Summary: Lithium (Li) composites with Li-ionic conductive Al-doped Li7La3Zr2O12 (LLZO) particles (Li/LLZO) are fabricated using a mechanical kneading process. These composites effectively regulate the Li-ion flux and suppress the Li dendritic growth by creating faster pathways for Li-ion migration. As a result, Li-metal-based cells utilizing the Li/LLZO composite anodes demonstrate significantly enhanced cycle stability compared to cells employing pure Li anodes.

Summary: Lithium-ion batteries (LIBs) have emerged as one of the most competitive energy storage technologies, but their tendency to undergo thermal runaway poses serious safety concerns. Early safety warnings for LIBs are essential for their widespread use in power batteries and large-scale energy storage systems. Recent research has shown that hydrogen (H-2) can be generated inside LIBs before thermal runaway occurs, making rapid detection of trace hydrogen the most effective method for early safety warnings. Resistive hydrogen sensors, which can be placed inside LIBs, have attracted attention for their potential application in this regard.

Summary: Li+/Na+ exchange is an effective method for preparing high-performance Mn-based layered cathodes for Li-ion batteries. However, the detailed structural changes during the ion-exchange process are less studied. This study combines in situ synchrotron X-ray diffraction, density functional theory calculations, and electrochemical tests to investigate the structural changes during the ion-exchange process of an Mn-only layered cathode. The findings reveal the thermodynamic favorability of Li+/Na+ exchange and the presence of two tandem topotactic phase transitions.

Summary: The electrochemical Li/Na/K-ion reaction pathways in Ga for high-performance Ga anodes in alkali-ion batteries are thoroughly elucidated using ex situ analytical tools. Ga exhibits a high Li-ion storage reaction, forming Li2Ga, but poor Na- and K-ion storage reactions, forming NaGa4 and K3Ga13, respectively. An amorphous Ga composite (Ga/C) is fabricated, showing high reversible capacity, long-term Li-ion storage stability, and high rate capability. Three-step confinement of amorphous Ga in the composite during cycling is demonstrated as an enhancement mechanism for high-performance Ga/C anodes for LIBs.

Summary: The utilization of ether electrolytes in sodium batteries has been restricted due to oxidation stability concerns. In this study, the use of a 1M NaPF6-diglyme solution on Na3V2(PO4)(2)F-3 polyanionic cathodes is found to form a unique polymer-inorganic cathode-electrolyte-interphase (CEI), resulting in excellent cyclability (96.2% capacity retention after 300 cycles at 0.5C) and outstanding rate capability (124, 120, and 112 mAh g(-1) at 5C, 10C, and 20C, respectively). This peculiar interfacial chemistry may open up new opportunities for high-performance sodium batteries.

Summary: Dual-ion batteries are a viable option for electrochemical energy storage, but the participation of both cations and anions in redox reactions requires the addition of sufficient salt in the electrolyte. To address this, a modified pseudo-2D Doyle-Fuller-Newman model is proposed to simulate the variation of average salt concentration in dual-ion batteries. The model has been validated with experimental data and can help optimize the design of practical dual-ion batteries.

Summary: High-voltage nickel-rich layered cathodes have excellent discharge capacity and high energy density but are structurally and interfacially unstable at high voltages (>4.3 V). By using lithium borate salts as electrolyte additives, an enhanced cathode-electrolyte interphase is generated to improve the stability. Specifically, the use of lithium bis(oxalato)borate (LiBOB) leads to enhanced cycling stability and almost no voltage hysteresis after 200 cycles at 1C.

Summary: There is a growing trend of people spending more time sitting, leading to an increasing number of postural problems. To improve working conditions for workers who spend long hours seated, smart instrumented chairs with warnings of changes in position should be developed. This study proposes a standard office chair instrumentation approach, capable of monitoring physiological parameters such as posture, body temperature, and respiratory frequency, as well as environmental parameters such as temperature, humidity, carbon dioxide levels, noise, and light. The instrumented chair showed 100% accuracy in postural detection and up to 18% error in physiological parameters sensing, making it a potential solution for preventing posture-related pathologies and enhancing work productivity.
