V<sub>2</sub>O<sub>40</sub>]<sup>5−</sup>to [PMo<sub>10</sub>V<sub>2</sub>O<sub>40</sub>]<sup>27−</sup>as a cathode material for Na-ion rechargeable batteries

Abstract
The versatile property of the Keggin type POM is the multi-electron transfer that happens during the switching between [PMo<sub>10</sub>V<sub>2</sub>O<sub>40</sub>]<sup>5−</sup>to [PMo<sub>10</sub>V<sub>2</sub>O<sub>40</sub>]<sup>27−</sup>. This tunable behavior makes it unique, efficient material as a cathode for Na-ion batteries.
