Abstract
Aqueous manganese-ion batteries (AMIBs) are becoming more noticeable because of their excellent theoretical capacity, outstanding safety profile, and cost-effectiveness. However, there aren't many studies on cathode materials appropriate for AMIBs, and the manganese-ion storage mechanisms within these materials have not been thoroughly investigated. Furthermore, the electrochemical performance of existing cathode materials remains suboptimal. Here, Ag0.11V2O5 is designed and synthesized as the cathode material and introduces the combination displacement/intercalation reaction mechanism to the manganese ion storage for the first time. Ag0.11V2O5 demonstrates a capacity retention of 90.3% after 1200 cycles at 5 A g⁻¹ and achieves a high rate performance of 100.01 mAh g⁻¹ at 20 A g⁻¹. This impressive electrochemical performance is attributed to the reaction, which provides more Mn2+ storage sites and generates highly conductive Ag within the electrode. This study presents a novel approach to achieving high-capacity AMIBs.
