Skeleton Technologies has advanced the state of energy storage with its SuperBattery® technology, a high-performance solution engineered to bridge the long-standing gap between conventional lithium-ion batteries and ultracapacitors. Built on Skeleton’s proprietary Curved Graphene® material, SuperBattery is designed to deliver exceptionally high-power density, ultra-fast charging capability, and extended cycle life, while maintaining a strong focus on safety and sustainability.
SuperBattery combines capacitor-like power characteristics with significantly higher usable energy than traditional supercapacitors. The Curved Graphene® electrode architecture enables very low equivalent series resistance (ESR), minimizing resistive losses and heat generation during high-current operation. As a result, SuperBattery cells can charge in less than 90 seconds and sustain tens of thousands of charge–discharge cycles, far exceeding the cycling capability of typical lithium-ion chemistries while maintaining stable performance.
Skeleton’s SuperBattery portfolio includes cylindrical cell formats such as the D35 and D60, optimized for high-power and short-duration energy applications. These cells deliver power densities in the multi-kilowatt per liter range alongside meaningful energy density, enabling compact system designs capable of handling rapid power transients. The inherent electrochemical stability of the Curved Graphene® system significantly reduces thermal runaway risk, supporting safe operation under high currents, rapid charging, and extreme operating conditions.
The SuperBattery technology is deployed in modular solutions such as Graphene-based Battery Backup Units (BBUs) for data centers and critical infrastructure. These systems integrate advanced DC/DC power electronics and intelligent battery management systems (BMS) to deliver regulated, high-efficiency power, supporting peak power levels in the megawatt range for short durations. In data center applications, SuperBattery-based BBUs enable near-instantaneous ride-through during grid disturbances, reducing reliance on diesel generators and improving overall power system resilience.
Graphene BBU Modules for Data Centers
SuperBattery technology eliminates the need for lithium, cobalt, nickel, and other critical battery materials, improving recyclability and reducing exposure to volatile supply chains. Its long service life and high efficiency further contribute to a lower total cost of ownership and reduced environmental impact across the product lifecycle.
By combining fast charging, high power, long lifetime, and intrinsic safety, SuperBattery positions itself as a compelling solution for data centers, grid support, transportation, aerospace, and industrial power buffering, where rapid response and reliability are paramount.
