Sodium (Na)-ion batteries offer an attractive option for low cost grid scale storage due to the abundance of Na. Tin (Sn) is touted as a high capacity anode Na-ion with theoretical 847 mAh/g, but it has several limitations such large volume expansion cycling, slow kinetics, and unstable solid electrolyte interphase (SEI) formation. In this article, we demonstrate that consisting Sn thin film deposited on hierarchical wood fiber substrate simultaneously addresses all challenges associated...
Significance A long-standing challenge in material design is to overcome the conflict between strength and toughness, because they are generally mutually exclusive. To address this challenge, we rationally cellulose-based nanopaper investigate dependence of their mechanical properties on constituent cellulose fiber size. Surprisingly, find that both toughness increase simultaneously (40 130 times, respectively) as average diameter fibers decreases from 27 μm 11 nm, suggesting promising...
Abstract Soft ionic conductors, such as hydrogels and ionogels, have enabled stretchable transparent ionotronics, but they suffer from key limitations inherent to the liquid components, which may leak evaporate. Here, novel liquid‐free conductive elastomers (ICE) that are copolymer networks hosting lithium cations associated anions via bonds hydrogen demonstrated, intrinsically immune leakage evaporation. The ICEs show extraordinary mechanical versatility including excellent stretchability,...
As one of the most promising drug delivery carriers, hydrogels have received considerable attention in recent years. Many previous efforts focused on diffusion-controlled release, which allows to load and release drugs vitro and/or vivo. However, it hardly applies lipophilic due their poor compatibility with hydrogels. Herein, we propose a novel method for based dual pH-responsive hydrogel actuator. Specifically, is encapsulated can be released by pH-controlled capsule switch. Inspired...
Hydrogen bond engineering is widely exploited to impart stretchability, toughness, and self-healing capability hydrogels. However, the enhancement effect of conventional hydrogen bonds severely limited by their weak interaction strength. In nature, some organisms tolerate extreme conditions due strong interactions induced trehalose. Here, we report a trehalose network-repairing strategy achieved covalent-like bonding improve hydrogels' mechanical properties while simultaneously enabling them...
Abstract Biological materials with hierarchical architectures (e.g., a macroscopic hollow structure and microscopic cellular structure) offer unique inspiration for designing manufacturing advanced biomimetic outstanding mechanical performance low density. Most conventional only benefit from bioinspired architecture at single length scale material structure), which largely limits the of resulting materials. There exists great potential to maxime by leveraging structure. An ink‐based...
Abstract Stretchable ionic conductors such as hydrogels and ionic‐liquid‐based gels (aka ionogels) have garnered great attention they enable the development of soft ionotronics. Notably, ionotronic devices inevitably operate in humid environments or under mechanical loads. However, many previously reported ionogels, however, are unstable with varying humidity levels owing to hydrophilicity, their liquid components (i.e., liquid, water) may leak easily from polymer matrices loads, causing...
Abstract Artificial intelligence robots predicted in sci‐fi movies have attracted increasing attention recent years, and much effort has been devoted to improving the sensing manipulation performance of robots. The development robotic skins capable handling complex external pressure environments is highly desired for intelligent However, this remains a major challenge due lack materials that can combine extremely low detection limits wide ranges. Inspired by synergistic strategy dual...
Abstract Fractocohesive length, defined as the ratio of fracture toughness to work fracture, measures sensitivity materials in presence flaws. The larger fractocohesive more flaw‐tolerant and crack‐resistant hydrogel. For synthetic soft materials, length is short, often on scale 1 mm. Here, highly flaw‐insensitive (HFI) single‐network hydrogels containing an entangled inhomogeneous polymer network widely distributed chain lengths are designed. HFI demonstrate a centimeter‐scale 2.21 cm,...
Atomic-layer-deposition (ALD) coatings have been increasingly used to improve battery performance. However, the electrochemical and mechanistic roles remain largely unclear, especially for ALD on electrodes that undergo significant volume changes (up 100%) during charging/discharging. Here we investigate an anode consisting of tin nanoparticles (SnNPs) with ALD-Al2O3 coating. For first time, in situ transmission electron microscopy unveiled dynamic mechanical protection coating by coherently...
From in situ transmission electron microscopy (TEM) observations, we present direct evidence of lithium-assisted welding between physically contacted silicon nanowires (SiNWs) induced by electrochemical lithiation and delithiation. This weld two SiNWs demonstrates facile transport lithium ions electrons across the interface. our estimate shear strength welded region after delithiation to be approximately 200 MPa, indicating that a strong bond is formed at junction SiNWs. phenomenon could...
Abstract Red phosphorus offers a high theoretical sodium capacity and has been considered as candidate anode for sodium-ion batteries. Similar to silicon anodes lithium-ion batteries, the electrochemical performance of red is plagued by large volume variation upon sodiation. Here we perform in situ transmission electron microscopy analysis synthesized red-phosphorus-impregnated carbon nanofibers with corresponding chemo-mechanical simulation, revealing that, sodiated becomes softened...

Mechanics modeling reveals critical role CNTs enhanced by increasing friction adhesion between 2D nanosheets. The 3DP GC hold distinct advantages:...
The muscle-like activities of liquid crystalline elastomers (LCEs) offer great potential for designing future soft machines. Their motion complexity, however, relies on inflexible and cumbersome mesogen alignment techniques. Here, a digital photocuring method ultrafast template-free fabrication LCE artificial muscles capable designable complex motions is reported. This utilizes the intrinsic light attenuation in through-plane direction to create reversible bending action. To turn this simple...
Interfacial instability is a fundamental issue in heterostructures ranging from biomaterials to joint replacement and electronic packaging. This challenge particularly intriguing for lithium ion battery anodes comprising silicon as the storage material, where ultrahigh capacity accompanied by vast mechanical stress that threatens delamination of current collectors at other side interface. Here, we describe Si-beaded carbon nanotube (CNT) strings whose interface controlled chemical...
One-dimensional (1-D) nanostructures such as nanowires and nanotubes have been widely explored for anodes with high specific capacity in Li-ion batteries, which effectively release the mechanical stress to avoid structure pulverization. However, 1-D typically a surface area, leads large irreversible first cycle due solid electrolyte interface (SEI) formation. Two dimensional (2-D) nanowalls can address same challenges nanostructures, much lower area. For time, we demonstrated 2-D nanowall...
This communication describes a novel strategy to achieve programmable shape transformation of hybrid hydrogel sheets by modulating both the in-plane and out-of-plane mismatches in mechanical properties.
Far-from-equilibrium (FFE) conditions give rise to many unusual phenomena in nature. In contrast, synthetic shape-shifting materials typically rely on monotonic evolution between equilibrium states, limiting inherently the richness of behaviors. Here we report an unanticipated behavior for a hydrogel that can be programmed operate FFE-like behavior. During its temperature triggered event, stress induces uneven water diffusion, which pushes off based natural pathway. The resulting geometric...
