Knowing that LIB efficiency and survivability are greatly influenced by temperature, this study focuses on the thermo-electrochemical analysis of LIBs in space orbit. Current finite element modeling software allows for advanced simulation of the thermo-electrochemical processes; however the heat transfer simulation capabilities of said software suites do not allow for the extreme complexities of orbital-space environments like those experienced by the ISS. In this study, we have coupled the existing thermo-electrochemical models representing heat generation in LIBs during discharge cycles with specialized orbital-thermal software, Thermal Desktop (TD). Our model's parameters were obtained from a previous thermo-electrochemical model of a 185 Amp-Hour (Ah) LIB with 1–3 C (C) discharge cycles for both forced and natural convection environments at 300 K. Our TD model successfully simulates the temperature vs. depth-of-discharge (DOD) profiles and temperature ranges for all discharge and convection variations with minimal deviation through the programming of FORTRAN logic representing each variable as a function of relationship to DOD. Multiple parametrics were considered in a second and third set of cases whose results display vital data in advancing our understanding of accurate thermal modeling of LIBs.</p> </div> <!-- END OUTPUT from 'themes/crtechd9/templates/classy/field/field--text-with-summary.html.twig' --> <!-- THEME DEBUG --> <!-- THEME HOOK: 'field' --> <!-- FILE NAME SUGGESTIONS: * field--node--field-upload-files--publication-files.html.twig * field--node--field-upload-files.html.twig * field--node--publication-files.html.twig * field--field-upload-files.html.twig * field--file.html.twig x field.html.twig --> <!-- BEGIN OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <div class="field field--name-field-upload-files field--type-file field--label-inline clearfix"> <div class="field__label">Upload Files</div> <div class="field__item"> <!-- THEME DEBUG --> <!-- THEME HOOK: 'file_link' --> <!-- BEGIN OUTPUT from 'themes/crtechd9/templates/field/file-link.html.twig' --> <span class="file file--mime-application-pdf file--application-pdf"> <a href="/sites/default/files/publications/TD_Application_0.pdf" type="application/pdf">TD_Application.pdf</a></span> <!-- END OUTPUT from 'themes/crtechd9/templates/field/file-link.html.twig' --> </div> </div> <!-- END OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <!-- THEME DEBUG --> <!-- THEME HOOK: 'field' --> <!-- FILE NAME SUGGESTIONS: * field--node--field-source--publication-files.html.twig * field--node--field-source.html.twig * field--node--publication-files.html.twig * field--field-source.html.twig * field--string.html.twig x field.html.twig --> <!-- BEGIN OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <div class="field field--name-field-source field--type-string field--label-inline clearfix"> <div class="field__label">Source</div> <div class="field__item">Science Direct (Journal of Power Sources)</div> </div> <!-- END OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <!-- THEME DEBUG --> <!-- THEME HOOK: 'field' --> <!-- FILE NAME SUGGESTIONS: * field--node--field-author--publication-files.html.twig * field--node--field-author.html.twig * field--node--publication-files.html.twig * field--field-author.html.twig * field--string.html.twig x field.html.twig --> <!-- BEGIN OUTPUT from 'themes/crtechd9/templates/classy/field/field.html.twig' --> <div class="field field--name-field-author field--type-string field--label-inline clearfix"> <div class="field__label">Author</div> <div class="field__item">W.
