Abstract Interface instability and safety concerns related to lithium anodes are major barriers the practical use of Li‐CO 2 batteries. To address these challenges, an organic–inorganic dual‐layer protective coating is developed improve Li⁺ transport, provide electronic insulation, isolate CO H O. Deep eutectic solvents (DESs) used as electrolyte additives promote a stable, inorganic solid interphase (SEI) composed Li 3 N, LiF, LiCl, which enhance ionic conductivity, lowers surface energy, suppresses dendrite growth. Additionally, elastic Li‐Nafion buffer layer incorporated mitigate volume expansion during cycling. This dual protection system significantly improves cycling stability, extending lifespan Li||Li batteries by 5.19 4.62 times, respectively, with reversible cycle life 4160 h. A pouch battery using this also demonstrates exbatteryent 1400 h at 50 µA cm −2 cut‐off specific capacity 250 µAh . These findings offer valuable insights for enhancing stability longevity

Abstract Electrocatalytic conversion of carbon dioxide (CO 2 ) into valuable carbon‐based fuels and chemicals represents a promising approach to closing the cycle setting circular economy. Nevertheless, for current electrocatalytic CO reduction reaction (ECO RR) systems, realizing 100% with simultaneously high overall rate (i.e., single‐pass conversion) Faradaic efficiency (FE) remains significant challenge. Enhancing often results in decrease FE, conversely, improving FE may limit rate. Metal–CO (M–CO batteries functions face similar challenges, particularly reversible M–CO batteries, which do not accomplish net because nearly all RR products are reoxidized during subsequent charging process. Such system neutrality poses substantial challenges. This perspective provides an in‐depth analysis state‐of‐the‐art ECO systems alongside main strategies employed address their respective The critical importance achieving both is underscored practical applications effectively close cycle. Furthermore, strategic roadmap that outlines future research directions presented, thereby facilitating advancement comprehensive electroconversion technologies.

Abstract Lithium‐carbon dioxide (Li‐CO₂) batteries have attracted significant attention as a potential solution to mitigate the greenhouse effect and meet demand for high energy density storage systems. Designing efficient cathodic catalysts is crucial development of high‐performance Li‐CO₂ batteries. Herein, an innovative Lewis acidity‐enhancement strategy proposed design in Li‐CO 2 These results demonstrate that metal‐organic framework (MOF) with stronger acidity exhibits significantly lower overpotential 1.27 V, compared 1.58 V MOF weaker acidity. The enhanced Mn3‐MOF accelerates both CO reduction reaction lithium carbonate decomposition, leading improved electrochemical performance, including better rate capability cycling stability. This study emphasizes critical role provides valuable insights
