{"title":"Self-healing polymer binders: next-generation battery applications","authors":"Van-Phu Vu, Hye-Mi So, Areum Kim, Jin Young Lee, Minsub Oh, Seungmin Hyun","doi":"10.1039/d5ta04403k","DOIUrl":"https://doi.org/10.1039/d5ta04403k","url":null,"abstract":"Polymer binders are crucial in electrodes, as they both hold together active material particles and conductive additives and firmly bond the composite to the current collector. Thus, they maintain the mechanical integrity of battery systems and stabilize electron pathways during repeated cycling. However, mechanical stresses such as bending, stretching, and volumetric changes can generate internal fractures that disrupt conductive pathways, detach active particles, and compromise electrode–collector interfaces, ultimately degrading electrochemical performance. Although conventional binders provide adequate adhesion and processability, they are inherently passive and cannot respond to such structural damage. Once cracks form or particle contact is lost, they cannot re-establish connectivity, causing irreversible capacity loss. In contrast, self-healing polymer binders (SHPBs), a new class of smart materials, can autonomously repair the mechanical and structural damage incurred during battery operation. Their unique ability to re-establish chemical or physical bonds within the polymer matrix enables them to effectively mend microcracks, preserving electrode cohesion and conductive networks. These adaptive properties offer several compelling advantages, <em>e.g.</em>, improved mechanical resilience and extended cycle life. They also mitigate internal short circuits and potential thermal runaway, enhancing safety. Furthermore, SHPBs support consistent electrochemical performance by maintaining interfacial integrity among active materials, conductive additives, and current collectors. This reduces the need to maintain or replace batteries and/or their components, improving the cost-effectiveness and environmental sustainability of energy storage systems. In contrast to earlier reviews that focused on binders for Si-based lithium-ion batteries, this review explores recent advancements in the molecular design strategies and healing mechanisms of SHPBs, and their impact on cell-level performance across battery platforms such as lithium-ion, lithium–sulfur, and emerging sodium-based batteries. We discuss critical challenges, key future research directions, and opportunities for advancing resilient, safe, high-energy-density batteries with prolonged cycle lives.","PeriodicalId":82,"journal":{"name":"Journal of Materials Chemistry A","volume":"68 1","pages":""},"PeriodicalIF":11.9,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145008993","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, a heterojunction assembly of ternary SnS/Mo2S3/g-C3N4 nanocomposites with varying Sn and Mo weight ratios was synthesized through a single-step hydrothermal method. At an optimized ratio of tin to molybdenum (1 : 2), denoted as SM-3, promising electrochemical and photocatalytic performances were observed compared to bare SnS/g-C3N4 and Mo2S3/g-C3N4. It displayed a maximum specific capacity of 200 C g-1 at a current density of 1.0 A g-1 and the lowest equivalent series resistance among the prepared electrodes, as revealed by electrochemical measurements. For real-time applications, the fabricated device SM-3(+)||activated carbon(-) delivered an energy density of 37.24 Wh kg-1 at a power density of 756 W kg-1 with a capacity retention of 85% for continuous 5000 cycles of charge-discharge. The remarkable energy storage performance was evident by powering a 3 V blue light-emitting diode when three such devices were connected in series. Photocatalytic studies revealed a photoreduction of 95.2% of Cr(VI) (20 mg L-1) to non-toxic Cr(III) and photodegradation of 91% of eosin yellow dye (20 mg L-1) with a minimal catalyst dosage (0.3 g L-1) within 120 min of irradiation through a first-order kinetic process. The negative conduction band potential (-1.21 eV) of SM-3, as estimated by Mott-Schottky analysis, confirmed the involvement of O2˙- radicals and photogenerated electrons in the degradation process, which was further confirmed by radical trapping experiments. Charge carriers followed a double Z-scheme pathway that lowered the recombination rate.","PeriodicalId":92,"journal":{"name":"Nanoscale","volume":"111 1","pages":""},"PeriodicalIF":6.7,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145008758","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Exciton-polaritons, hybrid light-matter quasiparticles, offer a promising platform for investigating SOC in quantum fluids. By utilization of the optical anisotropy of materials, Rashba-Dresselhaus SOC (RDSOC) can be generated, enabling robust polariton spin transport. However, the intrinsic connection between the RDSOC and polariton spin evolution lacks an intuitive interpretation. Here, we demonstrate room-temperature exciton-polaritons with RDSOC in a microcavity containing anisotropic two-dimensional hybrid perovskites. We reveal that the RDSOC arises from geometric phase accumulation during polariton polarization evolution on the Poincaré sphere, which generates an effective gauge field and drives momentum-space spin splitting. By resonantly injecting polaritons, we achieve the generation, separation, and propagation of purer polariton spin states, i.e., a polariton spin Hall effect. Our findings establish geometric phases as the origin of intrinsic RDSOC, paving a feasible avenue for spin-selective control in perovskite-based photonic devices.","PeriodicalId":53,"journal":{"name":"Nano Letters","volume":"53 1","pages":""},"PeriodicalIF":10.8,"publicationDate":"2025-09-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145008911","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}

The V-Hydrogel reserves the glutathione peroxidase-, peroxidase-, catalase-, and oxidase-mimetic enzymatic activities derived from vanadium oxide nanowires, thereby exhibiting efficient tumor-specific catalytic therapy. Simultaneously, the introduction of bactericide THPS endows the potent antibacterial capabilities of V-Hydrogel against surgical site infections. This hydrogel exhibits dynamic mechanical adaptability to the tumor microenvironment (f), ensuring conformal coverage of irregular resection cavities for precise therapy. Additionally, the V-Hydrogel can reprogram the immunosuppressive TME via polarizing macrophages into antitumor M1 phenotypes and recruiting cytotoxic T cells, thereby establishing systemic antitumor immunity.

This evolution in architectural thinking draws inspiration from biological systems, where the building envelope functions like a thermally responsive \"skin\" that can autonomously adjust its optical and thermal properties in response to environmental temperature changes. Among the many approaches developed for smart building envelopes, passive thermoresponsive spectral modulation systems have attracted growing interest due to their structural simplicity and low energy demand. By dynamically tuning solar radiation transmission and thermal emission across different spectral ranges, these systems reduce the reliance of buildings on mechanical heating, cooling, and lighting, thereby enhancing overall energy efficiency and climate responsiveness. This review offers a comprehensive and unified perspective on thermoresponsive building envelope technologies, bridging transparent and opaque components-including thermochromic smart windows and tunable radiative wall coatings-within the architectural context. It places particular emphasis on multiband spectral control, material-structure integration, and performance under diverse environmental conditions.
