Thermal Analysis of Lithium‐Ion Batteries

Abstract

A thermal analysis of lithium‐ion batteries during charge/discharge and thermal runaway has been carried out with a mathematical model. The main concern with the thermal behavior of the room temperature batteries is the possible significant temperature increase which may cause thermal runaway. The emphases of this work include the examination of the effects of battery design parameters and operating conditions on temperature rise/profile during normal battery operation and the evaluation of the possibility of the occurrence of thermal runaway due to battery abuse.
