Abstract
The development of highly sensitive electrolyte leakage monitoring sensors is critical for enabling early fault detection and ensuring the safe operation of lithium-ion battery (LIBs) systems. In this study, perovskite LaFeO3 hollow microspheres with an average diameter of 850 nm were synthesized via a hydrothermal method. Gas-sensing tests demonstrated that the LaFeO3 hollow microsphere sensor exhibited exceptional responsiveness to dimethyl carbonate (DMC) gas, achieving a remarkable response value of 67.9 toward 10 ppm DMC at an operating temperature of 150 °C. The sensor also showed a fast response/recovery rate (170/90 s), excellent selectivity, long-term stability, and a low detection limit of 20 ppb. This excellent gas-sensing performance may be attributed to the high specific surface area and well-developed mesoporous structure of the hollow structure. Moreover, it demonstrated rapid response capabilities in simulated leakage detection scenarios. This work presents a novel perovskite LaFeO3-based sensor that can effectively detect DMC gas leakage and provide an effective strategy for enhancing safety monitoring in LIB applications.
期刊介绍:
ACS Sensors is a peer-reviewed research journal that focuses on the dissemination of new and original knowledge in the field of sensor science, particularly those that selectively sense chemical or biological species or processes. The journal covers a broad range of topics, including but not limited to biosensors, chemical sensors, gas sensors, intracellular sensors, single molecule sensors, cell chips, and microfluidic devices. It aims to publish articles that address conceptual advances in sensing technology applicable to various types of analytes or application papers that report on the use of existing sensing concepts in new ways or for new analytes.
