Electrolyte compositions for stabilizing silicon electrodes in lithium batteries
Abstract
A lithium-ion electrochemical cell comprises a first electrode, a second electrode comprising elemental silicon, a microporous separator membrane between the first and second electrodes, and an electrolyte in contact with the electrodes and the membrane. The electrolyte comprises a lithium salt at a concentration in the range of about 0.1 M to about 5 M, and an additional metal salt at a concentration in the range of about 0.001 to about 5 M dissolved in an organic solvent. The additional metal salt comprises a metal cation that can form a lithium-silicon-metal Zintl phase; and the first electrode comprises metallic lithium or a cathode active material capable of donating and accepting lithium ions to and from the second electrode during electrochemical cycling. Electrolytes for use with silicon-containing electrodes also are described.
