Ultracapacitor energy storage solutions based on breakthrough graphene materials

Ultracapacitors, or supercapacitors as they are also known, are an energy storage technology that offers high power density, almost instant charging and discharging,  high reliability, and very long lifetimes.

Ultracapacitors provide the following benefits:

Long lifetimes

Typical ultracapacitor lifetime is about 10-20 years and 500k to 1m charge/discharge cycles

Wide Temperature Range

Wider range of operating temperatures from -40 °C to 65 °C

Fast Charge/Discharge

100x faster charging and discharging than batteries

Maintenance Free Operation

Once installed, they require no additional maintenance and have simple monitoring

Improved Power Density

Up to 60 times the power density achieved by batteries

Environmentally Friendly

Ultracapacitors do not contain hazardous or hard-to-recycle materials

Improved Efficiency

Up to 30% more efficient than batteries in full load conditions 

Safety in Operation

Compared to lithium and lead based battery chemistries, ultracapacitors eliminate the risk of self ignitionor explosion

EnyGy® develops, manufactures and markets graphene-based electrode films, graphene-based ultracapacitors and graphene materials to improve upon existing ultracapacitors in the market.
