Abstract
An electrochemical cell including an additive mixture for alleviating the symptoms of overcharge is disclosed. The additive mixture may include a combination of at least two of diethyl allylphosphonate, 4-fluorobiphenyl, and 1-phenyl-1-cyclohexene. For example, an electrolyte may include allylphosphonate and 4-fluorobiphenyl. In yet another example, an electrolyte may include 1-phenyl-1-cyclohexene.
