After printing, the sensor surface was electrochemically activated in 1.0 mol L<sup>−1</sup> NaOH by applying a constant potential of +1.2 V for 30 min.

The specimens were subsequently analyzed by voltammetry of immobilized microparticles (VIMP), in which a small amount of the pigment-binder material was mechanically transferred to the electrode surface. The electrochemical response was markedly influenced by the nature of the binder, revealing distinct behaviors among the pigment-binder systems and underscoring the role of the organic matrix in modulating copper electroactivity.

However, silicon anodes undergo significant volume changes during the lithium-intercalation and deintercalation processes, leading to interface degradation and structural failure. This is due to severe electro-mechanical coupling stresses generated during these processes. To address this critical issue, this work has developed a multi-physics (electrochemical-thermal-mechanical) coupling model for silicon-based all-solid-state batteries based on single-ion conducting electrolyte (SCE) theory. Based on this model, a low-frequency pulse charging strategy was introduced to investigate the effects of temperature and mechanical constraints on battery performance. The results indicate that temperature is a key factor determining lithium-ion distribution and stress evolution: at temperatures below 268 K, lithium-ion concentration polarization and stress accumulation increase; in the temperature range of 298–313 K, the battery achieves an optimal balance between electrochemical performance and mechanical stability; and at temperatures above 313 K, performance declines but remains superior to that under low-temperature conditions. Mechanical constraints exert an asymmetric regulation on electrode stress: external loads (0-100 MPa) reduce cathode stress but increase anode stress, and their effects on lithium-ion concentration and temperature are negligible.

The membrane was fabricated using the phase inversion technique and subsequently surface-modified with ZnO nanoparticles to enhance its chemical stability and filtration performance.

The ZnO modification improves surface hydrophilicity and surface wettability, leading to enhanced filtration efficiency by reducing pore blockage and promoting more uniform surface transport behavior. Thermal tests (TGA/DTA) show the membrane stands up better to heat and resists breaking down. When it comes to removing heavy metal ions, the membrane works remarkably well across the tested range, as long as conditions are suitable. Additionally, ZnO brings strong antibacterial properties, which helps the membrane fight off fouling and keeps it running longer.
