Positive or Negative Anode/Cathode in Electrolytic/Galvanic Cell
$begingroup$ @user2612743 In an electrolytic cell you are the person that determines which electrode is positive and which is negative via the external potential. And this external potential doesn''t get altered in the course of the reaction because the "sucked in" electrons are transported away by the voltage source.

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.
Without prelithiation, MWCNTs-Si/Gr negative electrode-based battery cell exhibits lower capacity within the first 50 cycles as compared to Super P-Si/Gr negative electrode-based full-cell. This could be due to the formation of an SEI layer and its associated high initial irreversible capacity and low ICE (Figure 3a, Table 2).
