Summary: This study investigates the thermal safety changes and degradation mechanisms of lithium-ion batteries after deep aging under fast charge cycling. Lithium plating is identified as the primary degradation mechanism, which thickens the solid electrolyte interface film, leads to increased impedance and decreased capacity. Aged cells have higher heat generation rates but reduced total heat generation compared to fresh cells. Fast charge cycling reduces the thermal stability of the anode and decreases the triggering temperature for thermal runaway. Additionally, it decreases the lithium plating potential, resulting in advanced side reactions contributing to thermal runaway. The loss of active materials reduces the maximum temperature and maximum temperature rise rate of aged cells.

Summary: In the past decade, the rapid development of lithium-ion battery (LIB) energy storage systems has supported the efficient operation of renewable energy stations. However, the current LIB falls short of meeting the demand for a longer service life. Prelithiation technology has been widely studied to improve the service life of LIBs, and this review summarizes different prelithiation methods. It also analyzes the challenges and potential of large-scale industrialization of prelithiation technology based on industry compatibility, prelithiation efficiency, and energy density. Furthermore, the future trends of LIB improvement using overlithiated cathode materials are discussed.

Summary: Thermal runaway, caused by lithium plating in low-temperature cycling LIBs, is a significant hazard that hinders the application of LIBs in electric vehicles and energy storage systems. This study developed a thermal runaway model that includes the exothermic reaction between metal lithium and electrolyte to account for the aging effect. Validation tests confirmed the effectiveness of the model. The results revealed a three-stage process for thermal runaway and demonstrated that the reaction between plated lithium and electrolyte at around 140 degrees C accelerates the onset of thermal runaway.

Summary: To address the issue of lithium (Li) plating on graphite anodes during fast charging, Li plating regulation and morphology control are proposed. A Li plating-reversible graphite anode is achieved through a localized high-concentration electrolyte (LHCE), resulting in high reversibility and stability. The stable LiF-rich solid electrolyte interphase (SEI) enables a higher average Coulombic efficiency (99.9%) and reversibility of Li plating (99.95%). A self-made LiNi0.5Mn0.3Co0.2O2 | graphite pouch cell exhibits a competitive capacity retention of 84.4% even at high current (7.2 A) after 150 cycles, demonstrating the potential for high-performance fast-charging batteries.

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: This article presents the results of a systematic study on the electrochemical performance and mechanical changes in two types of commercial batteries with different anode chemistry. The study reveals that the swelling of anode layers in batteries with silicon-based components causes deformations in the jelly roll structure, but the presence of a small percentage of silicon does not significantly impact the cycling performance of the cells within the relevant state-of-health range for electric vehicles (EVs). The research suggests that there is room for improving the cell capacities by increasing the silicon loading in composite anodes to meet the increasing demands on EVs.

It was found that blending NMC with LMO can enhance energy density at high rates, with the blend containing 25% LMO showing the best performance. Testing with a special electrochemical setup revealed that the effective current load on each blend component can vary significantly from the nominal rate and also changes with SoC. Operando studies allowed monitoring of the oxidation state evolution and changes in crystal structure, in line with the expected behavior of individual components considering their electrochemical current loads.
