Patent abstract
In an example of a method for enhancing the performance of a silicon-based negative electrode, the silicon-based negative electrode is pre-lithiated in an electrolyte including a lithium salt dissolved in a solvent mixture of dimethoxyethane (DME) and fluoroethylene carbonate (FEC). The DME and FEC are present in a volume to volume ratio ranging from 10 to 1 to 1 to 10. The pre-lithiation forms a stable solid electrolyte interface layer on an exposed surface of the negative electrode.
