| titleOfInvention | Semi-quantitative detection method for lithium content in primary mixed material sample of ternary cathode material |
| abstract | The invention discloses a semi-quantitative detection method for lithium content in a primary mixed material sample of a ternary cathode material, which comprises the following steps: calculating sample weighing according to the theoretical lithium content of a given primary mixing sample in the production process, and weighing the primary mixing sample to a first container; according to the upper limit and the lower limit of the lithium content specification tolerance given in the production process, the proportion of the lithium raw material and the precursor in the upper limit sample and the lower limit sample is calculated, and the upper limit sample and the lower limit sample are respectively weighed to a second container and a third container; respectively adding water into the first container, the second container and the third container, stirring uniformly, then respectively adding acid, and stirring for reaction; and respectively testing the pH value of the solution, and judging the sample to be unqualified when the pH value of the sample is close to or exceeds the pH values of the upper limit sample and the lower limit sample. The method has the advantages of simple operation, low cost, less time consumption, high detection efficiency, small influence of external conditions such as temperature, humidity and the like, and capability of quickly judging whether the sample is qualified. |
