Increasing mass loading extends transport pathways for both charge carriers, while electrode densification by roll pressing, essential for maximizing gravimetric and volumetric energy density and minimizing electrolyte content, further restricts ion transport in low‐porosity electrodes. Here, graphene mesosponge (GMS) is introduced as a functional conductive additive that tailors electrode microstructure through its sponge‐like mesoporous framework. High‐loading electrodes based on Co‐free, pure‐Ni layered oxides containing only 1 wt.% GMS exhibit enhanced electronic and ionic conductivity, delivering high reversible capacity with reduced polarization. The deformable mesoporous framework of GMS also buffers compressive stress during roll pressing, enabling practical electrode densities above 3.5 g cm −3 without inducing cracking of the active material particles. Digital‐twin analysis reveals that the porous GMS architecture forms a three‐dimensional electron‐ and ion‐transport network, with electrolyte retained within its mesopores facilitating ion transport and resulting in superior rate capability compared with electrodes containing single‐walled carbon nanotubes. These results demonstrate that GMS is a transformative conductive additive for simultaneously improving energy and power densities in practical lithium‐ion batteries through rational microstructural design of dense composite electrodes.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"88 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2026-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149130502","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, four phenothiazine–anthraquinone donor–acceptor polymers are constructed by varying chain architecture, D–A connectivity, and backbone rigidity to elucidate how macromolecular structure regulates bipolar charge storage. The resulting structure–transport relationships reveal that open crosslinked networks improve ion accessibility, whereas direct D–A conjugation within rigid backbones promotes orbital delocalization and charge transfer. These complementary structural features activate both p‐type phenothiazine and n‐type anthraquinone redox centers, enabling reversible co‐storage of AlCl 4 − and AlCl 2+ . Accordingly, the optimized PTZAQ‐C3 delivers a reversible capacity of 243 mAh g −1 , excellent rate capability (122 mAh g −1 at 50.0 A g −1 ), and exceptional cycling stability up to 90,000 cycles. PTZAQ‐C3 also maintains 200 mAh g −1 at −30°C and reaches an areal capacity of 10.08 mAh cm −2 at a mass loading of 50.4 mg cm −2 .

However, while these blends are often discussed in terms of particle‐level properties, the effect of processing conditions, such as calendering, has received less attention, despite their strong influence on electrode microstructure due to the differences in morphology, surface characteristics, and crystallographic density. We investigate here systematically NMC, NMC/LMFP with 70/30 wt.%, and NMC/LMFP with 50/50 wt.% cathodes under uncalendered, moderately‐calendered, and hard‐calendered conditions, employing state‐of‐charge‐dependent rate analysis, full‐cell cycling, electrode‐level transport characterization, and cathode‐level cost‐energy evaluation. NMC tolerates calendering, maintaining rate capability, while showing improved capacity retention over 500 cycles. In contrast, NMC/LMFP blends show a narrower, composition‐dependent calendering limit. The 70/30 blend retains its rate‐capability benefit under no‐to‐moderate calendering, whereas the 50/50 blend is strongly penalized by densification. Hard calendering induces transport‐limited behavior in the blends, eliminating rate benefits and degrading cyclability. Stabilizing the NMC with Nb incorporation further improves cyclability and energy retention of the 70/30 blend, demonstrating a pathway to combine microstructure‐enabled rate capability with improved durability and favorable cathode‐level cost‐energy balance.","PeriodicalId":111,"journal":{"name":"Advanced Energy Materials","volume":"26 1","pages":""},"PeriodicalIF":27.8,"publicationDate":"2026-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149130504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, existing recycling technologies struggle to process mixed feedstocks efficiently and often recover products with limited added value. Here, we advance beyond cathode‐focused hydrometallurgical recycling by integrating composition‐adjustable cathode resynthesis with the purification and surface modification of co‐recovered graphite, followed by full‐pouch‐cell validation and unified process‐level assessment. Mixed low‐nickel cathodes are upgraded to high‐performance LiNi 0.6 Mn 0.2 Co 0.2 O 2 (NMC622) with improved lithium‐ion transport and cycling stability. Meanwhile, a closed‐loop graphite upcycling process produces battery‐grade anodes with enhanced interfacial kinetics and durability. Full pouch cells assembled entirely from the upcycled materials exhibit fewer side reactions and approximately twice the cycle life of cells using commercial counterparts, retaining 70% of their capacity after 2590 cycles. Techno‐economic and life‐cycle analyses further indicate >95% recycled‐material utilization, 22.9% higher profitability, and reductions of 27.0% in greenhouse‐gas emissions and 29.4% in energy consumption relative to the reference recycling route.

Therefore, it is pivotal yet significantly challenging to effectively control Li nucleation and deposition in LMBs. Here, we engineer a Janus Ag nanoskin‐armored polyimide (Ag@PI/PI) bilayer separator by in situ growth Ag nanoparticles on the surface of PI nanofiber and integrating a high‐strength PI nanofiber membrane as the dorsal substrate. Specifically, the Ag nanoskin acts as a three‐dimensional lithiophilic host to seize Li and induce sequential Li nucleation, thereby preventing Li dendrite formation. As a result, the Ag@PI/PI‐Li||Cu cell exhibits a low overpotential of 31.0 mV, high Coulombic efficiency of 98.9%, and prolonged Sand's time of 26.3 h. Significantly, the Ag@PI/PI separator delivers a high Li + transference number (0.70) and exceptional cycling stability (1600 h) in a Li||Li cell. Moreover, the Ag@PI/PI‐based Li||NCM523 cell achieves a remarkable specific capacity of 108.32 mAh g −1 at 5 C while retaining a satisfying capacity retention of 88.7% at 1 C.

However, their practical application is severely limited by drastic volume variation and unstable solid electrolyte interphase (SEI) chemistry. Achieving both mechanical robustness and rapid ion transport within the SEI remains a long‐standing challenge. Herein, trace SbF 3 is doped into the phosphorus‐carbon (P/C) composites through a facile ball‐milling. Taking advantage of the SbF 3 preferential reduction over phosphorus, a hybrid interphase enriched with Li 3 Sb and LiF is in situ formed during initial lithiation. The hybrid interphase effectively suppresses the dissolution and shuttling of polyphosphides, which also integrates fast ionic/electronic transport with enhanced mechanical rigidity, thereby accelerating reaction kinetics. The synergetic effect endows the P/C‐SbF 3 anode with a high retained capacity of 970.10 mAh g −1 after 500 cycles at 1 A g −1 and a superior rate capability of 893.84 mAh g −1 at 15 A g −1 .
