Abstract ：
The declining performance of aqueous zinc metal batteries (AZMBs) at colder temperatures, especially due to aqueous electrolyte solidification and reduced capacity retention at subzero temperatures, poses a considerable challenge. Here, we report a cheap and ecofriendly aqueous electrolyte formulation comprising low-concentration zinc chloride salt and a common antifreeze agent. We show that the glycerin antifreeze co-solvent effectively interacts with free water molecules and weakens the zinc-ion primary solvation structures, thereby considerably mitigating their detrimental effect at low temperatures. Consequently, the optimized electrolyte successfully outputs a depressed liquid-glass transition point down to -99.2 degrees C and a record-high Zn plating/stripping Coulombic efficiency of similar to 99.94% at -40 degrees C, as well as similar to 70% of its room-temperature capacity at -40 degrees C, opening up a new opportunity for practical AZMBs.

Abstract ：
Lithium metal batteries (LMBs) have garnered considerable interest because of their substantial theoretical capacity. However, their development is hampered due to the grave issue of hazardous lithium dendrites arising from inhomogeneous lithium (Li) electrodeposition. An effective strategy for addressing dendritic growth is to regulate the migration behavior of target molecules and/or ions during cycling. Herein, we demonstrate an in situ self-assembly strategy where metal-organic frameworks (MOFs) grow on a polypropylene separator homogeneously along a certain orientation. By integration of abundant functional groups and secondary structural units, a continuous, uniform, and defect-free distribution of MOFs on the substrate membrane was achieved. The intrinsic subnanochannels of MOFs significantly benefit the transfer of Li+ ions and restrain the chaotic movement of target ions, resulting in a high Li+ migration number (0.86) and enhanced Li+ ionic conductivity. Consequently, a highly stable lithium plating/stripping behavior was observed, leading to efficacious lithium deposition and stable cycling over 1200 h at 2 mAh cm(-2). Additionally, the permselective MOF-based separator with tunable channel sizes promises broad applicability in LMBs. Our approach paves a new pathway for in situ self-assembly strategies for permselective MOF-based separators, which is expected to help develop advanced LMBs with high energy density and long-life performance.

Abstract ：
To realize a low-carbon economy and sustainable energy supply, the development of energy storage devices has aroused intensive attention. Lithium-sulfur (Li-S) batteries are regarded as one of the most promising next-generation battery devices because of their remarkable theoretical energy density, cost-effectiveness, and environmental benignity. However, the practical application of Li-S batteries is hindered by such challenges as low sulfur utilization (< 80%), fast capacity fade, short service life (< 200 redox cycles), and severe self-discharge. The reasons behind the challenges are: (1) low conductivity of the active materials, (2) large volume changes during redox cycling, (3) serious polysulfide shuttling and, (4) lithium-metal anode contamination/corrosion and dendrite formation. Significant achievements have been made to address these problems in the past decade. In this review, the recent advances in material synthesis and technology development are analysed in terms of the electrochemical performance of different Li-S battery components. The critical analysis was conducted based on the merits and shortcomings of the reported work on the issues facing the individual component. A versatile 3D-printing technique is also examined on its practicability for Li-S battery production. The insights on the rational structural design and reasonable parameters for Li-S batteries are highlighted along with the "five 5s" concept from a practical point of view. The remaining challenges are outlined for researchers to devote more efforts on the understanding and commercialization of the devices in terms of the material preparation, cell manufacturing, and characterization.
