These 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.
Fault mechanisms LIBs suffer from potential safety issues in practice inherent to their energy-dense chemistry and flammable materials. From the perspective of electrical faults, fault modes can be divided into battery faults and sensor faults. 4.1. Battery faults
Negative/positive (N/P) ratio failure defects. In lithium-ion batteries, the areal capacity of the anode is designed to be higher than that of the cathode, maintaining an N/P ratio greater than 1. However, uneven coating of the anode can result in localized areas where the N/P ratio is less than 1 or even 0 due to anode material loss.
In short, it is evident that the arc is a novel risk factor in the thermal failure of LIBs. Moreover, the arc method, which combines electrical and thermal properties, exacerbates the issues of thermal failure and fire propagation in batteries. 3.5. Feasibility of detection methods for different arc stages
In Refs. [20, 21], a detailed study was conducted on arc fault problems triggered by the current interrupt device (CID) in 18650 lithium-ion batteries (LIBs). These studies indicate that at the moment the CID disconnects, even a voltage as low as 19 V can initiate an arc, while 35 V can sustain it.
Due to severe internal failure of the battery, the circuit is disrupted. Consequently, the arc extinguishes due to a lack of energy input, as shown in Stage V of Fig. 2. Therefore, according to the experimental observations, the pulling arc method triggered severe disaster phenomena in LIBs with SOC levels of 30 %, 60 %, and 100 %.
