摘要
我们开发了所有固态可充电空气电池（SSAB），包括作为负极的烷基醚基取代蒽醌（PE-AQ）、作为固态电解质的质子传导芳香离子膜和基于铂的氧扩散正极。与之前的 SSAB 相比，由于 PE-AQ 的氧化还原电位较低，且优化了负极配置，拟议的 SSAB 显示出更高的开路电压和标称电池电压（分别为 1.1 V 和约 0.70-0.60 V）。库仑效率达到了 97%，并且证实了其卓越的速率特性（100 C 以下为 90%）。在充放电循环过程中，经过 100 次循环后，初始放电容量保留了 82%。
Alkyl-Ether Group-Modified Anthraquinone-Based Negative Electrode for Enhanced Electrochemical Performance of All Solid-State Rechargeable Air Batteries
We developed all solid–state rechargeable air batteries (SSABs) comprising alkyl-ether group-substituted anthraquinone (PE-AQ) as a negative electrode, a proton-conductive aromatic ionomer membrane as a solid electrolyte, and a platinum-based oxygen diffusion positive electrode. Compared with our previous SSABs, the proposed SSAB showed higher open circuit and nominal cell voltages (>1.1 and ca. 0.70–0.60 V, respectively) because of the lower redox potential of the PE-AQ and optimized negative electrode configuration. The Coulombic efficiency was 97%, and superior rate characteristics (>90% up to 100 C) were confirmed. During charge/discharge cycling, 82% of the initial discharge capacity was retained after 100 cycles.
