Electricity-heat power and energy balance for Li/SOCl2 batteries

The heat management equation based on reaction enthalpy and experimental results has been investigated for Li/SOCl2 cells. The quantity of thermal resistance by experiment has been compared with the theoretical prediction. We define the critical temperature and pressure using phase equilibrium diagram in liquid and vapour; for sulfur dioxide, these values are 157.8 °C and 7.87 MPa, respectively.
