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 17):
A method of making a negative electrode for an electrochemical cell that cycles lithium ions, the method comprising:\n pre-lithiating a negative electrode to produce a pre-lithiated negative electrode, wherein the negative electrode comprises a silicon-containing electroactive material and a first electrochemical cell comprises the negative electrode and a first electrolyte system, wherein the first electrolyte system comprises a fluorinated solvent and a first salt, and wherein the fluorinated solvent has a concentration in the first electrolyte system of greater than 3 M and the first salt has a concentration in the first electrolyte system of greater than 0.5 M; removing the pre-lithiated negative electrode from the first electrochemical cell; and constructing a second electrochemical cell, wherein the electrochemical cell comprises the pre-lithiated negative electrode and a second electrolyte system, wherein the second electrolyte system comprises a hydrocarbon solvent and a second salt, wherein the hydrocarbon solvent has a weight concentration in the second electrolyte system from about 75% to about 95% and the first salt has a concentration in the second electrolyte system from about 0.5 M to about 2.5 M.
