AI Customer ServiceThese articles explain the background of Lithium-ion battery systems, key issues concerning the types of failure, and some guidance on how to identify the cause(s) of the failures. Failure can occur for a number of external reasons including physical damage and exposure to external heat, which can lead to thermal runaway.
The onset of the failure of batteries is understood here as the fracture of the aluminum foil, which triggers the global crack formation. The global geometry of the pouch cell is defined by the radius of the cylindrical indenter and the thickness of the cell . The hardening curve of the aluminum foil is approximated by the power law .
Performance degradation is common to all battery technologies. Failure and gradual performance degradation (aging) are the result of complex interrelated phenomena that depend on battery chemistry, design, environment (temperature), and actual operation conditions (discharge rate, charge protocol, depth of discharge, etc.).
Deformation and failure of Li-ion batteries can be accurately described by a detailed FE model. The DPC plasticity model well characterizes the granular coatings of the anode and the cathode. Fracture of Li-ion batteries is preceded by strain localization, as indicated by simulation.
This capacity fade phenomenon is the result of various degradation mechanisms within the battery, such as chemical side reactions or loss of conductivity , . On the other hand, lithium-ion batteries also experience catastrophic failures that can occur suddenly.
Figure 2 outlines the range of causes of degradation in a LIB, which include physical, chemical, mechanical and electrochemical failure modes. The common unifier is the continual loss of lithium (the charge currency of a LIB). 3 The amount of energy stored by the battery in a given weight or volume.
