Abstract
A non-aqueous Na-oxygen battery utilizes a gas mixture of COand Oas fuel. The battery exhibits a comparatively high specific energy of 6500-7000 Whkgover a range of COfeed compositions. The energy density achieved is higher, by 200% to 300%, than obtained with pure oxygen feed. Ex-situ FTIR and XRD analysis confirm Na2O2, NaCOand NaCOas discharge products. The Na—O/CObattery provides a promising approach for COcapture and conversion into electrical energy. The Na—O/CObattery may be extended to other metals. In addition, operation of a metal battery fueled at least in-part by carbon dioxide within an optimal temperature range is considered.
