AI Customer ServiceIn the safety evaluation of lithium-ion batteries, the nail penetration test simulating the possible internal short-circuit for batteries and the United Nations (UN) recommendation test for the safety confirmation test at transportation*2) are applicable.
The nail penetration testing machine as shown in Figure 2 was devised in order to apply to a large-scale cell*3). By setting the lithium-ion battery into the nail penetration test container and substituting inside the container with inert gas, it is possible to perform the test without generating ignition by generated gas.
In any test and at storage after tests, the battery voltage, temperature on the battery surface, etc. are monitored and evaluation is performed by confirming the presence or absence of abnormality such as burst, ignition and liquid leakage.
A great introductory presentation by Billy Wu, Dyson School of Engineering, Imperial College. It is notoriously difficult to get repeatable results with the nail penetration test. The nail penetration test is one method of triggering thermal runaway in a cell. Thermal runaway propagation within cells is generally highest for nail penetration .
Charge the battery with the current of twice the maximum continuous charging current recommended by the maker. The minimum voltage of the test is specified by the recommended charging voltage. • There shall be no burst, ignition within 7 days after the test.
The targeted batteries are all lithium batteries, the electric cell and assembled batteries of the lithium-ion batteries. Regarding the test method, it is specified to execute eight items of the test, from T1 to T8.
