Summary: This study focuses on the design and failure analysis of a silicon (Si) anode for lithium-ion batteries (LIBs). The volumetric energy density of the Si anode depends heavily on factors such as Si/C loading, anode calendering density, first-cycle coulombic efficiency, and anode capacity density. Stable Si/C electrode structure is crucial for long-term cycling, and the degree of prelithiation needs to be balanced with cycle life.

Summary: For the application of lithium-ion batteries, thermal management is crucial due to the significant influence of temperature on battery performance. Various mechanisms, including reversible and irreversible losses, affect the thermal behavior of these batteries. Traditional discussions primarily focus on Joule heat and reversible heat caused by entropy, but the losses due to voltage hysteresis become more prominent with the emergence of new active materials like silicon. The research demonstrates the impact of hysteresis losses on common active materials, revealing that the equilibrium potential is not located in the middle between the open-circuit voltage curves. Instead, most of the hysteresis heat is generated during the charging process, which can significantly affect the thermal behavior of lithium-ion batteries. The hysteresis heat generated while charging represents 63% for pure graphite cells and even 75% for silicon-graphite composite cells.

Summary: The silicon suboxide (SiO) anode material shows promise for Lithium-ion batteries (LIBs) due to its high theoretical capacity, but it faces challenges such as large volume change (200%), low electrical conductivity, and low first Coulombic efficiency. A ternary composite ((SiOx/G/SnO2)@C) with a carbon coating layer is developed to address these issues, where graphite as part of the active materials improves Coulombic efficiency and controls volume change, and the carbon coating layer is designed to further restrain the high-volume change of SiOx. With the presence of SnO2, the composite exhibits improved electrochemical performance. Experimental results show that (SiOx/G/SnO2)@C achieves a first charging capacity of 382.6 mAh g(-1) at a current density of 100 mA g(-1), with the Coulombic efficiency improved from 62.2% to 74.9%. After 110 cycles, the capacity reaches 424.6 mAh g(-1) and the capacity retention rate is 103.9%.

Summary: Proton exchange membrane fuel cells (PEMFCs) powered by green hydrogen (H2) are a promising alternative to traditional hydrocarbon-fueled power generators. However, further improvements are needed in efficiency, durability, and low-cost production for widespread adoption. Most strategies to improve PEMFC electrodes utilize single material sets, but anisotropic electrode structures with locally tunable properties may offer enhanced performance due to improved transport.

Summary: Lead glaze with excellent radiation shielding ability can effectively prevent radiation leakage by using lead glazed indoor titles in buildings. However, the low firing temperature of lead glaze is associated with poor wear resistance. In this study, super-hard cBN particles are introduced into the soft glass matrix to improve mechanical properties. Results show that with 5 wt% cBN particles embedded in the glass matrix, the hardness increases by 51.2% and the wear resistance significantly improves.

Summary: This study investigates the effect of trace Cu loading on metal-free catalysts for CO/CO2 reduction reactions (CORR). It is found that increasing Cu loading switches the selectivity from C1 (CH4) to C2 products in CORR. At a Cu loading of 2.5 mu g/cm2, the Faradaic efficiency of CH4 in CORR decreased from 62% to 52% for C2 products. Further increasing the atomic Cu loading to 3.8 mu g/cm2 promotes the Faradaic efficiency of C2 products to 78%. CO2RR requires higher Cu loading than CORR to switch the selectivity from C1 to C2 products. This study clarifies the distinct impact of trace Cu on the activity/selectivity between CORR and CO2RR.

Summary: Dry processing is a promising method for high-performance and low-cost lithium-ion battery manufacturing which uses polytetrafluoroethylene (PTFE) as a binder. The electrochemical stability of PTFE binder in the cathodes and the chemistry of the cathode electrolyte interphase (CEI) layers are studied by cycling the high-loading dry-processed electrodes in electrolytes with LiPF6 or LiClO4 salt. The detection of LiF confirms that PTFE undergoes side reactions in the cathodes, and the thickness of the CEI layer is found to be much thicker when LiPF6 is used as the electrolyte salt compared to LiClO4.

Summary: Dry processing of lithium-ion battery electrodes is considered a promising strategy for manufacturing, but little is known about the impact of dry mixing. This study monitors the degree of dry mixing using dry mixing time and prepares a series of dry-processed electrodes with different degrees of dry mixing. It reveals that the degree of dry mixing significantly affects the morphology, homogeneity of electrode components, and PTFE fiberization, leading to variations in the mechanical strength and electrochemical performance of dry-processed electrodes. It is suggested that a moderate degree of dry mixing is preferred for high-performance dry-processed lithium-ion battery electrodes.

Summary: This study evaluated two commercially available stainless steel mesh substrates (316 SS and 304 SS) as electrodes for oxygen evolution reaction (OER) in natural seawater electrolysis. The results show that 304 SS is less stable against corrosion under neutral and low alkaline seawater electrolytes due to metal dissolution and chlorine evolution reaction (CER), while 316 SS outperforms 304 SS in terms of electrocatalytic activity and corrosion resistance. The performance of 304 SS is comparable to 316 SS under high alkaline seawater electrolyte, where CER and metal dissolution are suppressed by OER.
