How can mechanical tests be used to evaluate battery failure risk?

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 , .

Why is mechanical characterization of Li-ion batteries important?

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.

What are the bending specifications for battery cells?

Following the ASTM standards, we performed four-point bending simulations on battery cells to determine the testing specifications. The distance between the two static noses D S is 180 mm (24 times of cell thickness), and four different distances between the two loading noses D L are compared.

Why do we need a harmonised testing protocol for automotive batteries?

Taking into consideration the importance of this issue, it is advisable that future standardisation/regulation developments consider a harmonized testing guidance and protocols to ensure that chemical hazards of automotive batteries are appropriately assessed in order to ensure the safety of vehicle occupants and surrounding persons.

What is the mechanical behavior of a battery cell?

As we concluded in a previous publication , the mechanical behavior of a battery cell is largely governed by the graphite coating layers instead of the current collectors, cathode coating, or separator. The graphite coating is porous and less anisotropic in mechanical responses than the overall layered structure.

What are the potential loads on vehicular lithium-ion power batteries?

According to road conditions and traffic accident data, we categorize the potential loads on vehicular lithium-ion power batteries into three main types: vibration, mechanical shock, and crash. Fig. 1 summarizes the typical failure behaviors resulting from these three categories of mechanical loads. Fig. 1.
