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−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.

Abstract translation: 非水性Na-氧电池利用CO 2和O 2的气体混合物作为燃料。 在一系列二氧化碳饲料组合物中，该电池具有6500-7000重量％的比能量。 所获得的能量密度比用纯氧气进料高得多，为200％至300％。 原位FTIR和XRD分析证实Na2O2，Na2C2O4和Na2CO3作为放电产物。 Na-O2 / CO2电池为CO2捕获和转换成电能提供了有前途的方法。 Na-O2 / CO2电池可能会扩展到其他金属。 此外，考虑在最佳温度范围内至少部分由二氧化碳燃料的金属电池的操作。
