The　chemical　reactions　taking　place　in　lithium-ion　batteries　can　trap　lithium　and　alter　the　distribution　of　lithium　and　the　deformation　of　the　electrode　during　electrochemical　charging　and　discharging.　In　this　work,　we　incorporate　the　strain　generated　by　chemical　reactions　in　the　transient　analysis　of　diffusion-induced　stress　and　numerically　solve　the　one-dimensional　problem　under　galvanostatic　and　potentiostatic　operations,　respectively.　The　numerical　results　show　that　both　the　diffusion　and　local　chemical　reaction　contribute　to　the　expansion　of　the　electrode.　Under　the　potentiostatic　operation,　lithiation　introduces　a　stress　spike　at　the　fixed　end　at　the　onset　of　the　lithiation.　The　chemical　reactions　play　a　significant　role　in　controlling　the　temporal　evolution　of　lithium　and　the　deformation　of　electrode,　which　needs　to　be　taken　into　account　in　the　analysis　of　structural　durability　of　lithium-ion　batteries.　©　2018,　Springer-Verlag　GmbH　Austria,　part　of　Springer　Nature.
