However, conventional components such as multi-layer ceramic capacitors (MLCCs) fall short in energy density and long-term power delivery. Here, we introduce solid-state-based multi-layer composite batteries (MLCBs) that achieve high energy/power densities and full SMT integration. To address the limitations of existing energy storage systems, key material and structural innovations were integrated into all components of the MLCB. Specifically, a polymer-based mixed ionic–electronic conducting (MIEC) coating was applied to NCM and LTO active materials, enabling high-loading electrodes with enhanced interfacial stability. In parallel, we developed a PVDF-HFP-based hybrid polymer electrolyte reinforced with ceramic fillers and a LiOH·H<sub>2</sub>O additive. This combination promoted the formation of a stable pre-SEI via a controlled Li<sup>+</sup> coordination environment. Based on these design strategies, the resulting prototype MLCB with 10-unit cells demonstrates an areal energy density of 34.6 mWh cm<sup>−2</sup> and a power density of 89.3 mW cm<sup>−2</sup>, with excellent cycling retention (89.5% over 200 cycles, at 0.2C-rate).

This article provides a perspective on the opportunities and challenges associated with novel materials for optical waveguide sensing. Emerging classes include polymers and hydrogels, two-dimensional materials, nanostructured coatings, metamaterials, and hybrid porous frameworks offer pathways to enhance light-matter interaction, improve selectivity, enable flexible and wearable formats, and support multifunctional integration with microfluidics and electronics.

By critically examining both the promise and the practical challenges of these material platforms, this work outlines a roadmap for the next decade of research.

However, a fundamental issue in these stretchable composites has long been overlooked: the crack-initiation resistance is much lower than that of soft tissues. The crack can easily initiate and grow in the matrix of stretchable composites. This low crack-initiation resistance severely damages the integrity and function of stretchable composites. Here, we demonstrate a design principle to develop stretchable materials with high crack-initiation resistance. To illustrate the principle, we develop a stretchable composite of a knitted fabric and a highly entangled matrix. The matrix is tough to prevent damage caused by the large movement of fibers. The interface is strengthened to prevent fiber pullout from the matrix. Synergistically, the initiation toughness of this stretchable material is improved to 46.9 kJ/m<sup>2</sup>, much higher than that of bovine pericardium. The principle of stretchable material for achieving high crack-initiation resistance may aid the applications in artificial tissues, soft robotics, and flexible electronics.</div></div>","PeriodicalId":387,"journal":{"name":"Materials Today","volume":"93 ","pages":"Article 103199"},"PeriodicalIF":22.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147400729","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}
