Abstract
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.
