Although statistically very safe and reliable, there have been some exceptional incidents involving lithium ion batteries catching fire. Overcharging a lithium ion battery can cause the cathode can react with and decompose the electrolyte solution, generating heat and reactive gases. Incorporation of overcharge prevention into lithium-ion batteries is, therefore, key to improving their safety. Redox shuttle molecules, that can be reversibly oxidized and reduced at specific potentials, provide an effective and economic method to prevent overcharge abuse for lithium-ion batteries.
