Title: Carbon dioxide assisted metal-oxygen battery and related method

Abstract

A non-aqueous Na-oxygen battery utilizes a gas mixture of CO 2 and O 2 as fuel. The battery exhibits a comparatively high specific energy of 6500-7000 Whkg.sup.-1 over a range of CO 2 feed 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, Na 2C 2O 4 and Na 2CO 3 as discharge products. The Na--O 2/CO 2 battery provides a promising approach for CO 2 capture and conversion into electrical energy. The Na--O 2/CO 2 battery 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.
