Abstract
A liquid catholyte as well as electrochemical cells and automotive vehicles employing the liquid catholyte are disclosed. The liquid catholyte includes a quinone as redox active material and a fluoroalkylsulfonyl salt as charge balancing agent and is characterized by a liquid form of the redox active material regardless of redox state. The liquid catholyte can thus have utility as a catholyte in a flow battery.
