제목 Hydration Effects and Emerging Materials for Divalent Batteries
초록 Divalent batteries, such as Mg and Zn batteries, still linger at the research stage, requiring cathode materials with enhanced performance. The main challenge in developing the cathode materials of divalent batteries is associated with the dual positive charge that induces stronger electrostatic interactions with the host framework, impeding the diffusion of divalent ions. The presence of these positively charged metal ions also imposes a higher dehydration energy penalty when divalent ions pass through the electrode-electrolyte interface, constituting an additional barrier in the overall cell operation.

In this presentation, I would like to briefly the hydration effects in the host cathode and interface between the cathode and electrolytes. Furthermore, the main part of this talk will cover the development background and reaction mechanism of two emerging materials—redox-active organic macrocycle (PQ-Δ) and conductive 2D MOF—which have recently been introduced as aqueous Zn-battery cathode materials. In addition, the role of hydration effects in the PQ-Δ and MOF cathodes will be explained in detail.
