Abstract
Li1+xMn2−xO4 samples show reversible oxygen intercalation and deintercalation upon heating in the temperature range between 700 and 950 °C which can be monitored using thermal gravimetric analysis. There are two kinks, due to phase transitions, in the weight‐temperature curve observed on heating. The temperature of the low‐temperature kink depends linearly on x and therefore can be used to infer the sample stoichiometry. This provides a simple and straightforward quality control check on Li1+xMn2−xO4 samples for the lithium battery industry.Keywords
