Abstract This study presents a novel anti‐fatigue hydrogel electrolyte with slip‐ring structure for next‐generation flexible wearable energy storage systems. Conventional quasi‐solid aqueous zinc‐ion batteries (ZIBs) electrolytes often suffer from mechanical degradation under repeated stress, limiting practical use. To overcome this, dual‐Polyrotaxane (DPR)‐polyacrylic acid (PAA) unique architecture is synthesized, that enhances durability, self‐healing, and adhesion. The interwoven DPR PAA...

Abstract This study investigates the degradation of safety characteristics in commercial NaNi 1/3 Fe Mn O 2 (NFM) sodium‐ion batteries (SIBs) under mild electrical abuse, focusing on impact a single abuse event capacity, impedance characteristics, and thermal stability, reveals pattern long‐term cycles. The research finds that while has limited effect battery internal electrochemical properties still change. Mild overcharge reduces stability anode material, increased sodium plating surface...

A key challenge for unmanned aerial vehicle (UAV) spraying sometimes used in tea plantations is the downwash flow structure there stronger than crops. In addition, UAV spray affected by relationship between nozzle design and pesticide. However, little current research on this aspect. As a preliminary step study focuses most appropriate pesticide designated six-rotor according to nozzle-pesticide using three-dimensional computational fluid dynamics model. This model considers effect...

Abstract This study investigates the thermal runaway characteristics of lithium-ion batteries and sodium-ion under external heating conditions. By collecting temperature, strain, voltage data, behavior two-type is compared. Results show that experience rapid temperature rise early onset internal damage, evidenced by sharp drop increased rate. In contrast, demonstrate slower TR but exhibit more severe effects, including higher peak temperatures significant physical damage due to combustion....
