Cooling of a Prismatic Battery
Introduction
This tutorial models the internal temperature distribution in a prismatic battery during a high-rate charge.
The electrochemical model deploys a lumped two-electrode model to define the active layers of the battery cell (the “jelly roll”), in combination with a space-dependent model for the electronic current conduction in the current collectors plates (arrester tabs), the current collector foils and the terminals.
The resulting heat sources from the electrochemical model are coupled to a heat transfer model, where anisotropic thermal conductivities are used to define the layer orientation within the homogenized jelly roll domains.
Some model parameters and the geometry design were taken from Ref. 1. Experimental verification, using internal temperature probes, of a similar model has previously been reported in Ref. 2.
Model Definition
Figure 1: Model geometry.
The following domains and materials (taken from the Built-in material library, when available) are defined in the model geometry:
Cell can (Aluminum)
Cap (Aluminum)
Spacer (Acrylic plastic)
Seal (Acrylic plastic)
Terminals (Copper/Aluminum)
Free electrolyte (user-defined Electrolyte material)
Metal foils (homogenized mixture of Copper/Aluminum and Electrolyte)
Figure 1 shows the model geometry. Due to the symmetric design of the prismatic battery, comprising two jelly rolls, the model geometry defines one half of the full battery. The terminals, electrically insulated from the cap by the use of a plastic spacer and seal, are placed at the top of the geometry. The jelly roll is defined as a union of a rectangular block and two semi cylinders.
Figure 2 shows a closeup of the region around the negative terminal. The bundle of metal foils protruding from the jelly roll are defined as a single domain in the geometry.
Figure 2: Closeup of the negative terminal, current collector plate and foils.
Battery Cell Model
The battery cell model in the jelly roll is defined using the Lumped Battery, Two Electrodes interface. The half-cell equilibrium potential curves for the two electrode materials, representing graphite and LiFePO4 (LFP) are taken from the Battery material library.
The cell model is set to an initial state of charge (SOC) of 10% and is subjected to a 4C galvanostatic charge up to 80% SOC. The end SOC is implicitly defined by end time in the Time Dependent study node.
Electric Potential Distribution in the Current Conductors
A Primary Current Distribution interface is used to model the electric potential distribution in the current conductors (the terminals, the current collector plates and the foil domains). Ground conditions are used at the topmost boundaries of the terminals, whereas Electrode Current conditions corresponding to the 4C cell current are defined on the boundaries between the jelly roll and foil domains.
Heat Transfer
A Heat Transfer interface is used to model the temperature distribution in the whole geometry, where the heat sources derived in the Lumped Battery and Primary Current Distribution interfaces are added by the use of Electrochemical Heating multiphysics nodes.
The metal foils bundles are treated as homogenized domains, where the thermal properties in the metal/electrolyte mix is defined by the use of Porous Material material nodes.
To handle the anisotropic thermal conductivity in the jelly roll, the Battery Layers node is used, defining different in-layer and through-layer thermal conductivities. This node automatically defines cylindrical coordinate systems, with different defined origins, for the two half cylinders, and a cartesian coordinate system for the rectangular block.
The battery is assumed to be placed on a cooling plate with a defined constant temperature. This is modeled using a Temperature boundary node, setting a fixed temperature of 35ºC at the bottom exterior boundary. In addition, convective cooling conditions are added by the use of a Heat Flux node on the top and side boundaries. It is assumed that the battery is placed in an array of identical batteries, extending in the y direction. For this reason the default Thermal Insulation boundary condition is used on the front and back exterior boundaries.
The initial temperature of the battery is set to 35ºC.
Results and Discussion
Figure 3 shows the battery voltage versus time. The plateaus in the cell voltage over time stem from the equilibrium potential profile of graphite (the negative electrode material).
Figure 3: Cell voltage versus time.
Figure 4 shows the electric potential with respect to the end terminal boundaries in the current conductors. Slightly higher potential drops are seen in the positive current conductors. This an effect of the lower electrical conductivity of aluminum.
Figure 5 shows the temperature distribution (at the end of the simulation) in the whole battery. The highest temperatures are observed close to the terminals.
Figure 4: Electric potentials in the current conductors.
Figure 5: Temperature distribution in the whole battery.
Figure 6: Temperature distribution in the current conductors and the jelly roll.
Figure 7: Temperature distribution in the jelly roll.
Figure 6 and Figure 7 shows the temperature distribution in the jelly roll and current conductors, and the jelly roll only, respectively, whereas Figure 8 shows a slice plot of the temperature in the jelly roll. The jelly roll temperature is generally higher in the regions closer to the positive terminal. This is an effect of the lower electric conductivity of the aluminum current conductors, giving rise to higher Joule heating heat sources.
