Thus, the use of a heat pipe in lithium-ion batteries to improve heat dissipation represents an innovation. A two-dimensional transient thermal model has also been developed to predict the heat dissipation behavior of lithium-ion batteries. Finally, theoretical predictions obtained from this model are compared with experimental values. 2.
Consequently, temperature distribution and heat dissipation are important factors in the development of thermal management strategies for lithium-ion batteries.
Although there have been several studies of the thermal behavior of lead-acid , , , lithium-ion , and lithium-polymer batteries , , , , heat dissipation designs are seldom mentioned.
Although its use for cooling electronic applications has met with some success , it has seldom been employed in heat dissipation designs for batteries. Thus, the use of a heat pipe in lithium-ion batteries to improve heat dissipation represents an innovation.
A two-dimensional, transient heat-transfer model for different methods of heat dissipation is used to simulate the temperature distribution in lithium-ion batteries. The experimental and simulation results show that cooling by natural convection is not an effective means for removing heat from the battery system.
Chen and Evans investigated heat-transfer phenomena in lithium-polymer batteries for electric vehicles and found that air cooling was insufficient for heat dissipation from large-scale batteries due to the lower thermal conductivity of polymer as well as the larger relaxation time for heat conduction.
