Summary: Magnesium-sulfur (Mg-S) batteries have the potential to replace lithium-ion batteries due to their high energy density, low costs, and high safety. However, the dissolution and shuttle effect of magnesium polysulfides (Mg-PSs) pose challenges to the large-scale practical application of Mg-S batteries. Efforts have been made to modify separators and develop gel polymer electrolytes to suppress the shuttle effect of Mg-PSs. Further research on separator design is proposed to accelerate the development of Mg-S battery technology.

Summary: In this study, the effect of different metal valences in cobalt-based organic framework compounds on the sulfur reaction kinetics in lithium-sulfur batteries was investigated. Two organic framework compounds, Co-ZIF and CoTBP(III), were constructed as functional intercalation separators and their effects on improving the reaction kinetics of polysulfides and inhibiting the shuttle effect were explored. Experiments and theoretical calculations showed that Co-II exhibited the best catalytic activity, attributed to its strong adsorption energy for polysulfides and higher Fermi level compared to Co-III. The Co-ZIF catalytic layer achieved a discharge specific capacity of 772.7 mAhg(-1) at a high current density of 5C, with an attenuation rate of 0.092% per cycle after 720 cycles and coulombic efficiency above 92%.

Experiments and theoretical calculations showed that Co-II exhibited the best catalytic activity, mainly due to its strong adsorption energy for polysulfides and higher Fermi level compared to Co-III. The discharge specific capacity of Co-ZIF as the catalytic layer of LSBs reached 772.7 mAh g(-1) at a high current density of 5 C, with a cycle attenuation rate of only 0.092% and a coulombic efficiency above 92% after 720 cycles.

Summary: The direct recycling of degraded NCM (LiNi0.5Co0.2Mn0.3O2) cathode materials from spent lithium-ion batteries is more environmentally and economically attractive than present metallurgical treatments. A two-step method is designed to recycle the degraded NCM materials by utilizing aluminum impurity from the attached current collector to compensate for transition metal vacancies and restore the structure. This regeneration protocol simplifies the industrial recycling process and produces high-quality NCM materials with excellent electrochemical performance.

Summary: A strategy for constructing a robust interphase layer using an unsaturated imidazole-based ionic liquid additive ([Vmim1O2][TFSI]) is proposed to stabilize high-voltage Li-rich Li-metal batteries. The ionic liquid with a vinyl group preferentially adsorbs on both the cathode and anode surface, suppressing transition metal ion dissolution and mitigating structural degradation of the electrode. Experimental results show that the Li-metal anode with [Vmim1O2][TFSI]-based electrolyte exhibits stable Li plating/stripping over 750 h, and the full cells with Li1.170Ni0.265Co0.047Mn0.517O2 cathode demonstrate long-term cyclicity with a capacity retention of 87.89% after 350 cycles at 4.8 V.

Summary: The rapid growth of renewable energy poses challenges for energy storage technology. Rankine-based Carnot batteries are considered promising due to their high energy density at low temperatures. This study compares three Rankine-based Carnot Battery systems using a heat pump-organic Rankine cycle and finds that the reversible heat pump-organic Rankine cycle performs better in terms of energy and exergy efficiency, as well as levelized cost of storage. The sensitivity analysis demonstrates that the heat source temperature has a significant impact on the reversible heat pump-organic Rankine cycle using a dual-function machine.

Summary: This study proposes a novel Nafion/PVDF/LLZTO ion exchange membrane (IEM) with high ion conductivity and mechanical properties. The optimized IEM has an ionic conductivity of 0.29 mS cm(-1). Experimental and density functional theory (DFT) calculations suggest that the complementary effect between inorganic ceramic fillers LLZTO and polymer materials favors the generation of new Li+ migration expressway and dehydrofluorination. The H-bonding interactions successfully address the poor mechanical strength issues. Moreover, the sandwich-like structure by commercialized PE buffer layer improves stability and effectively suppresses the membrane swelling effect in organic electrolyte. Consequently, assembled slurry pouch cells containing PE/NPL3/PE membrane exhibit extraordinary performance.

Summary: Single-crystal-to-single-crystal (SCSC) phase transformation is essential for the controllable synthesis of advanced materials. However, understanding the atomic-scale mechanisms during SCSC transformation remains a challenge due to the lack of direct experimental probes. In this study, using in-situ transmission electron microscopy, the nucleation and growth mechanisms of a hexagonal phase in a monoclinic matrix during a heating-induced structural transformation were observed. The findings provide crucial insights into the microscopic mechanisms and kinetics of solid-state phase transitions.
