Summary: In this study, a 1D pi-d conjugated metal-organic framework (MOF), Ni-MOF-1D, is presented as an efficient sulfur host to overcome the shuttling behavior and sluggish conversion kinetics of intermediate lithium polysulfides (LiPS) in lithium-sulfur batteries (LSBs). Ni-MOF-1D exhibits a remarkable binding strength to trap soluble LiPS species and acts as an effective catalyst for S reduction and Li2S oxidation. The delocalization of electrons in the pi-d system of Ni-MOF-1D provides superior electrical conductivity, leading to excellent performance in LSBs.

Summary: By coating ordered mesoporous Mn2O3 (m-Mn2O3) and highly conductive Super P (SP) on polyethylene (PE) separators, we have designed a multifunctional composite separator to enhance the reversibility and cycling stability of lithium-sulfur batteries (LSBs). The m-Mn2O3 offers fast chemisorption of polysulfides dissolved in electrolyte, and the highly conductive SP physically mitigates the crossover of polysulfides and reversibly reutilizes them during cycling. In practice, the LSB cell assembled with the separator coated with m-Mn2O3 and SP delivers a high reversible capacity of 553 mAh g-1 at a current density of 0.5 C, even after 300 cycles.

Summary: In this study, a ferroelectric decoration layer of BiFeO3 nanoparticles was applied on a commercial separator to construct a polarization field, accelerating Li-ion migratory process and effectively eliminating barren areas near the anode surface. This facilitated dense and smooth nucleation of lithium deposition, resulting in long-term stability and high Coulombic efficiency. The use of BFO/PP separator in Li-S pouch cells also showed significant improvements in specific capacity and capacity decay over cycles, demonstrating the potential for highly practical Li metal batteries.

Summary: Micro-supercapacitors (MSCs) assembled with intersecting nanoflake-built MnO2 NTAs exhibit high energy density, excellent cycling stability, and desirable flexibility due to their large electroactive surface area, structural stability, wettability, and short transport path of ions and electrons. The output voltage and capacitance of the MSCs can be easily controlled by rational interconnection for practical use. This novel strategy for fabricating high-energy and flexible 3D NTA-based MSCs opens up a new avenue for portable and wearable electronic devices.
