Enhanced Catalytic and Interfacial Properties at Cathode and Electrolyte with Nanocomposite Cathode of Ruddlesden-Popper Perovskite and PrNi 0.7 Co 0.3 O 3-Δ in Protonic Ceramic Fuel Cells

Ryo Kitamura, Yuchen Zhang, Eric Yoshida, Minda Zou et autres

Protonic ceramic fuel cell cells (PCFCs) are a promising technology for power generation with flexible fuels (e.g. hydrogen, ammonia and natural gas, etc.) at intermediate temperatures (300–600 °C). However, at these temperatures, the oxygen reduction reaction (ORR) on cathode starts to dominate …

Lithium diffusion-controlled Li-Al alloy negative electrode for all-solid-state battery

Yuju Jeon, Dong Ju Lee, Hongkui Zheng, Sesha Sai Behara et autres

Abstract Metal alloy negative electrodes are promising candidates for lithium all-solid-state batteries due to their high specific capacity and low cost. However, chemo-mechanical degradation and atomic transport limitations in the solid state remain unresolved challenges. Herein, we demonstrate a lithium-aluminum alloy negative …

Gaussian Differential Assessment of Sequential STEM Radiation Damage in Beam-Sensitive Materials

Hongkui Zheng, Hao Wang, Xiwen Chen, Abolfazl Razi et autres

Electron radiation damage presents significant challenges in the characterization of sensitive materials using transmission electron microscopy (TEM), particularly in atomic-resolution high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM) imaging [1]. Despite the use of low-dose approaches, high-energy electron beams can inevitably induce …
