Using polyoxometalates to enhance the capacity of lithium-oxygen batteries
The Keggin-type polyoxometalate α-SiW12O404- increases the discharge capacity and potential of lithium-oxygen batteries, by facilitating the reduction of O2 to Li2O2, as confirmed by in-situ electrochemical pressure measurements and XRD. Compared to organic redox mediators, polyoxometalates have higher chemical and structural stability, which could lead to longer cycling lithium-oxygen batteries.

Abstract

The Keggin-type polyoxometalate α-SiW12O404- increases the discharge capacity and potential of lithium-oxygen batteries, by facilitating the reduction of O2 to Li2O2, as confirmed by in-situ electrochemical pressure measurements and XRD. Compared to organic redox mediators, polyoxometalates have higher chemical and structural stability, which could lead to longer cycling lithium-oxygen batteries.
