This work investigates the effects of nonuniform SoC within thick electrodes using a pseudo-two-dimensional model of LIBs. During fast (dis)charging along a sloping voltage profile, nonuniform Li-ion insertion produced a gradient in electrode potential along the electrode depth, and the resulting mixed potential acted as an additional source of overpotential. In contrast, along a voltage plateau, the gradient of Li-ion insertion was largely preserved throughout the rest period, and the unavoidable nonuniform SoC induced by fast charging did not produce appreciable overpotential, which became more pronounced with increasing electrode thickness and C-rate. The mixed potential thus plays a dual role in thick-electrode LIBs: in sloping open-circuit voltage regions it homogenizes the electrode at the cost of additional overpotential, while in plateau regions it avoids the overpotential penalty but leaves through-thickness gradients unrelaxed, potentially driving mechanical stress. These findings indicate that two-phase electrodes such as LiFePO4 may circumvent mixed-potential overpotential during fast charging of thick electrodes, although the persistent gradients warrant careful consideration of the associated mechanical consequences.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"9 10","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-09-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149146980","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Tunable, eco-friendly organic cathodes offer a promising alternative. In this review, we categorize organic primary batteries into two main groups: carbonyl- and nitro-based systems. Their massive energy density is unlocked when fluoroethylene carbonate (FEC) is added to the electrolyte. FEC triggers an irreversible four-electron reduction for carbonyls and a six-electron reduction for nitro groups. Despite better than inorganic systems in capacity and safety, organics still struggle with low discharge voltages, spontaneous dissolution during storage, capacity drops at high FEC levels, and difficulties in making high-loading electrodes. To overcome these hurdles, future work could focus on targeted molecular redesign, modification of electrolytes and separators, and improvement of electrode processing techniques. Currently, organic primary batteries are still in early-stage research but have already demonstrated comprehensive advantages, offering a new pathway toward safe, high-energy, and green primary batteries.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"9 10","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149146510","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review critically examines the crystal structure, redox mechanisms, degradation pathways, and performance enhancement strategies of lithium-rich NMC cathodes. It discusses the origins of cationic and anionic redox activity, the structural and chemical evolution responsible for performance decay, and recent advances in synthesis, compositional tuning, elemental doping, and surface engineering.

While thick Na foils remain common in laboratory studies, their excessive sodium inventory can overestimate practical energy-density and does not represent manufacturable cell architectures. Thin Na anodes, however, are challenging to fabricate because of sodium's extreme softness, ductility, stickiness, low melting point, chemical reactivity, and unstable interfacial behavior. This review examines thin sodium-metal anodes from a manufacturing perspective, rather than comprehensively revisiting established stabilization strategies. This review first discusses the intrinsic mechanical, chemical, and electrochemical characteristics governing thin-foil processing and cycling. Composite-supported sodium, sodium alloying, and artificial interphase engineering are then evaluated in terms of their contribution to processability and structural stability. Particular emphasis is placed on emerging fabrication routes, including roll-to-roll processing, melt-assisted infiltration, vapor deposition, and cryogenic processing, together with their key scale-up challenges involving atmosphere control, thickness uniformity, inactive mass, interface stability, throughput, and reproducibility. Finally, this review proposes benchmarking criteria and a materials-to-manufacturing framework to distinguish demonstrated laboratory capabilities from prospective scale-up pathways and identify opportunities toward manufacturable, high-energy sodium-metal batteries.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"9 10","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-09-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149206225","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

LNMO cathodes blended with 5 wt% LO exhibit superior cycling performance and improved reversible capacity compared to reference LNMO‖Graphite cells. The addition of 5 wt% LO showed an increase in material level energy density by ~30% after 200 cycles.

Postmortem cross-sectional images of the electrodes showed an increase in measured porosity as well as an increase in the electrode thickness. The continuous cycling of the 4 V manganese redox region of LNMO resulted in an increase in transition metal dissolution due to the excess cyclable lithium provided through the pre-lithiation.

The three-dimensional GO/PVA network features abundant hydrogen-bonded structures, enabling liquid-free proton conduction within this network. The device is fabricated via in situ growth of polyaniline on both sides of a GO/PVA hydrogel, followed by pressurized drying, which generates a well-integrated electrode–electrolyte interface. This monolithic structure facilitates proton transport via the Grotthuss mechanism. Under completely open conditions (no encapsulation), it retains 93.7% of initial capacitance after 768 h storage and 92.6% after 6 months. At 1 mA cm−2 (a fivefold increase from 0.2 mA cm−2), 98.5% capacitance is retained. Benefiting from its liquid-free nature, it achieves 715 mF cm−2 at 1 mA cm−2 and −30 °C after 6 months of storage under these open conditions, preserving 88.7% of its room-temperature capacitance. Pristine and boric acid-modified devices show tensile strengths of 2.8 MPa (221% strain) and 8.8 MPa (164% strain).

MXene, a family of two-dimensional transition metal carbides and nitrides, offers high electrical conductivity, hydrophilic surface functional groups, tunable interlayer spacing, and excellent solution processability. These properties make MXene an ideal building block for functional inks in additive manufacturing. 3D-printing techniques, including 3D direct ink writing, 3D cold-trap environment printing, and 3D microfluidic-assisted printing, enable the construction of hierarchically porous, high surface area, and customized electrode architectures that overcome the limitations of conventional planar electrodes—such as sluggish ion transport, low active material loading, and lithium dendrite growth. The review highlights the application of 3D-printed MXene-based electrodes in lithium-ion, Li metal, Li–S, sodium-ion, and aqueous zinc-ion batteries, demonstrating significantly improved capacity, rate capability, cycling stability, and dendrite suppression. Key strategies include MXene/rGO aerogels for sodium-metal anodes, MXene/polymer composites for zinc anode protection, and MXene/metal oxide heterostructures for Li–S batteries. Despite challenges related to MXene oxidation, ink rheology regulation, and interfacial impedance mismatch, the integration of 3D-printing with MXene offers a transformative route toward next-generation, high-energy, and structurally tailored energy-storage devices.","PeriodicalId":132,"journal":{"name":"Batteries & Supercaps","volume":"9 10","pages":""},"PeriodicalIF":4.5,"publicationDate":"2026-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"149048063","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This approach enables direct and application-relevant comparison of cycle life, interphase resistance, and Coulombic efficiency (CE). Fluoroethylene carbonate shows the most pronounced improvement, more than doubling the state-of-health at 80% capacity retention (SoH80), while maintaining low overpotentials and stable CE, indicating formation of a robust solid electrolyte interphase (SEI). Vinylene carbonate, 1,3,2-dioxathiolane-2,2-dioxide, and succinic anhydride provide moderate improvements, whereas ethoxysilanes mainly stabilize CE without preventing long-term fade. Other additives show no benefit. Differential capacity analysis (dQ/dV) reveals that early additive decomposition, particularly ring-opening reactions of cyclic compounds, correlates with improved performance.
