Original Abstract Submitted
An electrochemical cell that cycles lithium ions includes a positive electrode that includes a positive electroactive material, a negative electrode that includes a silicon-containing negative electroactive material, a separating layer disposed between the positive electrode and the negative electrode, and an electrolyte that is in contact with at least one of the positive electroactive material, the negative electroactive material, and the separating layer. The electrolyte includes greater than or equal to about 0.1 wt. % to less than or equal to about 10 wt. % of a phosphite-type additive.
