Elimination of Irreversible Capacity of Amorphous Silicon: Direct Contact of the Silicon and Lithium Metal

A method of elimination of the amorphous silicon irreversible capacity is suggested, which is based on the direct contact of the silicon and lithium metal under electrolyte. It is shown that this contact yields a solid-electrolyte film over the electrode surface even prior to its initial cathodic polarization, which results in the elimination of the irreversible capacity of amorphous silicon.
