Summary: A simple method based on formamide chemistry was developed for the efficient synthesis of 3D flower-like N-doped carbons decorated with highly loaded atomic Fe-N-4 motifs. The introduction of additional ligands in the formamide-derived binary ZnFe-NC resulted in twice as much atomic Fe being loaded, leading to improved electrocatalytic performance for oxygen reduction. Specifically, electrochemical measurements showed that the Bz-promoted synthesized Fe-NC possessed superior onset potential and provided a large specific power in an Al-air battery.

Summary: Molybdenum oxide (MoO3) is an attractive anode material for lithium-ion batteries (LIBs). However, its practical applications are severely limited due to low electrical conductivity, large volume expansion, and slow Li-ion diffusion kinetics. In this study, ultrafine MoO3 nanoparticles (NPs) are synthesized from heavily Mo/N-doped carbonaceous precursors, resulting in MoO3 NPs confined in an N-doped carbon network. This design allows fast electron conduction, short Li-ion diffusion paths, and durable Li-ion storage at high current rates. The results demonstrate the potential of transition metal oxides embedded in conducting carbon networks for practical LIB applications.

Summary: The past 30 years have seen significant advances in lithium-ion batteries, reshaping various aspects of our daily life. However, current Li-ion batteries are unable to meet the growing market demands. To overcome this challenge, it is crucial to understand the fundamentals of battery chemistries and consider both the anode and cathode, as well as their interphases. While previous research has focused on anodes and their solid-electrolyte interphase (SEI), there is a lack of reviews and analysis on the materials and interfacial issues of the cathode side. In this article, we provide a critical overview of the current status and challenges for Li-ion battery cathodes and their solid electrolyte interphase (CEI), discussing their impact on cathode performance characteristics and proposing design guidelines for future Li-ion batteries.
