An energy storage medium comprising a charge storage material dissolved in an aqueous media, wherein
- (i) the charge storage material comprises a perylene diimide core;
- (ii) the charge storage material is in a 2-electron reduced state when the energy storage medium is fully charged;
- and
- (iii) the charge storage material shows less than 1% degradation when stored for 11 days in a 2-electron reduced state.
An energy storage medium comprising a charge storage material dissolved in an aqueous media, wherein
- (i) the charge storage material comprises a perylene diimide core;
- (ii) the charge storage material is in a 2-electron reduced state when the energy storage medium is fully charged;
- and
- (iii) the charge storage material is stable for at least one year.
An energy storage medium comprising a charge storage material dissolved in an aqueous media, wherein
- (i) the charge storage material comprises a perylene diimide core;
- (ii) the charge storage material is in a 2-electron reduced state when the energy storage medium is fully charged;
