A Model of Chemical Power Source CPS Self-Discharge

1 A Model of Chemical Power Source (CPS) Self-Discharge 

At the point of the electrolyte contact, a chemical reaction proceeds with the rate  

Due to this reaction, the local cell in the defect region becomes more discharged in comparison with the main cell. A current I arises charging the defect region  

The sum of Eqs. (5.37) and (5.41) is a differential equation of the oxidiser mass balance with two variables—concentration and temperature. The conductivity of the cell, K, is also, in general, temperature-dependent, and this dependence should be similar to Eq. (5.38) if the migration of ions through the film at the lithium surface determines the cell resistance. 

The second differential equation presents the heat balance of the local cell
