Опубликована: Май 12, 2023

Abstract Rechargeable lithium‐carbon dioxide (Li–CO 2 ) batteries are promising devices for CO recycling and energy storage. However, thermodynamically stable electrically insulating discharge products (DPs) (e.g., Li 3 deposited at cathodes require rigorous conditions completed decomposition, resulting in large recharge polarization poor battery reversibility. Although progress has been achieved cathode design electrolyte optimization, the significance of DPs is generally underestimated. Therefore, it necessary to revisit role Li–CO boost overall performance. Here, a critical systematic review reported first time. Fundamentals reactions formation decomposition appraised; impacts on performance including overpotential, capacity, stability demonstrated; necessity product management highlighted. Practical situ/operando technologies assessed characterize reaction intermediates corresponding mechanism investigation. Additionally, achievable control measures evidenced provide principles improve Findings from this work will deepen understanding electrochemistry promote practical applications.
