Problems like thermal runaway and short circuits between the positive (cathode) and negative (anode) poles of the battery can result [1,2]. Therefore, it is important to have solutions for efficient at-line inspection during battery production for the detection and analysis of burrs.
In 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.
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.
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.
X-ray inspection for cylindrical lithium-ion batteries X-ray inspection for prismatic/pouch lithium-ion batteries (winding type) X-ray inspection for prismatic/pouch lithium-ion batteries (stacking type) As the causes of LiB failures gradually become clearer, there is a growing demand to inspect more complex structures and find minute defects.
