Group1 is developing power systems that keep AI infrastructure running through power interruptions, starting with modular backup power for edge computing and data centers.
We’ve built the potassium-ion cell.
Now we’re advancing toward integrated systems and a domestic supply chain, bringing American materials innovation to critical power infrastructure.
Inherently safer, high-power K-ion systems designed for mission-critical applications
Data centers require uninterrupted power for critical operations. Building on our completed potassium-ion cell, we are developing modular K-Pack and K-Cabinet systems for scalable backup power.
“Modular data centers will require nearly $7 trillion in capital expenditures by 2030 to meet skyrocketing demand for AI compute.”
Abundant potassium and compatibility with existing lithium-ion manufacturing infrastructure create a scalable path to backup power. Our chemistry brings four material-level advantages to demanding applications.
Our first focus is backup power for data centers and critical infrastructure. We are developing modular systems around our 18650 potassium-ion cell to meet demanding power and integration requirements.
Broader applications can build on the same cell platform as we scale.
AI data centers need immediate backup during power interruptions. Our K-Pack and K-Cabinet development targets high-power UPS applications, building on the completed 18650 cell.
Defense and critical infrastructure need dependable power and domestic supply chains. Group1’s American-made 18650 cells provide a foundation for these demanding applications.
Scalable stationary storage for grid and backup applications.
A lithium-free chemistry with potential for domestic transportation supply chains.
Compact power for robotics and autonomous systems.
