Abstract

A method for producing a volume change compensated silicon: silicon oxide: lithium composite (SSLC) material is disclosed. The method includes producing an initially prelithiated SSLC material; delithiating the initially prelithiated material to produce a delithiated SSLC material; and performing at least one iteration of a volume change compensation process involving: (a) re-prelithiating the delithiated SSLC material to produce a re-prelithiated SSLC material; and (b) delithiating the re-prelithiated SSLC material produced in (a), wherein at least one of the following is satisfied: (i) prior to performing the at least one iteration of the volume change compensation process the initially prelithiated SSLC material is essentially completely lithiated; and (ii) at least one iteration of the volume change compensation process produces a re-prelithiated SSLC material that is essentially completely prelithiated. In a final iteration of the volume change compensation process, delithiating the re-prelithiated SSLC material produced in (a) completely delithiates the re-prelithiated SSLC material to produce the volume change compensated SSLC material. The aforesaid process is performed prior to, or ex situ with respect to, the fabrication of an anode that contains the produced volume change compensated SSLC material.
