Do we need a standardized test for thermal runaway triggering?
A standardized test for thermal runaway triggering is also introduced. The recent fire accidents in electric vehicles and energy storage power stations are discussed in relation to the upgrading of the rational test standards.
What are the key features of six needle penetrations?
List of the key features of six needle penetrations with the experimental conditions: 100% SOC and a penetration depth of 100 m. In four out of six tested cells, a TR developed from the dynamic ISC (type IIb). Here, the joule heat ( Many cell components combust in the TR, and consequently, the cell mass was reduced by 52 to 58%.
How flexible is a battery based on Young's modulus & yield strains?
Battery components made from different materials exhibit a wide variation of Young's modulus and yield strains. The level of battery flexibility is principally determined by the most fragile components, analogous to the Cannikin law. The less flexible component has to be particularly designed in battery fabrication.
How long should a test battery be discharged?
IEC 62619-2022 requires the test battery to be discharged at a discharge rate of 1 C for a test period of 90 min. In UL 1973-2022 , the test battery is discharged with the maximum discharge current for an additional 30 min after reaching the lower limit of the normal discharge voltage.
