What is Deciphering the electrochemical behavior of Mn-based electrode-electrolyte coupling system toward advanced electrochemical energy storage devices about?
Mn-based aqueous electrochemical energy storage devices (AEESDs) are promising candidates for sustainable and flexible energy applications due to their environmental benignity, high theoretical capacity and versatile architecture. One of the effective strategies to boost their electrochemical performance is to introduce Mn2+ ions into the electrolyte, which can trigger a reversible solid/liquid reaction process of Mn2+/MnO2 deposition/dissolution with a high capacity and an ideal electrochemical kinetics. However, the complex energy storage mechanism that involves the Mn2+/MnO2 deposition/dissolution and the intrinsic insertion/extraction of proton and metal ions remains elusive and poses a great challenge for the rational design of Mn-based AEESDs. Moreover, the insufficient dissolution of MnO2 can lead to the deterioration of performance, which hinders their practical applications. To address these issues, we systematically investigate the Mn2+ ions added Mn-based AEESDs by employing a novel quasi-steady electrochemical measurement technique, and establish a kinetic evolution model to elucidate the solid/liquid reaction at different interface conditions. Furthermore, a full cell
