Lithium-carbon dioxide (Li-CO) batteries have garnered significant interest over the past 5 years as next-generation energy storage devices. In this article, we report a nanocomposite of anatase titania nanoparticles (TiO-NPs), carbon nanotubes, and carbon nanofibers as a freestanding gas diffusion cathode for Li-CO batteries. Nanostructured anatase TiO is demonstrated as a low-cost, easy-to-synthesize catalyst for CO capture and utilization. With the developed composite electrode, we confirm the successful reversibility of the carbon dioxide reduction reaction and evolution reaction at the cathode and demonstrate improved Li-CO cell performance through a variety of materials and electrochemical characterization techniques.
在过去的 5 年中，锂-二氧化碳（Li-CO）电池作为下一代储能设备引起了极大的关注。在本文中，我们报告了一种锐钛矿纳米二氧化钛（TiO-NPs）、碳纳米管和碳纤维的纳米复合材料作为 Li-CO 电池的自支撑气体扩散阴极。纳米结构锐钛矿 TiO 被证明是一种低成本、易于合成的催化剂，可用于 CO 的捕获和利用。通过开发的复合电极，我们证实了在阴极上二氧化碳还原反应和演化反应的可逆性，并通过各种材料和电化学特性技术证明了 Li-CO 电池性能的提高。
