Sirius Energy Storage
The world’s first supercapacitor-based energy storage system
Sirius Energy Storage products for stationary applications are currently available in selected markets. This modular and scalable system provides a technically and commercially viable, plug-and-play replacement for chemical batteries.
Key Attributes
• Actively balanced and stable operation at all commercial voltages
• Flat discharge curve (module discharge rate is determined by the load)
• 2% per month self-discharge when idle and in sleep mode
• Cell level energy density of 70-80Wh/kg
• Supercap cell cycle life and capacity unaffected by high rate of charge or discharge
• Supercap cell projected calendar life of 45 years and cycle life of 1,000,000 cycles
• High charge / discharge capability
• Wide operating temperature range of supercap cells
• No degradation of capacity and efficiency over cycle life
• Works with standard inverters/rectifiers/regulators used with Lead Acid or Li Ion batteries
• Non-toxic, with no risk of thermal runaway
• Form factor similar to chemical batteries
