Abstract Zinc‐iodine (Zn‐I 2 ) batteries are deemed as promising next‐generation energy storage devices in view of immanent security and high capacity. Nevertheless, their applications deteriorated by unruly dendritic Zn growth, severe polyiodide diffusion, sluggish iodine redox kinetics. Herein, MXene‐mediated Janus separators with heterogeneous double‐sided interfaces designed to simultaneously manipulate deposition accelerate adsorption‐conversion The anode side is composed zincophilic Cu‐modified hollow MXene spheres, which not only decreases nucleation barrier but also suppresses dendrite growth homogenizing electric field distribution inducing oriented aspectant dendrite‐free between the separator anode. While cathode side, consisting iodophilic Co‐modified N‐doped inhibits shuttling promotes electrocatalytic conversion through Co‐N‐C sites. Such an ingenious engineering achieves a durable circulation over 2900 h for Zn||Zn symmetric cells brings about ultrahigh capacity 274 mAh g −1 Zn‐I well ignorable decay (0.001% per circle) after 20 000 cycles. concept design integrating interfacial chemistry regulation physical structure optimization this work provides inspiration constructing advanced exceptional overall performance.

ABSTRACT Carbon electrocatalyst materials based on lignocellulosic biomass with multi‐components, various dimensions, high carbon content, and hierarchical morphology structures have gained great popularity in electrocatalytic applications recently. Due to the catalytic deficiency of neutral atoms, usage single lignocellulosic‐based electrocatalysis involving energy storage conversion presents unsatisfactory applicability. However, atomic‐level modulation lignocellulose‐based can optimize electronic structures, charge separation, transfer processes, so forth, which results substantially enhanced performance carbon‐based catalysts. This paper reviews recent advances rational design as electrocatalysts from an perspective, such self/external heteroatom doping metal modification. Then, through systematic discussion principles reaction mechanisms catalysts, prepared catalysts rechargeable batteries are reviewed. Finally, challenges improving prospects diverse review contributes synthesis strategy via modulation, turn promotes lignocellulose valorization for conversion.

Phloroglucinol–2,6‐Diaminoanthraquinone as a Durable Redox Mediator for Enhancing Conversion Reaction Kinetics in Lithium‐Sulfur Batteries

Advanced Functional Materials, Год журнала: 2024, Номер unknown

Опубликована: Июнь 4, 2024

Abstract Lithium‐sulfur batteries, despite being a promising solution for next‐generation secondary require substantial efforts to overcome the challenges of sluggish sulfur redox kinetics, polysulfides shuttling, and Li metal instability before achieving practical viability. Conventional strategies that utilize catalysts or soluble mediators (RMs) are limited by either impractical producing processes unsatisfactory service life. Herein, an electrochemically active organic material, phloroglucinol – 2,6‐diaminoanthraquinone (PG‐DAAQ) is synthesized through green facile polymerization process better resolve these issues. Serving as RM at cathode, PG‐DAAQ exhibits enduring activity within operating potential window, leading enhanced kinetics utilization. Remarkably, even without any elements, excellent affinity polysulfides, thereby suppressing shuttling facilitating formation more favorable solid‐electrolyte interface stabilize deposition anode. As result, Li‐S cells employing show significantly cycling rate performances than control cells. Even with low electrolyte‐to‐sulfur ratio 6, pouch deliver reversible discharge capacity 821 mA h g −1 after 100 cycles C/10 rate.

Due to its low cost, environmental friendliness and high energy density, the lithium-sulfur battery (LSB) has been regarded as a promising alternative for next generation of rechargeable systems. However, practical application LSB is seriously hampered by short cycle life self-charge owing apparent shuttle effect soluble lithium polysulfides. Using MgSO4@MgO composite both template dopant, template-guided S-doped mesoporous graphene (SMG) prepared via fluidized-bed chemical vapor deposition method. As polypropylene (PP) modifier, SMG with specific surface area, abundant structures moderate S doping content offers wealth physical adsorptive sites reduced interfacial contact resistance, thereby restraining serious effects Consequently, configured (MG) host material separator modifier exhibits an enhanced electrochemical performance average capacity 955.64 mA h g-1 at 1C small decay rate 0.109% per cycle. Additionally, density functional theory (DFT) calculation models have rationally constructed demonstrated that doped atoms in possess higher binding polysulfides than MG, indicating SMG/PP can effectively capture forces. This work would provide valuable insight into developing versatile carbon-based LSB.

The electrolyte plays an essential role in the advancement of lithium-sulfur batteries (LSBs), as it not only transports charge carriers but also extensively influences sulfur conversion mechanisms and electrode-electrolyte interphases formed on electrode surface, thereby directly impacting battery performance. However, majority existing electrolytes suffer from incompatibility with either Li anode or cathode. Here, we develop a densely packed ion-cluster (DPIE) through strategic combination weakly solvating solvent inert diluent, resulting self-assembly abundant compact ion-pair aggregates within its structure.
