Deciphering Polarity Effects of Polymer to Regulate Li+ Ionic Environment in Solid Polymer Electrolytes for Solid‐State Lithium Batteries

open access: yesCarbon Energy, EarlyView.
We elucidate the fundamental influences of polymer polarity on Li+ ionic environments in solid polymer electrolytes by considering four critical components: Li+, FSI−, residual solvents, and polymer matrix. Beyond facilitating LiFSI dissociation and Li+ transport, our findings underscore previously overlooked roles of polymer polarity, thereby ...

Rich‐Electronic Interface Promoting Hydrogen‐Bond Reversible Formation for Ultra‐Stable and Energy‐Efficient Catalytic CO2 Capture

open access: yesCarbon Energy, EarlyView.
Bridging micro–macro scales, a biomass‐derived Ni@C interface creates electron‐rich sites and hydrogen‐bond proton‐relay pathways, tuning interfacial charge and reversible hydrogen bond to enhance carbon capture capacity. Verified by in situ spectroscopy, multi‐scale simulations, and long‐term industrial testing, this system enables low‐temperature and

Weak‐Solvent‐Coordination Inducing MnNCN Preferential Orientation Toward High‐Capacity and Fast‐Charge Lithium‐Ion Storage

open access: yesCarbon Energy, EarlyView.
Preferentially oriented MnNCN nanosheets with high active (003) facets were synthesized by an aqueous weak solvent‐coordination strategy, and highly integrated MnNCN/CNT composite was in‐situ constructed as a high‐capacity fast‐charging anode. NCM811//MnNCN/CNT pouch cell exhibits a high energy density of 325 Wh kg−1 with a long cycle‐life over 200 ...

Multi‐Scale Investigation of Supramolecular Organogels Assembled From Pt(II)‐Salphen Complexes

open access: yesChemistry – A European Journal, EarlyView.
A family of Pt(II)‐salphen complexes with long alkyl chains is investigated as low‐molecular‐weight organogelators. Multi‐scale characterization of their supramolecular gels reveals how the chain length, Pt‐Pt interactions, and π–π stacking direct self‐assembly and tune gel mechanics.
