Abstract Composite solid‐state electrolytes (CSSEs) that combine the benefits of inorganic and polymer hold great potential for lithium metal batteries (SSLMBs) due to their high ionic conductivity superior mechanical properties. However, overall performance is severely hindered by several practical challenges, including component aggregation, poor interface behavior, limited Li + transport. Here, a unique ultrathin coating triaminopropyl triethoxysilane with bifunctional structure introduced effectively bridges fillers (Li 1+x Al x Ti 2‐x (PO 4 ) 3 , LATP) polyvinylidene fluoride hexafluoropropylene /polyethylene oxide matrix, thereby enabling high‐performance CSSEs (referred as SLPH). This design prevents LATP particle agglomeration, improves interfacial compatibility, ensures enrichment fast transport within SLPH. Consequently, SLPH exhibits low conduction energy barrier ( E = 0.462 eV), desirable (4.19 × 10 −4 S cm −1 at 60 °C), transference number 0.694). As result, SSLMBs SLPH, Li| |Li symmetric cells, LiFePO | coin‐type, pouch demonstrate rate capability long‐time cycling stability. work underscores significance surface functionalization create stable solid‐solid enhance conduction, paving way in SSLMBs.

Abstract Lithium‐ion batteries (LIBs) have been widely adopted in the automotive industry, with an annual global production exceeding 1000 GWh. Despite their success, escalating demand for LIBs has created concerns on supply chain issues related to key elements, such as lithium, cobalt, and nickel. Sodium‐ion (SIBs) are emerging a promising alternative due high abundance low cost of sodium other raw materials. Nevertheless, commercialization SIBs, particularly grid storage applications, faces significant hurdles. This perspective article aims identify critical challenges making SIBs viable from both chemical techno‐economic perspectives. First, brief comparison materials chemistry, working mechanisms, between mainstream LIB systems prospective SIB is provided. The intrinsic regarding stability, capacity utilization, cycle calendar life, safe operation cathode, electrolyte, anode discussed. Furthermore, scalability material production, engineering feasibility, energy‐dense electrode design fabrication illustrated. Finally, pathways listed discussed toward achieving high‐energy‐density, stable, cost‐effective SIBs.

Using Recycled Materials in a Novel Dual Binder System for Hard Carbon Anodes: Closing the Loop Toward Sustainable Li‐/Na‐ion Batteries

Advanced Functional Materials, Год журнала: 2025, Номер unknown

Опубликована: Март 3, 2025

Abstract Hard carbon (HC) has significant potential as anode material for both Li‐ion and Na‐ion batteries; however, its commercialization is hindered by challenges such poor rate capability low initial Coulombic efficiency (ICE). Although polymeric binders constitute a small fraction of the overall electrode composition, they play crucial role in influencing electrochemical performance. Here, this study introduces novel dual composite binder, combining polyacrylic acid (PAA) polyvinyl butyral (PVB). The interaction between COOH groups PAA OH PVB via hydrogen bonding prompts cohesive polymer network resulting electrodes exhibiting superior high ICE laboratory‐scale cells, surpassing performance those with other tested. After optimizing formulations using commercial PVB, we demonstrate first time use recycled sourced from laminated glass waste, to address lack end‐of‐life programs material, which often ends up landfills. Repurposing waste battery applications tackles management issues contributes innovative development advanced, green materials circular economy approach, thus paving way waste‐to‐energy solutions high‐performance socio‐economical environmental benefits.

Trace NaBF₄ Modulated Ultralow‐Concentration Ether Electrolyte for Durable High‐Voltage Sodium‐Ion Batteries

Advanced Functional Materials, Год журнала: 2025, Номер unknown

Опубликована: Янв. 13, 2025

Abstract Ultralow‐concentration ether electrolytes hold great promise for cost‐effective sodium‐ion batteries (SIBs), while their inferior cycle stability under high voltages remains an awkward challenge. Herein, ultralow‐concentration diglyme (G2)‐based with single sodium salt are found to manifest high‐rate capability when employed high‐voltage Na 3 (VOPO 4 ) 2 F (NVOPF) cathode, but specific capacity rapidly depletes exhaustion during long‐term cycling. To address this issue, trace NaBF (0.03 m as electrolyte additive is introduced, which minimally affects ion conductivity of the pristine electrolyte, yet weakens coordination between + ions and G2 molecules. This allows more PF 6 − enter solvation sheath ions, forming a stable cathode interphase enhancing performance without sacrificing (up 20 C). As result, modulated G2‐based enables NVOPF steadily, retention 94.2% over 1000 cycles at low rate 1 C. work provides valuable insights into modulation use in durable SIBs.
