Synergetic effect of temperature and humidity on the leakage of KOH electrolyte and related reliability of zinc-air batteries

The Zinc-air primary batteries (ZAB’s) are prone to electrolyte leakage upon exposure high temperature and humidity conditions. Potassium hydroxide is a hygroscopic corrosive compound it can cause various electrochemical corrosion failures for the attached electronics inside device. In this study, effect of humid conditions on from three different Zinc Air Battery variants were investigated. exposed hot conditions, qualitative Gel test with pH indicator was used visually observe individual set battery variants. residues released identified by FTIR quantified using titration method. SEM-EDS analysis also performed examine surface sealants eventual damage. related reliability voltage discharge test. hygroscopicity properties pure studied water sorption/desorption equipment correlated electro impedance spectroscopy an interdigitated board. results study indicate that increase in caused increased amount under saturated Leakage damage sealant gasket, clogged oxygen ventilation holes batteries, exhibits when
