摘要
本研究报道了袋式锂空气电池的设计及其电化学性能的评价。空气阴极由ketjen black （KB）粉末、Pt/IrO2催化剂和涂覆在碳纸上的粘合剂的混合物组成。在第一部分中，我们对KB:Pt/IrO2电极的电化学性能在硬币电池水平进行了评估，结果表明KB:Pt/IrO2电极在达到最高截止电压（4.5 V）之前进行了300次循环。在硬币电池水平上的优异电化学性能激励我们设计袋式电池。袋状电池的总容量为0.75 mAh，电池可循环465次。对循环袋式实验室进行破坏性物理分析（DPA），通过XRD、SEM和FT-IR分析阴极、阳极和分离器表面的产物，回收的阴极成功地在硬币电池中重复使用。
Design and Demonstration of Pouch-Type Lithium–Air Batteries
The present study reports the design of pouch-type lithium–air batteries (LABs) and the evaluation of their electrochemical performance. The air cathode consists of a mixture of ketjen black (KB) powder, Pt/IrO2 catalyst, and binder coated over carbon paper. In the first part, the electrochemical performance of the KB:Pt/IrO2 electrode was evaluated at the coin-cell level, and the results indicate that the cell with the KB:Pt/IrO2 electrode demonstrated 300 cycles before reaching the upper cutoff voltage (4.5 V). The excellent electrochemical performance at the coin-cell level motivated us to design pouch-type cells. The overall capacity of the pouch cell was 0.75 mAh, and the cell demonstrated 465 cycles. Destructive physical analysis (DPA) was conducted on the cycled pouch-type LABs to analyze the products on the surfaces of the cathode, anode, and separator through XRD, SEM, and FT-IR analyses, and the recovered cathode was successfully reused in coin cells.
期刊介绍：
Energy & Fuels publishes reports of research in the technical area defined by the intersection of the disciplines of chemistry and chemical engineering and the application domain of non-nuclear energy and fuels. This includes research directed at the formation of, exploration for, and production of fossil fuels and biomass; the properties and structure or molecular composition of both raw fuels and refined products; the chemistry involved in the processing and utilization of fuels; fuel cells and their applications; and the analytical and instrumental techniques used in investigations of the foregoing areas.
