1 Introduction. In lithium-ion battery production, the formation of the solid electrolyte interphase (SEI) is one of the longest process steps. [] The formation process needs to be better understood and significantly shortened to produce cheaper batteries. [] The electrolyte reduction during the first charging forms the SEI at the negative electrodes.
