Abstract The development of aqueous zinc metal batteries (AZMBs) is significantly impeded by the poor cycle stability Zn anodes due to uncontrolled dendrite growth and low Coulombic efficiency (CE). Herein, for first time, SeO 2 additives are introduced into ZnSO 4 electrolyte enhance anode. According experimental results, protective ZnSe layer initially in‐situ formed on surface prior plating, which acts as a shield inhibiting parasitic reactions formation. Moreover, this additive strategy...
Abstract Thermal transistors that electrically control heat flow have attracted growing attention as thermal management devices and phonon logic circuits. Although several are demonstrated, the use of liquid electrolytes may limit application from viewpoint reliability or leakage. Herein, a solid‐state transistor can electrochemically with an on‐to‐off ratio conductivity (κ) ≈4 without using any is demonstrated. The multilayer film composed upper electrode, strontium cobaltite (SrCoO x ),...
Transparent conductive oxides (TCOs) have attracted significant attention due to their high electrical conductivity and optical transparency, which are crucial for modern optoelectronics. Among TCOs, indium tin oxide (ITO) stands out its superior properties wide range of applications. The performance ITO is heavily influenced by the fabrication process level (SnO2) substitution. In this work, we systematically investigated electron transport behavior amorphous crystalline films as a function...
Manganese dioxide (MnO2) cathodes are widely studied for aqueous zinc-ion batteries (AZIBs) because of their high theoretical capacity and energy density. However, the formation "dead manganese" Mn2+ dissolution during cycling lead to active materials loss significant decay, impeding practical application.

Thermal transistors have the remarkable ability to electrochemically switch thermal conductivity (κ) of an active material. Several been reported control heat flow, but they are impractical because use liquid electrolytes. Recently, we realized a solid-state transistor that controls κ SrCoOx (2 ≤ x 3) using 0.5-mm-thick yttria-stabilized zirconia (YSZ) single crystal substrates as solid electrolyte at 280 °C. The applicable electric current is low (50 μA) due high electrical resistivity YSZ...

Abstract Potassium (K) metal anodes suffer the main obstacle of uncontrollable dendrite growth. One best ways to overcome this challenge is build a stable potassiophilic host. Herein, we designed Metal‐Organic Frameworks (MOF)‐derived CuO nanoparticles on carbon fiber cloth (CC) as high host prestore molten potassium for dendrite‐free K anode. The three‐dimensional has relatively large surface area and excellent mechanical strength, which helps lower local current density well buffer volume...
