With the large number of lithium-ion batteries in use and the applications growing, a functional rapid-testing method is becoming a necessity. Several attempts have been tried, including measuring internal resistance, and the results have been mixed.
Li-ion shares similarities with lead acid; the Spectro™ technology that is used to measure the capacity of lead acid batteries will also be able to service Li-ion (See BU-904: How to Measure Capacity) No rapid-test can evaluate all battery symptoms and there are always outliers that defy the test protocol. Correct prediction should be 9 out of 10.
Inside the climate chamber, the cells were connected to a battery test system (PAT-Tester-x-8 from EL-Cell GmbH, Hamburg, Germany) which is depicted in Figure 1 . The battery test system allows both the real-time measurement and control of the cell and electrode voltages.
Therefore, mechanical tests can be used to evaluate the failure risk of the battery cells. A well-known example is the nail penetration test which is widely applied for the study of thermal runaways. The cell structure can be easily fractured by the sharp rigid tip, causing direct contacts among layers, and causing short circuits , .
In a narrow range of stress state, various models have nearly identical performance. Mechanical characterization of Li-ion battery cells is becoming increasingly important as the community becomes more aware that the underlying mechanisms of battery failure and degradation involve the complex interplay between electrochemistry and mechanics.
