The sluggish kinetics and mutual interference of oxygen evolution reduction reactions in the air electrode resulted large charge/discharge overpotential low energy efficiency Zn-air batteries. In this work, we designed a breathing air-electrode configuration battery using P-type Ca3 Co4 O9 N-type CaMnO3 as charge discharge thermoelectrocatalysts, respectively. Seebeck voltages generated from thermoelectric effect synergistically compensated overpotentials. carrier migration accumulation on cold surface optimized electronic structure metallic sites thus enhanced their intrinsic catalytic activity. overpotentials were by 101 90 mV, respectively, at temperature gradient 200 °C. displayed remarkable 68.1 %. This work provides an efficient avenue towards utilizing waste heat for improving battery.

Abstract The exploration of sustainable energy utilization requires the implementation advanced electrochemical devices for efficient conversion and storage, which are enabled by usage cost-effective, high-performance electrocatalysts. Currently, heterogeneous atomically dispersed catalysts considered as potential candidates a wide range applications. Compared to conventional catalysts, metal atoms in carbon-based have more unsaturated coordination sites, quantum size effect, strong metal–support interactions, resulting exceptional catalytic activity. Of these, dual-atomic (DACs) attracted extensive attention due additional synergistic effect between two adjacent atoms. DACs advantages full active site exposure, high selectivity, theoretical 100% atom utilization, ability break scaling relationship adsorption free on sites. In this review, we summarize recent research advancement DACs, includes (1) comprehensive understanding synergy atomic pairs; (2) synthesis DACs; (3) characterization methods, especially aberration-corrected scanning transmission electron microscopy synchrotron spectroscopy; (4) energy-related last part focuses great catalysis small molecules, such oxygen reduction reaction, CO 2 hydrogen evolution N reaction. future challenges opportunities also raised prospective section.

Zinc-air batteries (ZABs) are promising energy storage systems because of high theoretical density, safety, low cost, and abundance zinc. However, the slow multi-step reaction oxygen heavy reliance on noble-metal catalysts hinder practical applications ZABs. Therefore, feasible advanced non-noble-metal electrocatalysts for air cathodes need to be identified promote catalytic reaction. In this review, we initially introduced advancement ZABs in past two decades provided an overview key developments field. Then, discussed working mechanism design bifunctional from perspective morphology design, crystal structure tuning, interface strategy, atomic engineering. We also included studies, machine learning, characterization technologies provide a comprehensive understanding structure-performance relationship pathways redox reactions. Finally, challenges prospects related designing
