Thermodynamic Potential#

Thermodynamic Potential = {model_name} {float_list}

Description / Usage#

This card is used to specify the anodic or cathodic thermodynamic potential in a thermal battery cell.

{model_name}

Name of thermodynamic potential model. Currently, two thermodynamic potential models are available, namely LiSi and FeS2. Each of these and their accompanying input parameters (the <float_list>) is given below:

LiSi

This model requires seven floating-point parameters:

<float1> - Limit of electrode utilization for the first anode reaction.

<float2> - Limit of electrode utilization for the second anode reaction.

<float3> - Anode thickness.

<float4> - Anode porosity.

<float5> - Molar volume of active anode material.

<float6> - Current density output by the thermal battery cell.

<float7> - Number of electrons involved in anode reactions.

FeS2

This model requires eight floating-point parameters:

<float1> - Limit of electrode utilization for the first cathode reaction.

<float2> - Limit of electrode utilization for the second cathode reaction.

<float3> - Limit of electrode utilization for the third cathode reaction.

<float4> - Cathode thickness.

<float5> - Cathode porosity.

<float6> - Molar volume of active cathode material.

<float7> - Current density output by the thermal battery cell.

<float8> - Number of electrons involved in cathode reactions.
