Energy storage arrangement, method for the controlled discharge of an energy storage by means of redox shuttle additives and use of a redox shuttle additive

摘要

Energy storage arrangement, comprising (1) an energy store having at least one negative electrode "anode", at least one positive electrode "cathode", electrolyte and electrical poles, via which the energy store is at least dischargeable, (2) a storage container containing a redox shuttle Additive, and (3) a triggerable dispensing device, by means of which the redox shuttle additive is released into the electrolyte of the energy store such that the cathode and the anode of the energy store are in contact with the redox shuttle additive present in the electrolyte and partially or completely discharging the energy store by oxidizing the redox shuttle additive at the cathode and reducing it at the anode, the redox shuttle additive having a redox potential that is less than or equal to the potential of the partially or fully discharged cathode and greater than or equal to the potential of partially or completely discharging an anode is.
