Abstract
Provided is anode active material for use in a lithium ion battery, wherein the anode active material is capable of reversibly storing lithium ions therein up to a maximum lithium storage capacity Cduring a charge or discharge of the battery and the anode active material comprises an amount of solid-electrolyte interphase (SEI) on a surface or in an internal structure of the anode active material wherein the SEI is pre-formed prior to incorporating the anode active material in an anode electrode of the battery. Also provided is a method of producing the pre-formed SEI substances in the anode material; e.g. through repeated lithiation/delithiation procedures.
