Abstract:
A method of making an electrochemical cell comprising a silicon-containing anode includes forming a first electrochemical cell comprising the silicon-containing anode and a first electrolyte system, pre-lithiating the silicon-containing anode to produce a pre-lithiated anode in the first electrochemical cell, and forming a second electrochemical cell including the pre-lithiated anode and a second electrolyte system. The first electrolyte system includes a fluorinated solvent in an amount greater than 5 wt % and a first salt; and the second electrolyte system includes a hydrocarbon and a second salt. Forming the second electrochemical cell may include removing the first electrolyte system from the first electrochemical cell and introducing the second electrolyte to the emptied first electrochemical cell; or removing the pre-lithiated anode from the first electrochemical cell and constructing the second electrochemical cell with the pre-lithiated anode and the second electrolyte system.

Claim (Index 6):
The method of  claim 1 , wherein the fluorinated solvent comprises a solvent selected from the group consisting of: fluoroethylene carbonate (FEC), difluoroethylene carbonate (DFEC), trifluoropropylene carbonate (TFPC), methyl 2,2,2-trifluoroethyl carbonate, ethyl 2,2,2-trifluoroethyl carbonate, 2,2-difluoroethyl methyl carbonate, 2,2-difluoroethyl ethyl carbonate, 2,2-difluoroethylacetate, 2,2,2-trifluoroethylacetate, 1,1,2,2-tatrafluoroethyl 2,2,3,3-tetrafluoropropylether, and combinations thereof; and\n wherein the hydrocarbon solvent comprises a solvent selected from the group consisting of: ethylene carbonate (EC), propylene carbonate (PC), vinylene carbonate (VC), dimethyl carbonate (DMC), ethyl methyl carbonate (EMC), diethyl carbonate (DEC), and combinations thereof, wherein the first salt and the second salt are independently selected from the group consisting of: lithium hexafluorophosphate (LiPF 6 ); lithium bis(fluorosulfonyl)imide (LiN(FSO 2 ) 2 ) (LiSFI); lithium bis(oxalato)borate (LiB(C 2 O 4 ) 2 ) (LiBOB); lithium difluorooxalatoborate (LiBF 2 (C 2 O 4 )); lithium perchlorate (LiClO 4 ); lithium tetrachloroaluminate (LiAlCl 4 ); lithium iodide (LiI); lithium bromide (LiBr); lithium thiocyanate (LiSCN); lithium tetrafluoroborate (LiBF 4 ); lithium tetraphenylborate (LiB(C 6 H 5 ) 4 ); lithium hexafluoroarsenate (LiAsF 6 ); lithium trifluoromethanesulfonate (LiCF 3 SO 3 ); bis(trifluoromethane)sulfonimide lithium salt (LiN(CF 3 SO 2 ) 2 ); and combinations thereof.
