Ride-through power for
AI-scale load profiles.
Peak shaving, thermal tolerance, and uninterrupted duty cycles – without lithium’s risk profile.
Why batteries, why now
From grid burden to grid asset.
AI load is bursty – millisecond GPU spikes, a few hundred peak hours a year, and the occasional grid disturbance. A short-duration sodium-ion battery behind the meter handles all three, so the data hall draws a fraction of its peak from the grid and runs more compute per megawatt of connection.
Shave the peaks
Sub-second GPU spikes and short daily peaks are met from the battery, not the grid – smoothing a bursty AI load into a steady draw.
Ride through disturbances
UPS-grade backup at rack and facility density carries the hall through transients and short outages without lithium’s risk profile.
Free up the connection
Cutting the coincident peak lets a site run far more compute per megawatt of grid capacity.

The chemistry
Built for the duty cycle, not against it.
Data-center batteries cycle hard, sit inside occupied buildings, and cannot catch fire. Altris Prussian White sodium-ion is built for exactly that – high-rate power for GPU transients, long life under heavy cycling, and no thermal-runaway risk.

| For AI data-center duty | Lithium-ion (LFP / NMC) | Altris Na-ion |
|---|---|---|
| Cycle life under high C cycling | Shorter; capacity knee, then fast fade | ~10x LFP |
| High-rate GPU power spikes | Spikes erode cycle life | Absorbs high-rate pulses |
| Thermal-runaway risk | Real risk; needs suppression | None – no flammable solvents |
| Supply chain | ~65-80% China | Ex-China – 83% EU today |
| Embodied CO2 | Baseline | ~40% of LFP |
Common questions.
An Altris battery layer can discharge during short GPU and facility peak windows, then recharge off-peak, so the site draws a smoother load profile from the grid connection.
Yes. Sodium-ion cells are well suited to high-rate, short-duration power delivery for ride-through events and transient support, with application review used to confirm the right voltage, power, and cycle profile.
Altris sodium-ion chemistry is designed around high-rate cycling, abundant raw materials, and no thermal-runaway risk from flammable solvents, reducing safety and supply-chain pressure for data center operators.
