Advancements in System Design, Integration & Testing for Safety & Reliability
"Study of Polarization Effect and Thermal Stability in Aged Lithium-Ion Battery"- By Mahmood Tabaddor, PhD, Underwriters Laboratories
Research into the safety performance of lithium-ion cells has increased tremendously in recent years.
Field failures, though rare, may suggest that some failure mechanisms are dependent upon the state of the cell over a period of time, as such rechargeable sources of energy experience many charging and discharging cycles.
UL has hence proposed a project to investigate the safety performance in aged lithium-ion cells.
After a series of study, the polarization effect and the shift in the thermal properties in aged cells are found to be the major causes to safety concerns. >> More
