The liquid cooling system for lithium iron phosphate battery modules usually faces the threat of coolant leakage, which would dramatically affect heat transfer performance, safety, and efficiency energy storage system. Herein, electrochemical sensing technology has been first employed to detect leakage. Specifically, ethanol is selected as additive reagent used main tested substance, sensors indirectly identify leakage by detecting leaked ethanol. In order overcome disadvantages pure SnO2 detection, including poor response, low gas selectivity, high operating temperature, microspherical-structured SnO2/In2O3/C composite designed synthesized using a tin-indium metal-organic framework (SnIn-MOF) precursor. fabricated sensor exhibits excellent gas-sensing performance. response could reach 30.1 at 280 °C, 1 mL with only 0.01% be detected sensor. Moreover, also satisfactory cycling repeatability stability. This outstanding performance attributed structural stability synergistic effects SnO2, In2O3, carbon. work innovatively proposed feasible method high-quality material detection in an system, great importance application potential field conversion.
