| titleOfInvention | A kind of method lithium battery diaphragm processed and simultaneously measure contained metallic element |
| abstract | With microwave dissolver, lithium ion battery separator is processed, then use ICP-AES (ICP AES) to measure Zn, Pb, Cd, Mn, Fe, Mg, Ca, Cu, Na9 kind metallic element in lithium battery diaphragm simultaneously.Result shows: in different lithium battery diaphragm, each metal element content there are differences.Ca and Na content in two kinds of lithium battery diaphragms is the highest, Mg and Fe content takes second place, Cu and Zn content is minimum, and Mn, Cd and Pb are undetected.Under optimal instrument working condition, the correlation coefficient of each element to be measured is 0.999965 0.999998, and relative standard deviation (RSD) is 0.25% 1.56%.Sample is carried out mark-on recovery test, and the response rate is between 94.3% 108.3%.Use metallic element in the method detection testing sample that microwave digestion technology and ICP AES technology combine have simple, quick, environmental pollution is little, measurement result preci-sion and accuracy advantages of higher. |
