| Abstract Scope |
This study presents the development of a new sensor based on gold nanoparticles for detecting lithium in battery leakages. For the aim of developing the gold nanoparticle sensor, an experimental plan involving two factors, pH and gold concentration, was developed for the gold solution optimization. After that, the gold sensor was deposited on the sensor surface through electroplating to achieve a dendritic shape. Finally, the sensor's ability to detect lithium hexafluorophosphate was investigated using both cyclic voltammetry and impedance spectroscopy techniques using various electrolytes commonly used in the batteries industry. Results showed that the sensor successfully detected lithium in acetonitrile across a range of concentrations using cyclovoltammetry analysis, while impedance spectroscopy results indicated detection capabilities in methyl acetate up to a concentration of 10-6M. However, further research is needed to explore the sensor's potential for detecting lithium in gaseous states. |
