What is the evolution mechanism of foreign matter defect in lithium-ion cells?

Evolution mechanism of foreign matter defect in the lithium-ion cell is revealed. Sudden spontaneous combustion of lithium-ion cells under non-abuse is reproduced. Self-induced internal-short-circuit fusing of lithium-ion cells is reproduced. Early warning strategy for sudden spontaneous combustion of batteries is proposed.

How to detect internal defects in lithium-ion batteries?

Detection of internal defects in lithium-ion batteries using lock-in thermography Blister defect detection based on convolutional neural network for polymer lithium-ion battery Process-product interdependencies in lamination of electrodes and separators for lithium-ion batteries

How to avoid the generation of batteries containing foreign matter?

In order to avoid the generation of batteries containing foreign matter as much as possible, battery manufacturers need to establish a complete and strict raw material detection mechanism, workshop cleaning mechanism, insulation withstand voltage (Hi-pot) test mechanism, and self-discharge test mechanism.

What is the evolution mechanism of foreign matter defect in a battery?

Through intentionally making defect batteries, aging experiments, and characterization analysis at different stages, the evolution mechanism of foreign matter defect in the battery is revealed. The self-induced internal-short-circuit fusing and sudden spontaneous combustion of the battery under non-abuse are all reproduced.

Does foreign matter cause battery damage?

The battery damage situation caused by the foreign matter of different particle sizes during the battery production process is revealed. Through the non-abuse aging cycle test, we reproduced the SSC and the self-induced ISC fusing of lithium-ion cells. Then through the analysis of the test data, we propose the early warning method for SSC.
