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.

Summary: In this study, a dual-functional electrolyte additive, lithium tetrafluoro(fluoromalonato)phosphate (LFMP), was synthesized to improve the thermal stability of LiNi0.8Co0.1Mn0.1O2 (NCM811) cathode and graphite anode materials. LFMP additive showed excellent cyclability, storage performance, and mitigated gas evolution compared to its boron analog, lithium difluoro(fluoromalonato)borate (LFMB). The advantages of LFMP can be attributed to the superior cathode electrolyte interphase (CEI) and solid electrolyte interphase (SEI) layers derived from LFMP, which exhibit strong binding with O-2(center dot-) and weak binding with PF5, and favorable LiF formation.

Summary: Alkali metals (Li, Na, and K) show promise as high-performance rechargeable alkali metal battery anodes due to their high theoretical specific capacity and low electrochemical potential. However, challenges such as high chemical reactivity, uncontrolled dendrite growth, unstable solid electrolyte interphase, and volume expansion during cycling processes hinder their practical application. The introduction of carbon nanotube-based nanomaterials in alkali metal anodes provides a solution to these issues. These nanomaterials with high specific surface area, superior electronic conductivity, and excellent mechanical stability have attracted considerable attention. This review summarizes recent progress on the application of carbon nanotube-based nanomaterials in stable and dendrite-free alkali metal anodes, discusses the merits and issues of alkali metal anodes, as well as their stabilizing strategies, and explores the relationship between synthesis methods, nano- or microstructures, and electrochemical properties of carbon nanotube-based alkali metal anodes. Additionally, advanced characterization technologies on the reaction mechanism of carbon nanotube-based nanomaterials in alkali metal anodes are reviewed. Finally, the challenges and prospects for future study and applications of carbon nanotube-based AMAs in high-performance alkali metal batteries are discussed.

Summary: The construction of a stable cathode electrolyte interphase (CEI) is crucial for improving the NCM811 particle structure and interfacial stability through electrolyte engineering. In He's research, lithium hexamethyldisilazide (LiHMDS) is proposed as an electrolyte additive to facilitate the formation of a stable CEI on the NCM811 cathode surface while eliminating H2O and HF in the electrolyte. This approach enhances the cycling performance of the Li||NCM811 battery to 1000 or 500 cycles with a 4.5 V cut-off voltage at 25 or 60 degrees C.

Summary: Formaldehyde exposure during pregnancy can cause fetal congenital heart disease (CHD). High-throughput sequencing was used to identify the expression profiles of long non-coding RNAs (lncRNAs) in heart tissues of normal and formaldehyde-exposed newborn rats. A total of 763 differentially expressed lncRNAs were identified, and the Ras and hedgehog signaling pathways were identified as important regulatory pathways in CHD caused by formaldehyde exposure. Several upregulated lncRNAs were validated and may provide a reference for diagnosing and treating CHD.

The beam configuration and the Frenet frame are modeled using the second-order approximate function of the beam centerline. The elastic force vector and its tangent stiffness matrix are formulated, and the constraint of adjacent elements is imposed using Lagrange multipliers. The proposed approach is validated through solving benchmark problems of straight and curved beams under different follower loads.
