Lithium-ion batteries (LIBs) provide many benefits, but trace electrolyte leakage can cause serious safety risks such as thermal runaway. Although gas sensors offer a potential solution, the complexity of solvents in LIBs makes it challenging to develop sensing materials capable universally detecting multiple solvent molecules. Here, Ag@Ag2O-functionalized SnO2 nanoflowers were synthesized using self-template pyrolysis strategy for sensitive detection both common molecules and widely used electrolytes. These sensors, enhanced by abundant oxygen vacancies introduced Ag@Ag2O functionalization, exhibit excellent sensitivity, particularly dimethyl carbonate, with response 106-100 ppm, low limit 11.76 ppb, rapid response/recovery times (28/55 s) at an operating temperature 200 °C. The sensor performance was validated density functional theory calculations, which corroborated effectiveness material. In simulated LIB scenarios, puncture injection, demonstrated quick responses various compositions, indicating their practical applications. This study highlights effective method fabricating composite emphasizes significance our universal approach monitoring energy storage devices.

Timely and accurate detection of H2S is crucial for preventing serious health issues in both humans livestock upon exposure. However, metal-oxide-based sensors often suffer from mediocre sensitivity, poor selectivity, or long response/recovery time. Here, an atomic Ru species-driven SnO2-based sensor fabricated to realize highly sensitive selective at the parts per billion level as low 100 ppb. The shows a high sensing response (Rair/Rgas = 310.1) ultrafast time (less than 1 s) 20 ppm operating temperature 160 °C. Operando SR-FTIR spectroscopic characterizations DFT calculations prove that superior properties can be mainly attributed driven effect species on formation surface-adsorbed oxygen surface SnO2, which provides more active sites enhances performance SnO2 H2S. Furthermore, lab-made wireless portable monitoring system developed rapidly detect early warning, suggesting potential application system. This work novel approach fabricating gas by metal loaded metal-oxide semiconductors.
