A new non-aqueous Li–CO/CO₂ battery with the main discharge products being Li₂CO₃ and carbon is introduced for the first time. Our findings demonstrate that with the addition of CO, the components and morphology of the discharge products are skillfully tailored, becoming more uniform, with poorer crystallinity and better conductivity. Thanks to these features, the utilization of a cathode in the Li–CO/CO₂ battery system is increased and the discharge products are more easily decomposed. These positive effects caused by CO endow the Li–CO/CO₂ battery with enhanced electrochemical performances.

针对高度可充电的Li–CO / CO ₂电池量身定制放电产品的成分和形态†

首次引入了一种新的非水Li–CO / CO ₂电池，其主要放电产物为Li ₂ CO ₃和碳。我们的发现表明，通过添加一氧化碳，可以巧妙地调整放电产物的成分和形态，使其变得更均匀，结晶度更差，电导率更高。由于这些特性，Li-CO / CO ₂电池系统中阴极的利用率得到提高，放电产物更易于分解。由CO引起的这些积极影响使Li–CO / CO ₂电池具有增强的电化学性能。
