EEStor’s ultra-capacitors combine Barium Titanate, Aluminum Oxide, and glass.
Previous super-capacitors were impractical, only about .02MJ/kg.
EEStor ultra-capacitors expected up to 2.5MJ/kg.

ConclusionConclusion
Increasing demand for portable electronics
Allows for real feasibility of electric vehicles.
With greater EESU efficiency, new applications now possible.
