Summary: Lithium iron phosphate (LiFePO4, LFP) was investigated as an additive in the cathode of lithium-sulfur (Li-S) batteries, which showed improved sulfur utilization and cycling performance. LFP was found to attract polysulfides, reducing the shuttle effect. Postmortem characterization revealed dynamic reconstruction of LFP during cycling, which could have contributed to the observed performance.

Carbon microfiber (CMFs) and carbon nanotubes (CNTs) are introduced to improve the kinetics of thick electrodes. By synthesizing self-supportive integrated thick electrodes with dual hierarchical carbon skeleton of CMFs and CNTs, and TiO2, the optimized electrode achieves high reversible areal capacity, attractive rate performance, and impressive cyclic stability. The enhanced performance is attributed to the interconnected hierarchical carbon architecture and synergistic effect between the individual materials.

By using commercial nickel foam (NF) to develop a monolithic 3D anode with rich in situ heterogeneous interfaces (Cu3P-Ni2P-NiO, denoted NF-CNNOP), the adhesive force of the active materials on NF is reinforced and additional capacity is contributed to the electrode. The enhanced Li-ion storage capability is attributed to the in situ interfacial engineering within the NiO, Ni2P, and Cu3P and the 3D consecutive electron conductive network.

Summary: In this study, a method for directly selectively leaching lithium from industrial-grade waste lithium-ion battery (LIB) black mass is proposed. The results showed that the leaching efficiency of lithium exceeded 97%, while other metals remained below 1%. The alkaline post-leaching solution can avoid the neutralizing stage before the precipitation of lithium salts. This highly efficient leaching strategy offers a broadly applicable approach to reclaiming critical energy minerals from wasted LIBs.

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: 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.

Summary: In this study, the influence of transition metal doping on the electronic and mechanical properties and electrochemical performance of 2HMoS2/NC was investigated using Cobalt (Co) as an example. Co doping was found to effectively improve the electronic conductivity and active site areas of 2H-MoS2/NC at different positions, optimizing the adsorption and diffusion capability of potassium ions. Furthermore, the study revealed the optimal roles of different types of nitrogen atoms in kinetic adsorption, diffusion, and interfacial stability of potassium ions. These findings provide guidance for the experimental design of high rate 2H-MoS2/NC electrode materials and the optimal design of other functional composite materials.

It is found that previously mesostructured, surfactant-free mixtures can produce porous polymers of different morphologies, while unstructured, oil-rich regions lead to solid, transparent polymers without nanostructured morphologies. Additionally, a surfactant-based reference system shows similar phase behavior and polymer morphologies as the comparable surfactant-free system, indicating the importance of the hydrotropic behavior of HEMA in this system.
