Abstract
An organic active material, having good energy density and electrochemical stability, for use in an electrochemical cell is disclosed. Electrochemical cells that employ the organic active material are also disclosed. The organic active material is a bridged-ring organic molecule having a nitroxy moiety, the nitroxy moiety being capable of two-electron oxidation/reduction through three distinct redox states. In different implementations, the organic active material can be incorporated in a solid electrode or can be employed as a fluid active material such as is useful for a flow cell. In different variations, the organic active material can be employed as a cathodic active material or as an anodic active material.
