Regulating Polymer Demixing Dynamics to Construct a Low‐Tortuosity Host for Stable High‐Energy‐Density Lithium Metal Batteries

open access: yesAdvanced Materials, EarlyView.
Tortuosity‐controlled hosts, fabricated via regulated polymer demixing, create vertically aligned, low‐tortuosity (LT) frameworks with lithiophilicity gradients. The LT host enhances Li‐ion transport kinetics, promotes homogeneous bottom–up Li deposition. When paired with LiNi0.8Co0.1Mn0.1O2 cathodes, a double‐stacked pouch‐type full cell achieves high

Oriented Crystallization of Perovskite Film via Fluorine‐Containing Hyperbranched Polymer for Efficient and Stable Perovskite Solar Cells

open access: yesAdvanced Materials, EarlyView.
A fluorine‐containing hyperbranched polymer is developed to guide oriented crystallization and construct a cross‐linked hydrophobic network, enabling the formation of high‐quality perovskite films with enhanced environmental stability. The resulting devices deliver a PCE of 26.05% (0.04 cm2) and 22.43% (16.1 cm2), while maintaining 97% of their initial

Linear and Symmetric Artificial Synapses Driven by Hydrogen Bonding for Accurate and Reliable Neuromorphic Computing

open access: yesAdvanced Materials, EarlyView.
Hydrogen‐bond‐driven interface engineering enables highly linear and symmetric artificial synapses based on CsPbI3–PVA hybrids. This strategy suppresses trap states and guides directional ion migration, yielding stable optoelectronic plasticity. The devices achieve ultralow power operation and human‐like learning in neuromorphic networks, offering a ...
