ABSTRACT Aqueous zinc‐iodine batteries are promising candidates for safe and low‐cost energy storage but suffer from severe degradation under low‐temperature and high‐rate conditions due to electrolyte freezing, iodine dissolution, sluggish ion transport, and interfacial instability. Herein, we report a multiscale confinement electrolyte by introducing high‐concentration Ca(ClO 4 ) 2 and a small …

ABSTRACT The conventional metal‐metal oxide configuration as a catalyst support is often considered to excite hydrogen spillover. However, it is difficult to precisely regulate hydrogen spillover. Herein, a metal‐metal oxide‐doped carbon configuration, Ru@ZrO 2 /FC, featuring a ZrO 2 ‐anchored Ru cluster over F‐doped carbon, is proposed to more easily trigger hydrogen spillover. The F‐doped carbo…

ABSTRACT Water‐electricity cogeneration systems based on photothermal and evaporative interfaces offer a promising approach to green power generation and freshwater production. System efficiency depends not only on photothermal conversion and evaporation performance but also on the often‐overlooked matching between these processes. Here, we present a dual‐bionic water‐electricity cogeneration sys…

ABSTRACT The electrochemical behavior of graphite anodes is strongly affected by structural disorder, yet graphite crystallinity is often described using averaged descriptors that do not resolve the underlying defect landscape.

ABSTRACT Ag 2 Se‐based thermoelectric thin films are attractive for near‐room‐temperature energy harvesting, yet suffer from severe non‐stoichiometry (Ag/Se > 2:1) due to Se vacancies, which induce excessive carrier concentration and degrade thermoelectric performance.
