Abstract

See full text

A method for fabricating an anode for a lithium ion battery cell is described and includes forming a solid electrolyte interface (SEI) layer on a raw anode prior to assembly into a battery cell by applying a first SEI-generating electrolyte to the raw anode to form a first intermediate anode, applying a second SEI-generating electrolyte to the first intermediate anode to form a second intermediate anode, and applying a third SEI-generating electrolyte to the second intermediate anode to form a cell anode, wherein the cell anode includes the raw anode having the SEI layer. Thus, a cell anode is formed by sequentially applying SEI-generating electrolytes to a raw anode to form the cell anode with an SEI layer, and a lithium ion battery cell is formed by assembling the cell anode into a cell pack, with a cathode, and a separator, and adding a cell electrolyte prior to sealing.
