There are new supercapacitors being commercialized with 60 watt hours of energy density and 100 watt hour energy density is being reported in lab results.

Yunasko is commercializing a 40 watt hour per kilogram hybrid battery-supercapacitor.

The University of Surrey has reported contact lens polymer materials offering supercapacitors that are between 1,000-10,000 times more powerful than existing supercapacitors.

There are also research on graphene based supercapacitors which also are promising to beat batteries on energy density.
