Abstract In the realm of energy conversion and storage devices, transition metal porous oxide composites have been subject extensive research interest. Supercapacitors electrocatalysis, as two important modalities, exhibit a competitive yet balanced relationship, much like state equilibrium. this work, comprehensive reduction approach is employed during pyrolysis anionic/cationic doped molecular clusters, specifically [Zn 7 L 6 ( μ 3 ‐OCH ) ]·[CoCl 4 ] (where = 2‐methoxy‐6‐((methylimino)‐methyl)phenolate, abbreviated Zn Co 1 ). Notably, within an inert atmosphere, significant quantity diverse range reducing gases are generated throughout entire temperature spectrum , monitored by thermogravimetry‐mass spectrometry (TG‐MS). It observed that production these led to in valence oxides, thereby inducing shift electrochemical behavior from oxygen evolution supercapacitive performance at different temperatures. The ‐350 sample demonstrated reaction (OER) performance, with overpotential 168 mV current density 10 mA·cm −2 . Conversely, ‐700 exhibited excellent capacitance attaining 1406 F·g −1 A·g findings offer novel synthesis clusters electrical capabilities via total strategy.

Abstract The sluggish reaction kinetics and formidable shuttle effect of soluble lithium polysulfides (LiPSs) are thorny problems for the future industrialization lithium–sulfur (Li–S) batteries. Therefore, exploring efficient electrocatalysts to capture LiPSs accelerate their conversion is highly desirable yet tremendously challenging. Herein, a high‐efficiency Bi/Bi 2 O 3 /VMoN@rGO electrocatalyst with multifunctional active sites multilevel heterointerfaces elaborately designed Li–S Noteworthy, can greatly modulate electron distribution, facilitate charge transfer, optimize chemical absorption, enhance intrinsic activity, while rGO contributes high electrical conductivity, sufficient sites, robust structural stability. Thanks synergy different components, batteries employing functional separators exhibit impressive electrochemical performance sulfur utilization even under loading. More importantly, it discovered that Bi experience an phase evolution generate S amorphous crystalline phases, thereby bringing in unexpected enhancement. Furthermore, experimental results theoretical calculations authenticate reduced Li decomposition energy barrier achieved after situ reconstruction. This work not only provides new mechanistic insights into developing but also sheds light on regulating catalytic activity via self‐reconstruction.

Abstract The uncontrolled polysulfide shuttling and lithium dendrite growth greatly impede the practical implementation of Li–S batteries. These issues can be alleviated by constructing an artificial layer that immobilizes soluble polysulfides regulates Li + flux. Here, a layer‐expanded montmorillonite is fabricated through molecular intercalation to serve as dual regulator for lithiophilic montmorillonite, with its ordered expanded diffusion channels, exhibits high transference number, promotes homogeneous deposition. Additionally, moderate adsorption polysulfides, combined favorable behavior, enhanced redox kinetics sulfur species. This unique structure enables prolonged lifespan 1000 cycles at 0.5C low capacity decay 0.04% per cycle

Its 2.89 times 2.04 higher than those remelted respectively, demonstrating excellent resistance. This can be attributed to comprehensive effect various factors, such as dual phases, dense structure, passivation film.
