LiCAP Develops Ultracapacitor Energy Storage Solutions for AI Data Centers

LiCAP Technologies Inc. has announced its new Rack Level Ultracapacitor Energy Storage System engineered for the high-power, fast-response demands of AI data centers.

Building onto its ultracapacitor cells and modules, LiCAP is expanding its product portfolio including build-to-spec rack-level systems designed to respond within milliseconds to AI workload transients, voltage disturbances and other short-duration power events.

The rapid growth of AI computing is changing data center power requirements. GPU-intensive workloads can create sharp, sub-second changes in power demand that place stress on utility feeds, generators, UPS systems, and batteries. Ultracapacitors are designed for the high-power, rapid charge-and-discharge cycles needed to help stabilize these sudden load changes, complementing batteries and generators that support longer-duration energy needs.

LiCAP ultracapacitor systems are designed to provide more than one million cycles 15+ years of expected service life and near-zero maintenance, making them well suited for frequent high-power cycling.

Applications

• AI power transient support and peak shaving: Rapidly delivers or absorbs power during sudden workload changes, reducing stress on primary power infrastructure
  
• Voltage sag support: Responds within milliseconds to short-duration voltage disturbances
  
• Bridge power: Supplies immediate power between grid interruption and the availability of longer-duration backup generation or storage
  
• Shutdown Protection: Provides short-duration power to complete active data writes, preserve in-process data, and enable controlled server shutdowns during unexpected power interruptions
  
• Battery Support: Handles high-power transient loads that can accelerate battery degradation

LiCAP’s rack-level systems can be tailored to customer specific voltage, power, energy, runtime and physical-integration requirements and integrated with a Cabinet Management System for real-time monitoring of system status, health and safety.

LiCAP’s ultracapacitors are enabled by the company’s patented Activated Dry Electrode® (ADE) manufacturing technology.  The dry-electrode manufacturing process eliminates NMP solvent and associated drying and solvent-recovery steps while supporting low internal resistance and leakage current for fast response, reduced energy loss and lower thermal stress.

Key Events

LiCAP will showcase its ultracapacitor technology and products at Battery & Energy Storage Tech Europe in Barcelona from September 8–9, 2026, and The Battery Show North America in Detroit from October 12–15, 2026.

Key Quote

“AI is changing the data center power equation,” said Richard Qiu, President of LiCAP Technologies. “The challenge is no longer only how much backup energy a data center has, but also how quickly and repeatedly the power infrastructure can respond to dramatic changes in load. Ultracapacitors address the high-power, short-duration demands that batteries alone were not designed to handle, making the two technologies highly complementary.”
