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

Abstract

A non-aqueous Na-oxygen battery utilizes a gas mixture of CO₂ and O₂ as fuel. The battery exhibits a comparatively high specific energy of 6500-7000 Whkg.sup.-1 over a range of CO₂ 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, Na₂C₂O₄ and Na₂CO₃ as discharge products. The Na--O₂/CO₂ battery provides a promising approach for CO₂ capture and conversion into electrical energy. The Na--O₂/CO₂ 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.
