The next generation of battery technology is here!


Sirius Energy Storage

In our electrical and electronics driven world, batteries have become common and their importance continues to increase with the increased focus on energy management and renewable integration. Historically, the focus has been around chemical battery storage systems which includes the well-known lead acid, alkaline and more recently, lithium ion chemistries which allow for reduced lifecycle costs. Chemical battery storage systems have several limitations including degradation of charge capacity, limited life cycles, narrow operational temperature windows, limitations on charging and discharging rates, explosion or runaway risks and environmentally hazardous chemical components to name a few.

The energy density of traditional capacitors has limited their use as extended duration energy storage devices. This has been changed with the development of super capacitors that significantly increase the energy density of traditional capacitors making them more amenable to longer duration storage solutions. In addition, this new generation of energy storage mitigates many of the issues found in traditional chemical batteries.

Finally, thanks to their environmentally friendly nature and long cycle life, use of super capacitors can reduce costs associated with maintenance, disposal and global environmental taxes as well as reduction in environmental impacts of high powered systems.


Highly efficient with negligible DC to DC losses during cycling.

No capacity or efficiency degradation over projected cycle life.

Non toxic, with no risk of thermal runaway.

Wide operating temperature range of supercap cells.

Supercap cell cycle life and capacity unaffected by high rate of charge or discharge.

Long cycle life – defers disposal cost and mitigates environmental impact.
