Organic Salt Cathode Active Material Electrode with Ionically Bonded Non-Coordinating Anions

This technology involves manufacturing a cathode active material in the form of an organic salt by ionically bonding a non-coordinating anion, hexafluorophosphate (PF6-), to an organic compound (5,10-dimethylphenazine), thereby controlling its solubility in electrolytes.

In organic batteries, organic compounds used as cathode active materials often dissolve easily into the electrolyte, leading to issues such as self-discharge, poor cycle life, and battery short circuits caused by the shuttle effect.

This technology converts 5,10-dimethylphenazine into 5,10-dimethylphenazinium hexafluorophosphate salt using an oxidizing agent such as silver hexafluorophosphate for use as a cathode active material. When combined with a concentrated electrolyte, it significantly reduces the solubility of the organic compound, allowing for the stable achievement of the properties required for lithium secondary battery cathode materials.
