Redox shuttle additives are used to protect lithium ion batteries from electrolyte oxidation and overheating during overcharge conditions. The additive protects the cell by becoming involved in a futile redox cycle that pins the cathode potential near the redox potential of the shuttle molecule. Since the material eventually becomes consumed in side reactions, high solubility of the parent molecule and high chemical stability of the charged molecule are required for durable protective action. Furthermore, we demonstrate a highly soluble (0.6 M) 1,4-dialkoxybenzene redox shuttle molecule that provides overcharge protection over 500 cycles at a C/2 rate and 100% overcharge ratio, which places this additive far ahead of the current state of the art.
