Computer Simulation of Thermal Modeling of Primary Lithium Cells
01 Sep 1987
Abstract
The objective was to gain a better understanding of the safety problem of primary LI-SOCl z and LI-SO 2 cells by carrying out detail thermal modeling work. in particular, the transient heat generation rates during moderate and extremely high discharge rate tests of LI-SOCl z cells were predicted and compared with those from the electrochemical heating. The difference between the two may attributed to the lithium corrosion and other chemical reactions. The present program was also tested for charging tests of LI-SO 2. In addltlon,the present methodology should be applicable to other primary cy1lndrlcal cells as well as rechargeable battery analyses with minor modifications. I NTRODUCT I ON The present Investigation Is an extension of our earlier work of a simple transient model, which used the lumpeO-heat-capaclty method to predict the tlme-dependent cell temperature of primary IIthi_m-thlonyl chloride (LI-SOCl Z) cells [I]. However, the thermal Impact of internal thermal resistances on the overall heat dissipation was not Included In the previous analysis. In addition, the heat transfer coefficient h, which Is a function of temperature and position, was assumed to be constant In the previous study to demonstrate the validity of methodology. The purpose of the present thermal modeling work was to develop a computer program to take Into account the effects of internal thermal PINI_EDI_._GPAGE BLANK NOT F_M'FJ)
