By performing linear stability under (dis)charging conditions, we characterize the phase stability of the system as a function of the heat transfer Dahmkohler number, which compares the reaction to heat generation rates. Additionally, we identify the effects of different ion intercalation reaction mechanisms and demonstrate the importance of the limiting current as a result of electron transfer limitations to both the heat generation and nonequilibrium phase stability of the system. Finally, we discuss the implications of our findings on the design of Li-ion batteries, and speculate their application on other open driven systems, such as photocatalysis and electrodeposition.
