Skeleton Technologies -
powering energy savings
with ultracapacitors

Skeleton Technologies brand values

Ever since we first started developing our graphene-based ultracapacitors in 2009, we have been steadfast in our aim to change the energy storage industry. Today, our SkelCap ultracapacitors, based on patented “curved graphene” represent the biggest technological advancement in the industry in the last 20 years.

For us, developing and producing the best ultracapacitor cells, modules, and systems in the world is means to an end: helping companies save energy. Ultracapacitors excel where other energy storage technologies fail and this gives us the opportunity to help companies that otherwise might not be able to hybridize or electrify their businesses.


Technology & Applications


Our proprietary raw material, “curved graphene”, provides our ultracapacitors with an unparalleled advantage in power and energy density. We power energy savings with ultracapacitors in automotive, transportation, grid & renewables, maritime, industrial manufacturing, and material handling.
