Recently, nonmetal NH4+ ions have attracted extensive attention for use as charge carries in the field of energy storage due to their abundant resources, environmental friendliness, and low cost. However, the development of aqueous ammonium‐ion batteries (AAIBs) is constrained by the absence of high‐voltage and long‐life materials. Herein, different tunnel‐structure MnO2 materials (α‐, β‐, and γ‐MnO...
A flexible sensor that simultaneously senses temperature and pressure is crucial in various fields, such as human‐machine interaction, artificial intelligence, and biomedical applications. Previous research has mainly focused on single‐function flexible sensors for e‐skins or smart devices, and integrated bimodal sensing of temperature and pressure without complex crosstalk decoupling algorithms remains...
Rechargeable aluminum batteries (RABs) are an emerging energy storage device owing to the vast Al resources, low cost, and high safety.

The pursuit of enhancing the heat transfer performance of composite elastomers as the thermal interface materials (TIMs) is a compelling and timely endeavor, given the formidable challenges posed by interfacial thermal transport in the domains of energy science, electronic technology, etc. Despite the efficacy of phase change materials (PCMs) in enhancing composite elastomers’ interfacial compatibility,...
Nanofiber is the critical building block for many biological systems to perform various functions. Artificial assembly of molecules into nanofibers in a controllable and reversible manner will create “smart” functions to mimic those of their natural analogues and fabricate new functional materials, but remains an open challenge especially for nature macromolecules. Herein, the controllable and reversible...
Preparing MoS2‐based materials with reasonable structure and catalytic activity to enhance the sluggish kinetics of lithium polysulfides (LiPSs) conversion is of great significance for Li–S batteries (LSBs) but still remain a challenge.
