Abstract: Soft internal short circuit (ISCr) in lithium-ion batteries is a latent risk, and it is a primary reason for thermal runaway with blaze and explosion. Early detection of ISCr is necessary to ensure safe utilization of the batteries.
External short circuit (ESC) faults pose severe safety risks to lithium-ion battery applications. The ESC process presents electric thermal coupling characteristics and becomes more complex when the batteries operate in large group, which often lead to serious consequences.
Micro-short circuit (MSC) of a lithium-ion battery cell is a potential safety hazard for battery packs. How to identify the cell with MSC in the latent phase before a thermal runaway becomes a difficult problem to solve. We propose a diagnosis method to detect the MSC according to the remaining charging capacity (RCC) variations between cells.
The increase of short circuit severity is often accompanied by the increase of the battery self-discharge rate and calorific value, leading to fire, and even thermal runaway and other serious problems .
Among all the known types of battery failure modes, the internal short circuit (ISC) tops the list of the major safety concerns for the lithium-ion battery. However, a clear picture of the LIB's electrochemical safety behavior in the context of the ISC remains to be fully established.
