So why are Ultracapacitors not used in more applications already?
14
+ Currently ultracapacitors can be found in 4 million passenger vehicles
+ Price and performance are the main market drivers and key to the take-off of the ultracapacitor market
+ Major OEMs have set a price target of 0.25-0.3 $cents/F -current market prices are ca 0.7 to 1 $cents/F, showing a 5% decline YoY

+ Market demand for UC energy density shows a clear gap
+ Current generations of Ultracapacitors can only fulfil partial energy demands
+ Ultracapacitors with higher energy density can help to downsize batteries in many applications
Two simple answers (2): Energy Density

Ultracapacitor Applications
Conclusions
• Energy storage applications are getting more power hungry
• Batteries need to be oversized in order to serve high power applications
• Ultracapacitors are optimal for high power applications
• Hybridization of Ultracapacitors and LiBs can yield more efficient and cheaper energy storage for multiple applications
• Current Ultracapacitor technology lacks energy density
• Skeleton Technologies is on track to double the energy density of Ultracapacitors until 2021
