Metal–organic frameworks (MOFs) are promising protective interlayers to mitigate Zn dendrite growth and parasitic side reactions, yet their aqueous vulnerability and unresolved electronic mechanisms hamper practical application. Herein, we propose an electronic structure engineering strategy via d‐p orbital hybridization to customize the Zn anode interphase. Using UiO‐66 derivatives (‐NH ₂ , ‐COOH, and ‐F ₄ ) as models, theoretical calculations reveal that strengthening the substituents’ electron‐withdrawing capability deepens d‐p orbital coupling and shifts the π* d‐band center toward the Fermi level, thus inducing intense spatial charge polarization and enhancing Zn ²⁺ affinity. Experimentally, the highly fluorinated UiO‐66‐F ₄ achieves the highest Zn ²⁺ adsorption, drives selective SO ₄ ²⁻ exclusion, accelerates desolvation, and enables rapid ion transport. Synergizing with inherent physical hydrophobicity, this unique electronic‐physical dual‐shield of the UiO‐66‐F ₄ interlayer effectively averts H ₂ O‐induced side reactions and ensures highly reversible Zn plating/stripping. Consequently, the Zn@UiO‐66‐F ₄ anode delivers a 3600 h lifespan at 5 mA cm ⁻² and sustains 560 h under a stringent 90% depth of discharge, outperforming most MOF‐modified anodes. Furthermore, flexible full cells exhibit impressive cycling stability and reliably power wearable systems even under severe deformation. Overall, this work establishes d‐p orbital hybridization regulation as a powerful paradigm for customizing advanced functional interlayers toward ultra‐stable Zn metal anodes.

Graphene-confined topological conversion yields robust C@MoSe ₂ @G architectures for rapid and reliable K/Na-ion storage.

The sluggish kinetics, severe structural degradation, and ambiguous reaction pathways of conversion‐type anodes remain formidable bottlenecks for potassium‐ion batteries. Herein, a neuron‐inspired orbital‐interface engineering strategy is proposed to construct a hierarchical Co‐FeS ₂ /C@C composite via a novel in situ FeS ₂ ‐to‐MOF reconstruction, where porous Co‐FeS ₂ nanoparticles are intertwined with an internal carbon network and encapsulated within a robust carbon shell. Functionally, synergistic orbital (co‐doping) and interface (carbon network) engineering are rationally tailored to boost the intrinsic conductivity and promote ion diffusion of FeS ₂ , while the hierarchical porosity and outer shell buffer volume fluctuations, thereby concurrently enhancing reaction kinetics and structural stability. To validate this, in situ XRD first demonstrates the highly reversible successive conversion mechanism of FeS ₂ . Furthermore, comprehensive experimental and theoretical results verify optimized electronic states, lowered K ⁺ migration barriers, and robust structural integrity. Consequently, the Co‐FeS ₂ /C@C anode delivers an exceptional rate capability (268 mA h g ⁻¹ at 20 A g ⁻¹ ) alongside long‐term cycling durability, outperforming most reported metal sulfide‐based anodes. Moreover, as‐assembled full cells exhibit outstanding battery performance even under severe mechanical deformation, reliably powering diverse high‐demand electronics and wearable sensor systems. Ultimately, this biomimetic paradigm offers a compelling strategy to develop high‐power and durable electrodes for next‐generation energy storage systems.

The rapid growth of flexible Internet of Things devices and multisensory human-computer interaction necessitates advanced systems capable of multimodal data sensing, processing, and feedback in an intelligent and energy-efficient manner. However, conventional architectures face limitations in energy inefficiency and interface mismatch due to the fragmented architecture of sensing, processing, and feedback units. Inspired by biological sensory systems, we introduce an MXene-based flexible dual-mode sensing-processing-visualizing integrated system into a single wearable device through a hierarchical MXene platform combining piezoelectric nanogenerators (mechanosensation), optoelectronic synapses (visual processing), and color-shifting quantum dot light-emitting diodes (optical feedback) with optimized interfaces. The wearable integrated system demonstrates tactile-visual signal recognition capabilities, biological self-protection behavior to adapt to environmental stimuli, dynamic trajectory recognition, and spatial positioning for motion recognition, which are highly desired in multisensory interaction. The bio-inspired material-architecture-function co-design strategy and integrated system promote the development of wearable neuromorphic hardware, edge computing, and intelligent human-machine interaction.

Polyaniline (PANI) as a flexible matrix has been widely used in sensor applications, while the usage of pure PANI is hampered due to its insufficient electrical conductivity and limited surface area. Herein, a high-performance flexible humidity/pressure sensor has been developed based on a three-dimensional (3D) PANI-coated melamine sponge (MS) synthesized through protonic acid doping and dip coating methods, featuring breathable and environmentally benign properties. In this hybrid, the adhesion of PANI on the 3D MS matrix can enhance the active surface of PANI for superior pressure and humidity sensitivity, outperforming the single functionality and performance of a two-dimensional (2D) PANI film. Thus, this 3D MS@PANI sensor exhibits a superior sensitivity of 0.24 kPa⁻¹ within a pressure range of 5–14 kPa and maintains excellent cycling stability over 10 000 cycles with response and recovery times of 370 ms and 380 ms, respectively. As a humidity sensor, it shows high response sensitivities of 1.02 and 0.79 μA per %RH in dry air and N₂ environments, respectively, demonstrating good recognition ability and stability. Moreover, the as-prepared 3D MS@PANI sensor can be applied for real-time human motion monitoring. This PANI-based sensor, developed by transitioning from 2D flat films to 3D breathable sponges, provides a cost-effective and simple processing solution for the development of flexible electronic devices.

Through comprehensive theoretical computations and experimental analyses, ME-SSe nanoparticles in the dual carbon framework are obtained via a medium-entropy cation and alloy anion co-tuning strategy, exhibiting enhanced potassium-ion storage.

Organic–inorganic hybrid halide perovskites have recently gained significant attention due to their outstanding optoelectronic properties. However, the application of halide perovskites in lithium-ion batteries (LIBs) is still in its infancy with inferior battery performance and an unclear reaction mechanism. This study presents a layered perovskite Li₂(C₂H₇NO₃S)₂CuCl₄ (LTCC) and deciphers the role of van der Waals heterostructures in high-performance anode materials for LIBs. The LTCC anode can achieve a remarkable specific capacity of 861 mA h g⁻¹ at 0.1 A g⁻¹ after 100 cycles. Moreover, it retains a high discharge capacity of 548 mA h g⁻¹ over 550 cycles at 1.0 A g⁻¹, exhibiting outstanding cycling stability among perovskite-type anode materials for LIBs. Comprehensive characterization studies illustrate the partially reversible conversion reaction of the LTCC anode to form CuCl, LiCl, and Li taurine during the lithiation process. Furthermore, experimental and theoretical results reveal that the unique van der Waals heterostructure of LTCC can enhance the structural stability and boost the Li-ion adsorption/transportation ability, thus accounting for the superior lithium storage performance. This study not only sheds light on the accurate electrochemical reaction mechanism of perovskite-type materials but also provides valuable insights for developing high-performance perovskite-based anodes for LIBs.
